A synchronization gear (also known as a gun synchronizer or interrupter gear ) was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target.

143-499: The Mikoyan-Gurevich MiG-1 ( Russian : Микоян-Гуревич МиГ-1 ) was a Soviet fighter aircraft of World War II that was designed to meet a requirement for a high-altitude fighter issued in 1939. To minimize demand on strategic materials such as aluminum, the aircraft was mostly constructed from steel tubing and wood. Flight testing revealed a number of deficiencies, but it was ordered into production before they could be fixed. Although difficult to handle, one hundred were built before

286-649: A constitutional referendum on whether to adopt Russian as a second official language. According to the Central Election Commission, 74.8% voted against, 24.9% voted for and the voter turnout was 71.1%. Starting in 2019, instruction in Russian will be gradually discontinued in private colleges and universities in Latvia, and in general instruction in Latvian public high schools. On 29 September 2022, Saeima passed in

429-510: A new education law which requires all schools to teach at least partially in Ukrainian, with provisions while allow indigenous languages and languages of national minorities to be used alongside the national language. The law faced criticism from officials in Russia and Hungary. The 2019 Law of Ukraine "On protecting the functioning of the Ukrainian language as the state language" gives priority to

572-472: A "follower" on this cam wheel. At the same time the machine gun used was also changed – an lMG 08 machine gun, the so-called "Spandau", replacing the Parabellum used with the prototype gear. At this time the Parabellum was still in very short supply, and all available examples were required as observers' guns, the lighter and handier weapon being far superior in this role. The first victory using

715-415: A "safe" period, when the blades of the propeller were well out of the way, and this adjustment had to be checked at intervals, especially if the propeller was changed or refitted, as well as after a major engine overhaul. Faults in this adjustment (for example, a cam wheel slipping a millimetre or two, or a pushrod flexing) could well result in every bullet fired hitting the propeller, a worse result than if

858-482: A "safe" range before firing, otherwise risking speedy destruction of his propeller. The second requirement was for a gun that would reliably fire (or hold its fire) exactly when required. Not all automatic weapons were equally amenable to synchronization. When it was ready to fire, a synchronized machine-gun needed to have a round in the breech, the breech closed, and the action cocked (the so-called " closed bolt " position). Several widely used automatic weapons (notably

1001-827: A bit more, with 31 in the Baltic Military District , 37 in the Western Special Military District , one in the Kiev Military District and eight in the Odessa Military District for a total of 77 on hand, of which only 55 were operational. An additional eight MiG-1s were assigned to the Soviet Navy . However, only four pilots were trained to handle either the MiG-1 or the MiG-3. Little is known of

1144-522: A blocked fuel line caused a forced landing before the guns could be fired. Testing on a variety of other aircraft revealed very unsatisfactory performance from the guns and their development was canceled. The designers were arrested on 15 May 1941 and executed on 28 October 1941. On 3 December 1940 the VVS ordered that the 41st Fighter Regiment ( istrebitel'nyy aviatsionnyy polk ), based at the Crimean town of Kacha ,

1287-588: A cyclic rate of 800 or 1,000 rounds a minute, it was necessary to supply at least one impulse (if not two) for every rotation of the propeller, making it more liable to failure. The intricate mechanism of a mechanical linkage system, especially of the "push rod" type, could easily shake itself to pieces when driven at this rate. The final version of the Fokker Eindecker, the Fokker E.IV , came with two lMG 08 "Spandau" machine guns ; this armament became standard for all

1430-518: A flexible drive, a column of hydraulic fluid, a cable, or an electrical connection. Generally, mechanical systems were inferior to hydraulic or electric ones, but none were ever entirely foolproof, and synchronization gears at best always remained liable to occasional failure. The Luftwaffe ace Adolf Galland in his memoir of the war period The First and the Last describes a serious faulty synchronization incident in 1941. A pilot would usually only have

1573-434: A formula with V standing for the nucleus (vowel) and C for each consonant, the maximal structure can be described as follows: (C)(C)(C)(C)V(C)(C)(C)(C) Synchronization gear There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun 's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing

1716-558: A hard or soft counterpart, and the distinction is a prominent feature of the language, which is usually shown in writing not by a change of the consonant but rather by changing the following vowel. Another important aspect is the reduction of unstressed vowels . Stress , which is often unpredictable, is not normally indicated orthographically , though an optional acute accent may be used to mark stress – such as to distinguish between homographic words (e.g. замо́к [ zamók , 'lock'] and за́мок [ zámok , 'castle']), or to indicate

1859-479: A language that "belongs to the European cultural space". The financing of Russian-language content by the state will cease, which the concept says create a "unified information space". However, one inevitable consequence would be the closure of public media broadcasts in Russian on LTV and Latvian Radio, as well as the closure of LSM's Russian-language service. In Lithuania , Russian has no official or legal status, but

2002-572: A lesser extent the languages to the south and the east: Uralic , Turkic , Persian , Arabic , and Hebrew . According to the Defense Language Institute in Monterey, California , Russian is classified as a level III language in terms of learning difficulty for native English speakers, requiring approximately 1,100 hours of immersion instruction to achieve intermediate fluency. Feudal divisions and conflicts created obstacles between

2145-415: A machine gun's rate of fire exactly proportional to the revolutions per minute of a spinning aircraft propeller, would require an impractical level of complexity. A machine gun normally fires a constant number of rounds a minute, and while this may be changed by modifying the gun, it cannot be varied at will while the gun is operating. The rate of rotation of an aircraft propeller, meanwhile, especially before

2288-627: A method of firing forward through a tractor propeller was the Swiss engineer Franz Schneider , formerly with Nieuport , but by then working for the LVG Company in Germany. The patent was published in the German aviation magazine Flugsport in 1914, meaning that the concept became public knowledge at an early stage. The linkage between the propeller and the gun is achieved with a spinning drive shaft, rather than

2431-607: A minority language under the Framework Convention for the Protection of National Minorities . 30% of the population was fluent in Russian in 2006, and 2% used it as the main language with family, friends, or at work. In Azerbaijan , Russian has no official status, but is a lingua franca of the country. 26% of the population was fluent in Russian in 2006, and 5% used it as the main language with family, friends, or at work. In Georgia , Russian has no official status, but it

2574-548: A new Experimental Construction Section (OKO), headed by Artem Mikoyan and Mikhail Gurevich , which remained formally subordinated to the Polikarpov bureau until June 1940. Further work upon the I-200 design was assigned to Mikoyan and Gurevich, who later became recognized — not with full justice — as its designers. The MiG-1 was a low-wing monoplane with a tailwheel undercarriage of mixed construction. Due to shortages of light alloys,

2717-516: A qualitatively new entity can be said to emerge—the general language of the working class... capitalism has the tendency of creating the general urban language of a given society. In 2010, there were 259.8 million speakers of Russian in the world: in Russia – 137.5 million, in the CIS and Baltic countries – 93.7 million, in Eastern Europe – 12.9 million, Western Europe – 7.3 million, Asia – 2.7 million, in

2860-425: A reciprocating rod. The impulses needed to operate the trigger, or in this case to prevent the trigger from operating, are produced by a cam wheel with two lobes at 180° apart situated at the gun itself since firing is to be interrupted by both blades of the propeller. No attempt was made (so far as is known) to build or test an actual operating gear based on this patent, which attracted little or no official interest at

3003-453: A semi-automatic weapon rather than a completely automatic one. The third requirement is for a linkage between the "machines" (engine and gun) to be synchronized. Many early gears used an intricate and inherently fragile bell crank and push rod linkage that could easily jam or otherwise malfunction, especially when required to work at higher speeds than it had been designed for. There were several alternative methods, including an oscillating rod,

3146-403: A single gun, firing at a modest cyclic rate through a two-bladed propeller driven by a rotary engine, was becoming obsolete. Stangensteuerung gears for "stationary", i.e. , in-line engines, worked from a small cam immediately behind the propeller (see illustration). This produced a basic dilemma: A short, fairly robust push rod meant that the machine gun had to be mounted well forward, putting

3289-404: A single shot. The majority of these impulses would catch the gun in the process of ejecting a spent round or loading a fresh one, and would thus have no effect; but as soon as the firing cycle was completed, the gun would be ready to fire as soon as it received the next impulse from the synchronizing gear. The delay between the end of the firing cycle and the arrival of the next firing impulse slowed

3432-408: A synchronized "aircraft" gun such a delay can produce a rogue firing, sufficiently "out of time" for it to risk hitting the propeller. A very similar problem could arise where the mass of a special round (such as an incendiary or explosive one) was different enough to produce a substantial difference in muzzle velocity. This was compounded by the additional risk to the integrity of the propeller due to

3575-525: A synchronized gun-equipped fighter is now believed to have occurred on 1 July 1915 when Leutnant Kurt Wintgens of Feldflieger Abteilung 6b , flying the Parabellum-armed Fokker M.5K/MG aircraft "E.5/15", forced down a French Morane-Saulnier Type L east of Lunéville . Exclusive possession of a working gun synchronizer enabled a period of German air superiority on the Western Front known as

3718-477: A wide spread of fire that would have been impossible to match with the "safe zone" between the whirling propeller blades. Fokker's initial answer to this was the fitting of extra "followers" to the Stangensteuerung's large cam wheel, to (theoretically) produce the "ripple" salvo necessary to ensure that the guns were aimed at the same point on the propeller disc. This proved a disastrously unstable arrangement in

3861-527: Is Belarusian, among ethnic Belarusians this share is 28.5%; the highest share of those who speak Belarusian at home is among ethnic Poles — 46.0%. In Estonia , Russian is spoken by 29.6% of the population, according to a 2011 estimate from the World Factbook, and is officially considered a foreign language. School education in the Russian language is a very contentious point in Estonian politics, and in 2022,

4004-475: Is a co-official language per article 5 of the Constitution of Kyrgyzstan . The 2009 census states that 482,200 people speak Russian as a native language, or 8.99% of the population. Additionally, 1,854,700 residents of Kyrgyzstan aged 15 and above fluently speak Russian as a second language, or 49.6% of the population in the age group. In Tajikistan , Russian is the language of inter-ethnic communication under

4147-401: Is a high degree of mutual intelligibility between Russian, Belarusian and Ukrainian , and a moderate degree of it in all modern Slavic languages, at least at the conversational level. Russian is written using a Cyrillic alphabet. The Russian alphabet consists of 33 letters. The following table gives their forms, along with IPA values for each letter's typical sound: Older letters of

In the Southern Russian dialects , instances of unstressed /e/ and /a/ following palatalized consonants and preceding a stressed syllable are not reduced to [ɪ] (as occurs in the Moscow dialect), being instead pronounced [a] in such positions (e.g. несл и is pronounced [nʲaˈslʲi] , not [nʲɪsˈlʲi] ) – this

4433-647: Is an East Slavic language belonging to the Balto-Slavic branch of the Indo-European language family . It is one of the four extant East Slavic languages, and is the native language of the Russians . It was the de facto and de jure official language of the former Soviet Union . Russian has remained an official language of the Russian Federation , Belarus , Kazakhstan , Kyrgyzstan , and Tajikistan , and

4576-485: Is being used less frequently by Russian-speaking typists in favor of the extension of Unicode character encoding , which fully incorporates the Russian alphabet. Free programs are available offering this Unicode extension, which allow users to type Russian characters, even on Western 'QWERTY' keyboards. The Russian language was first introduced to computing after the M-1 , and MESM models were produced in 1951. According to

Consonants include a fricative /ɣ/ , a semivowel /w⁓u̯/ and /x⁓xv⁓xw/ , whereas the Standard and Northern dialects have the consonants /ɡ/ , /v/ , and final /l/ and /f/ , respectively. The morphology features a palatalized final /tʲ/ in 3rd person forms of verbs (this is unpalatalized in the Standard and Northern dialects). During the Proto-Slavic (Common Slavic) times all Slavs spoke one mutually intelligible language or group of dialects. There

4862-422: Is likely that an aircraft which is capable of shooting at an enemy machine will have the advantage. The most suitable weapon is a light, air-cooled machine-gun What was not generally agreed on was the superiority, at least for an attacking aircraft, of fixed forward-firing guns, aimed by pointing the aircraft at its target, rather than flexible weapons, aimed by a gunner other than the pilot. The idea of coupling

Russian is the language of 9% of the population according to the World Factbook. Ethnologue cites Russian as the country's de facto working language. In China , Russian has no official status, but it is spoken by the small Russian communities in the northeastern Heilongjiang and

5434-569: Is sometimes considered to have played a significant role in the formation of modern Russian. Also, Russian has notable lexical similarities with Bulgarian due to a common Church Slavonic influence on both languages, but because of later interaction in the 19th and 20th centuries, Bulgarian grammar differs markedly from Russian. Over the course of centuries, the vocabulary and literary style of Russian have also been influenced by Western and Central European languages such as Greek, Latin , Polish , Dutch , German, French, Italian, and English, and to

5577-576: Is spoken by 14.2% of the population according to an undated estimate from the World Factbook. In 2005, Russian was the most widely taught foreign language in Mongolia, and was compulsory in Year 7 onward as a second foreign language in 2006. Around 1.5 million Israelis spoke Russian as of 2017. The Israeli press and websites regularly publish material in Russian and there are Russian newspapers, television stations, schools, and social media outlets based in

5720-659: Is still commonly used as a lingua franca in Ukraine , Moldova , the Caucasus , Central Asia , and to a lesser extent in the Baltic states and Israel . Russian has over 258 million total speakers worldwide. It is the most spoken native language in Europe , the most spoken Slavic language , as well as the most geographically widespread language of Eurasia . It is the world's seventh-most spoken language by number of native speakers , and

Stress marks are mandatory in lexical dictionaries and books for children or Russian learners. The Russian syllable structure can be quite complex, with both initial and final consonant clusters of up to four consecutive sounds. Using

Initial trials indicated that the deflector wedges would not be sufficiently strong to cope with the standard steel-jacketed German ammunition, and representatives from Fokker and Pfalz, two companies already building Morane copies (although, strangely, not Schneider's LVG concern) were invited to Döberitz to inspect

6149-461: The 2011 Lithuanian census , Russian was the native language for 7.2% of the population. In Moldova , Russian was considered to be the language of interethnic communication under a Soviet-era law. On 21 January 2021, the Constitutional Court of Moldova declared the law unconstitutional and deprived Russian of the status of the language of interethnic communication. 50% of the population

6292-966: The Apollo–Soyuz mission, which first flew in 1975. In March 2013, Russian was found to be the second-most used language on websites after English. Russian was the language of 5.9% of all websites, slightly ahead of German and far behind English (54.7%). Russian was used not only on 89.8% of .ru sites, but also on 88.7% of sites with the former Soviet Union domain .su . Websites in former Soviet Union member states also used high levels of Russian: 79.0% in Ukraine, 86.9% in Belarus, 84.0% in Kazakhstan, 79.6% in Uzbekistan, 75.9% in Kyrgyzstan and 81.8% in Tajikistan. However, Russian

Among 12% of the population who grew up in

6578-582: The Fokker Scourge . The German high command was protective of the synchronizer system, instructing pilots not to venture over enemy territory in case they were forced down and the secret revealed, but the basic principles involved were already common knowledge, and by the middle of 1916 several Allied synchronizers were already available in quantity. By this time, the Fokker Stangensteuerung gear, which had worked reasonably well for synchronizing

6721-610: The German D-type scouts starting with the Albatros D.I . From the appearance of the Sopwith Camel and the SPAD S.XIII in mid-1917, right through to the end of gun synchronization in the 1950s, a twin gun installation was the international norm. Having the two guns firing simultaneously would obviously not have been a satisfactory arrangement. The guns needed to both fire at the same point on

6864-536: The Lewis gun and the Italian Revelli ) were triggered from an open bolt , with an unpredictable interval between triggering and firing, and were thus not suitable for synchronization without extensive modification. In practice it was found necessary for the gun to be fired in semi-automatic mode. As the propeller revolved, a series of firing impulses was transmitted to the gun, each of which could trigger it to fire

7007-575: The Ukrainian language in more than 30 spheres of public life: in particular in public administration , media, education, science, culture, advertising, services . The law does not regulate private communication. A poll conducted in March 2022 by RATING in the territory controlled by Ukraine found that 83% of the respondents believe that Ukrainian should be the only state language of Ukraine. This opinion dominates in all macro-regions, age and language groups. On

Russian is one of the official languages (or has similar status and interpretation must be provided into Russian) of the following: The Russian language is also one of two official languages aboard the International Space Station – NASA astronauts who serve alongside Russian cosmonauts usually take Russian language courses. This practice goes back to

7293-508: The 20th century, Russian was a mandatory language taught in the schools of the members of the old Warsaw Pact and in other countries that used to be satellites of the USSR. According to the Eurobarometer 2005 survey, fluency in Russian remains fairly high (20–40%) in some countries, in particular former Warsaw Pact countries. In Armenia , Russian has no official status, but it is recognized as

7579-519: The Great and developed from the Moscow ( Middle or Central Russian ) dialect substratum under the influence of some of the previous century's Russian chancery language. Prior to the Bolshevik Revolution , the spoken form of the Russian language was that of the nobility and the urban bourgeoisie. Russian peasants, the great majority of the population, continued to speak in their own dialects. However,

7722-578: The Institute of Russian Language of the Russian Academy of Sciences, an optional acute accent ( знак ударения ) may, and sometimes should, be used to mark stress . For example, it is used to distinguish between otherwise identical words, especially when context does not make it obvious: замо́к ( zamók – "lock") – за́мок ( zámok – "castle"), сто́ящий ( stóyashchy – "worthwhile") – стоя́щий ( stoyáshchy – "standing"), чудно́ ( chudnó – "this

Therefore, the Russian language is the seventh-largest in the world by the number of speakers , after English, Mandarin, Hindi -Urdu, Spanish, French, Arabic, and Portuguese. Russian is one of the six official languages of

8008-550: The Parabellum gun, synchronized with the first version of the Fokker gear. This prototype gear had such a short life that a redesign was necessary, producing the second, more familiar, production form of the gear. The gear used in the production Eindecker fighters replaced the oil pump's mechanical driveshaft-based system with a large cam wheel, almost a light flywheel, driven directly from the spinning rotary engine's crankcase . The push rod now took its reciprocating motion directly from

8151-807: The Russian alphabet include ⟨ ѣ ⟩ , which merged to ⟨ е ⟩ ( /je/ or /ʲe/ ); ⟨ і ⟩ and ⟨ ѵ ⟩ , which both merged to ⟨ и ⟩ ( /i/ ); ⟨ ѳ ⟩ , which merged to ⟨ ф ⟩ ( /f/ ); ⟨ ѫ ⟩ , which merged to ⟨ у ⟩ ( /u/ ); ⟨ ѭ ⟩ , which merged to ⟨ ю ⟩ ( /ju/ or /ʲu/ ); and ⟨ ѧ ⟩ and ⟨ ѩ ⟩ , which later were graphically reshaped into ⟨ я ⟩ and merged phonetically to /ja/ or /ʲa/ . While these older letters have been abandoned at one time or another, they may be used in this and related articles. The yers ⟨ ъ ⟩ and ⟨ ь ⟩ originally indicated

The formation of the unified and centralized Russian state in the 15th and 16th centuries, and the gradual re-emergence of a common political, economic, and cultural space created the need for a common standard language. The initial impulse for standardization came from

8437-506: The Saulnier patent, Fokker's gear was designed to actively fire the gun rather than interrupt it, and, like the later Vickers-Challenger gear developed for the RFC, it followed Saulnier in taking its primary mechanical drive from the oil pump of a rotary engine. The "transmission" between the motor and the gun was by a version of Saulnier's reciprocating push-rod. The main difference was that instead of

8580-454: The Soviet era can speak Russian, other generations of citizens that do not have any knowledge of Russian. Primary and secondary education by Russian is almost non-existent.

8866-497: The action of a semi-automatic weapon. It has been pointed out that this was a practical design that should have worked, but it did not. Apart from possible inconsistencies in the ammunition supplied, the real problem was that the gun used to trial the gear, a gas-operated Hotchkiss 8 mm (.323 in) machine gun borrowed from the French army, was fundamentally unsuitable for "semi-automatic" firing. Following initial unsuccessful tests,

9009-407: The advent of the constant-speed propeller , could vary widely, depending on the throttle setting and what maneuvers were being performed. Even if it had been feasible to pick a particular point on an aircraft engine's tachometer at which a machine gun's cyclic rate would permit it to fire through the propeller arc, this would be very limiting. It has been pointed out that any mechanism that achieved

9152-564: The aircraft, designated I-200 , was designed in the Polikarpov construction bureau. Work started in June 1939 , under the direction of Nikolai Polikarpov and his assistant M. Tetivikin. Polikarpov himself preferred radial engines and promoted his I-180 design at that time, but when the powerful Mikulin AM-37 inline engine became available, he decided to use it in a fighter. The approach that he selected

9295-481: The arc of the propeller, and even efforts, doomed to failure, to synchronize the Lewis Gun which was at the time the "standard" British aircraft weapon  – was the expedient of firing straight through the propeller arc and "hoping for the best". A high proportion of bullets would in the normal course pass the propeller without striking the blades, and each blade might typically take several hits before there

9438-406: The arc of the propeller. In the late 1930s, however, the main role of the fighter was increasingly seen as the destruction of large, all-metal bombers , for which this armament was inadequate. Since it was impractical to fit more than two guns in the limited space available in the front of a single-engine aircraft's fuselage , guns began to be mounted in the wings instead, firing outside the arc of

9581-404: The breech of the gun out of the pilot's reach for clearing jams. If the gun was mounted in the ideal position, within easy reach of the pilot, a much longer push rod was required, which tended to bend and break. The other problem was that the Stangensteuerung never worked well with more than one gun. Two (or even three) guns , mounted side by side and firing simultaneously , would have produced

9724-403: The broader sense of expanding the use of Russian alongside or in favour of other languages. The current standard form of Russian is generally regarded as the modern Russian literary language ( современный русский литературный язык – "sovremenny russky literaturny yazyk"). It arose at the beginning of the 18th century with the modernization reforms of the Russian state under the rule of Peter

9867-468: The canopy, an excessively hot cockpit and a "dangerous propensity to flick from a simple stall into a spin from which it was almost impossible to recover". A number of improvements were ordered to be made to the aircraft as a result of the deficiencies discovered during the trials, but only a few of them were able to be implemented before production began as the VVS was very anxious to get modern fighters into service. These included an additional air intake on

10010-523: The case of three guns, and was rather less than satisfactory, even for two. Most of the early Fokker and Halberstadt biplane fighters were limited to a single gun for this reason. In fact, the builders of the new Albatros twin-gunned stationary-engine fighters of late 1916 had to introduce their own synchronization gear, known as the Hedtke gear or Hedtkesteuerung , and it was evident that Fokker were going to have to come up with something radically new. This

10153-459: The controls. On 24 May the first prototype attained a speed of 648.5 km/h (402.9 mph) at 6,900 m (22,638 ft). It could not, however, attain the speed originally specified by the Air Force with this engine. The second prototype took to the air on 9 May, but the third aircraft, the first to be armed, was forced to wait until 6 June, as problems with its synchronization gear prolonged

10296-562: The country. There is an Israeli TV channel mainly broadcasting in Russian with Israel Plus . See also Russian language in Israel . Russian is also spoken as a second language by a small number of people in Afghanistan . In Vietnam , Russian has been added in the elementary curriculum along with Chinese and Japanese and were named as "first foreign languages" for Vietnamese students to learn, on equal footing with English. The Russian language

10439-405: The current historical consensus points to a synchronization device having been in development by Fokker's team (including engineer Heinrich Lübbe ) prior to the capture of Garros's machine. Whatever its ultimate source, the initial version of the Fokker synchronization gear (see illustration) very closely followed, not Schneider's patent, as claimed by Schneider and others, but Saulnier's . Like

10582-415: The deflector blades must have put undesirable stress on the engine's crankshaft. On 1 April 1915 Garros shot down his first German aircraft, killing both the crew. On 18 April 1915, after two more victories, Garros was forced down (by ground fire) behind German lines. Although he was able to burn his aircraft, Garros was captured and his special propeller was sufficiently intact to be sent for evaluation by

10725-675: The design was modified into the MiG-3 . The aircraft was issued to fighter regiments of the Soviet Air Forces (VVS) in 1941, but most were apparently destroyed during the opening days of Operation Barbarossa , the German invasion of the Soviet Union in June 1941. The MiG-1 was designed in response to a requirement for a high-altitude fighter with an inline engine issued by the VVS in January 1939. Initially

10868-459: The end of the First World War , German engineers were well on the way to perfecting a gear using an electrical rather than a mechanical or hydraulic link between the engine and the gun, with the gun triggered by an electro-mechanical solenoid . From 1918 to the mid-1930s the standard armament for a fighter aircraft remained two synchronized rifle-calibre machine guns , firing forward through

11011-413: The factory and the industrial plant their local peasant dialects with their phonetics, grammar, and vocabulary, and the very process of recruiting workers from peasants and the mobility of the worker population generate another process: the liquidation of peasant inheritance by way of leveling the particulars of local dialects. On the ruins of peasant multilingual, in the context of developing heavy industry,

11154-470: The failings of the first form of the gear had become clear, Fokker's team had adapted the new system to the new Parabellum MG14 machine gun, and fitted it to a Fokker M.5K , a type which was at the time serving in small numbers with the Fliegertruppen as the A.III. This aircraft, bearing IdFlieg serial number A.16/15 became the direct forerunner to the five M.5K/MG pre-production prototypes built, and

11297-414: The feat of firing between the whirling blades of a propeller without striking them could be described as "interrupting" the fire of the gun (to the extent that it no longer actually works as an automatic weapon at all), and also as "synchronizing", or "timing" its fire to coincide with the revolutions of the propeller. A typical synchronizing gear had three basic components. First, a method of determining

11440-451: The final reading amendments that state that all schools and kindergartens in the country are to transition to education in Latvian . From 2025, all children will be taught in Latvian only. On 28 September 2023, Latvian deputies approved The National Security Concept, according to which from 1 January 2026, all content created by Latvian public media (including LSM ) should be only in Latvian or

11583-448: The firing impulses were sometimes timed to occur at every two or three revolutions of the propeller, or, especially in the case of hydraulic or electric gears, at the rate of two or more for each revolution. The diagrams in this section assume, for simplicity's sake, one impulse for one revolution, so that each synchronized round is "aimed" at a single spot on the propeller disc. The timing of each impulse had to be adjusted to coincide with

11726-450: The firing mechanism to the propeller's rotation is an affectation. The objection is the same as to any gun position which is fixed along the longitudinal axis of the aircraft: the pilot is forced to fly directly at the enemy in order to fire. Under certain circumstances this is highly undesirable. As late as 1916, pilots of the DH.2 pusher fighter had problems convincing their senior officers that

11869-542: The first 100 I-200s were designated as the MiG-1 (after the initials of Mikoyan and Gurevich). The improvement process continued throughout the production run, though they were not immediately implemented in the production line, but were instead incorporated in a fourth prototype for evaluation. This aircraft first flew on 29 October 1940 and was a significant improvement over the I-200s then in production. It passed its State acceptance trials and its improvements were incorporated in

12012-569: The first practical – if far from reliable – gear to enter operational service was that fitted to the Fokker Eindecker fighters , which entered squadron service with the German Air Service in mid-1915. The success of the Eindecker led to numerous gun synchronization devices, culminating in the reasonably reliable hydraulic British Constantinesco gear of 1917. By

12155-415: The form of steel wedges which deflected the bullets which might otherwise have damaged the propeller, or ricocheted dangerously. Garros himself and his personal mechanic Jules Hue are sometimes credited with testing and perfecting the "deflectors". This crude system worked after a fashion, although the wedges diminished the propeller's efficiency, and the not inconsiderable force of the impact of bullets on

12298-426: The forward-firing armament of their aircraft was more effective if it was fixed to fire forward rather than being flexible. On the other hand, August Euler had patented the idea of a fixed gun as early as 1910 – long before tractor aircraft became the norm, illustrating his patent with a diagram of a machine gun-armed pusher . Whether directly inspired by Euler's original patent or not, the first inventor to patent

12441-407: The gear pauses, or "interrupts" the fire of the gun at the point where one of the blades of the propeller passes in front of its muzzle. Even the relatively slowly revolving propellers of First World War aircraft, however, typically turned twice or even three times for each shot a contemporary machine gun could fire. A two-bladed propeller would therefore obstruct the gun six times every firing cycle of

12584-617: The generation of immigrants who started arriving in the early 1960s). Only about 25% of them are ethnic Russians, however. Before the dissolution of the Soviet Union , the overwhelming majority of Russophones in Brighton Beach, Brooklyn in New York City were Russian-speaking Jews. Afterward, the influx from the countries of the former Soviet Union changed the statistics somewhat, with ethnic Russians and Ukrainians immigrating along with some more Russian Jews and Central Asians. According to

12727-480: The government bureaucracy for the lack of a reliable tool of communication in administrative, legal, and judicial affairs became an obvious practical problem. The earliest attempts at standardizing Russian were made based on the so-called Moscow official or chancery language, during the 15th to 17th centuries. Since then, the trend of language policy in Russia has been standardization in both the restricted sense of reducing dialectical barriers between ethnic Russians, and

12870-430: The ground firing tests. On 5 August 651 km/h (405 mph) was reached at 7,000 m (23,000 ft) using maximum boost. Time to altitude figures were 5.1 minutes to 5,000 m (16,000 ft) and 7.2 minutes to 7,000 m (23,000 ft) and speeds at lower altitudes were 579 km/h (360 mph) at 2,200 m (7,200 ft) and 605 km/h (376 mph) at 3,630 m (11,910 ft). The I-200

13013-601: The gun had to be returned, and the experiments ceased. When the pilots of the British Royal Flying Corps and Royal Naval Air Service arrived in France in 1914, they were equipped with pusher aircraft too underpowered to carry machine guns and still have a chance of overtaking the enemy, and tractor aircraft which were difficult to arm effectively because the propeller was in the way. Among other attempts to get around this – such as firing obliquely past

13156-407: The gun is situated at the engine (driven in this case by the same spindle that operated the oil pump and the tachometer) and the impulses themselves are transmitted by a reciprocating rod rather than Schneider's rotating shaft. The idea of literally "interrupting" the firing of the gun gives way (probably as the result of experience) to the principle of pulling the trigger for each successive shot, like

13299-423: The gun was fired through the propeller with no control at all. The other main type of failure resulted in fewer or no firing impulses, usually due to the generator or linkages either jamming or breaking. This was a common cause of synchronized guns "jamming". The speed of the propeller, and thus the distance that it travelled between the firing of the gun and the arrival of the bullet at the propeller disc, varied as

13442-419: The gun, a four-bladed one twelve times. A gun set up this way would be interrupted more than forty times per second, while firing at only around seven rounds per second. Unsurprisingly, the designers of so-called interrupter gears found this too problematic to be seriously attempted, as the gaps between "interruptions" would have been too short to allow the gun to fire at all. True synchronization, though, with

13585-546: The gun. The firing button for the gun simply engaged a clutch at the engine which set the flexible drive (and thus the trigger motor) in motion. In some ways this brought the new gear closer to the original Schneider patent (q.v.) . A major advantage was that the adjustment (to set where on the propeller's disc each bullet was to impact) was now in the gun itself. This meant that each gun was adjusted separately, an important feature, since twin synchronized guns were not set to be fired in strict unison, but when they were pointing at

13728-515: The main units inwards into the wing center section. The cockpit was situated well aft, which seriously limited forward vision when landing and taxiing . The AM-37 engine was not yet available and the less powerful V-12 Mikulin AM-35 A had to be substituted. It had six exhaust ejectors, one for each pair of cylinders, that provided some additional thrust. It drove a VISh-22Ye controllable-pitch propeller 3 metres (9.8 ft) in diameter. The air intakes for

13871-473: The mechanism and suggest ways that its action might be duplicated. Anthony Fokker was able to persuade Idflieg to arrange the loan of a Parabellum machine gun and ammunition so that his device could be tested, and for these items to be transported forthwith to the Fokker Flugzeugwerke GmbH at Schwerin (although probably not in his railway compartment or "under his arm", as he claimed after

14014-409: The nature of the round. The "trigger motor" could theoretically take two forms. The earliest patent (Schneider 1913) assumed that the synchronization gear would periodically prevent the gun from firing , thus operating as a true, or literal "interrupter". In practice all "real-life" synchronization gears, for which we have reliable technical details, directly fired the gun : operating it as if it were

14157-516: The northwestern Xinjiang Uyghur Autonomous Region . Russian was also the main foreign language taught in school in China between 1949 and 1964. In Kazakhstan , Russian is not a state language, but according to article 7 of the Constitution of Kazakhstan its usage enjoys equal status to that of the Kazakh language in state and local administration. The 2009 census reported that 10,309,500 people, or 84.8% of

14300-515: The other hand, before the war, almost a quarter of Ukrainians were in favour of granting Russian the status of the state language, while after the beginning of Russia's invasion the support for the idea dropped to just 7%. In peacetime, the idea of raising the status of Russian was traditionally supported by residents of the south and east . But even in these regions, only a third of the respondents were in favour, and after Russia's full-scale invasion , their number dropped by almost half. According to

14443-455: The other three languages in the East Slavic branch. In many places in eastern and southern Ukraine and throughout Belarus, these languages are spoken interchangeably, and in certain areas traditional bilingualism resulted in language mixtures such as Surzhyk in eastern Ukraine and Trasianka in Belarus. An East Slavic Old Novgorod dialect , although it vanished during the 15th or 16th century,

14586-446: The parliament approved a bill to close up all Russian language schools and kindergartens by the school year. The transition to only Estonian language schools and kindergartens will start in the 2024-2025 school year. In Latvia , Russian is officially considered a foreign language. 55% of the population was fluent in Russian in 2006, and 26% used it as the main language with family, friends, or at work. On 18 February 2012, Latvia held

14729-453: The peasants' speech was never systematically studied, as it was generally regarded by philologists as simply a source of folklore and an object of curiosity. This was acknowledged by the noted Russian dialectologist Nikolai Karinsky , who toward the end of his life wrote: "Scholars of Russian dialects mostly studied phonetics and morphology. Some scholars and collectors compiled local dictionaries. We have almost no studies of lexical material or

However, one was still in the inventory of the VVS as late as 1944 when it was recorded as withdrawn that year.

15015-455: The population aged 15 and above, could read and write well in Russian, and understand the spoken language. In October 2023, Kazakhstan drafted a media law aimed at increasing the use of the Kazakh language over Russian, the law stipulates that the share of the state language on television and radio should increase from 50% to 70%, at a rate of 5% per year, starting in 2025. In Kyrgyzstan , Russian

15158-418: The population was fluent in Russian in 2006, and 67% used it as the main language with family, friends, or at work. According to the 2019 Belarusian census , out of 9,413,446 inhabitants of the country, 5,094,928 (54.1% of the total population) named Belarusian as their native language, with 61.2% of ethnic Belarusians and 54.5% of ethnic Poles declaring Belarusian as their native language. In everyday life in

15301-404: The position of the propeller at a given instant was required. Typically, a cam , driven either directly from the propeller shaft itself, or from some part of the drive train revolving at the same speed as the propeller, generated a series of impulses at the same rate as the propeller's revolutions. There were exceptions to this. Some gears placed the cam within the gun trigger mechanism itself, and

The third prototype was generally used for armament trials, experimenting with 82 mm (3.2 in) RS-82 rockets among other weapons. For another trial it was equipped with the experimental 23 mm (0.91 in) MP-3 autocannon carried underneath the wings in external pods and redesignated as the IP-201. The 12.7 mm UBS gun

15587-442: The production line from the 101st I-200. These were designated as the MiG-3 on 9 December, although the first production MiG-3 was not completed until 20 December 1940. The I-200 prototypes were used to evaluate a number of proposals. For example, the second prototype was fitted with a prototype of the AM-37 engine and first flew with that engine on 6 January 1941. It experienced severe vibration problems and, despite efforts to cure

15730-475: The pronunciation of ultra-short or reduced /ŭ/ , /ĭ/ . Because of many technical restrictions in computing and also because of the unavailability of Cyrillic keyboards abroad, Russian is often transliterated using the Latin alphabet. For example, мороз ('frost') is transliterated moroz , and мышь ('mouse'), mysh or myš' . Once commonly used by the majority of those living outside Russia, transliteration

15873-505: The propeller disc , which means that one had to fire a tiny fraction of a second later than the other. This is why early gears designed for a single machine gun needed to be modified in order to control two guns satisfactorily. In practice, at least part of the mechanism had to be duplicated, even if the two weapons were not synchronized separately. From the beginnings of practical flight, possible military uses for aircraft were considered, although not all writers came to positive conclusions on

16016-455: The propeller so not requiring synchronising. Synchronizing became unnecessary on all aircraft with the introduction of propellerless jet propulsion . A mechanism to enable an automatic weapon to fire between the blades of a whirling propeller is usually called an interrupter or synchronizer gear. Both these terms are more or less misleading, at least insofar as explaining what happens when the gear functions. The term "interrupter" implies that

16159-466: The proper pronunciation of uncommon words or names. Russian is an East Slavic language of the wider Indo-European family . It is a descendant of Old East Slavic , a language used in Kievan Rus' , which was a loose conglomerate of East Slavic tribes from the late 9th to the mid-13th centuries. From the point of view of spoken language , its closest relatives are Ukrainian , Belarusian , and Rusyn ,

16302-409: The push rod passing directly from the engine to the gun itself, which would have required a tunnel through the firewall and fuel tank (as shown in the Saulnier patent drawings), it was driven by a shaft joining the oil pump to a small cam at the top of the fuselage. This eventually proved unsatisfactory, as the oil pump's mechanical drive spindle was insufficiently robust to take the extra load. Before

16445-410: The question of synchronization. Early synchronized guns of the 1915–1917 period had a rate of fire in the region of 400 rounds per minute. At this comparatively leisurely rate of fire a synchronizer can be geared down to deliver a single firing impulse every two or three turns of the propeller, rendering it more reliable without unduly slowing the rate of fire. To control a faster gun, with, for example,

16588-491: The rate of engine revolutions changed. Where muzzle velocity was very high, and the guns were sited well forward so that the bullets had a very short distance to reach the disc of the propeller, this difference could be largely ignored. But in the case of relatively low muzzle velocity weapons, or any gun sited well back from the propeller, the question could become critical, and in some cases the pilot had to consult his tachometer, taking care that his engine revolutions were within

16731-565: The rate of fire in comparison with a free-firing machine gun, which fires the moment it is ready to do so; but provided the gear functioned correctly, the gun could fire fairly rapidly between the whirling propeller blades without striking them. Some other machine-guns, such as the Austrian Schwarzlose and the American Marlin , proved less than perfectly adapted to synchronization, although eventually predictable "single shot" firing

16874-449: The rear fuselage was made from wood, but the front fuselage, from the propeller to the rear of the cockpit, was a welded steel tube truss covered by duralumin . The bulk of the wing was wooden, but the center section was all-metal with a steel I-section main spar . The wing used a Clark Y H profile. It was evenly tapered with rounded tips and the outer wing panels had 5° of dihedral . All three landing gear wheels retracted hydraulically;

17017-491: The respondents), while according to the 2002 census – 142.6 million people (99.2% of the respondents). In Ukraine , Russian is a significant minority language. According to estimates from Demoskop Weekly, in 2004 there were 14,400,000 native speakers of Russian in the country, and 29 million active speakers. 65% of the population was fluent in Russian in 2006, and 38% used it as the main language with family, friends, or at work. On 5 September 2017, Ukraine's Parliament passed

17160-481: The starboard side of the nose for the oil cooler, rubber sheaths around the fuel tanks to make them self-sealing , two underwing bomb racks each capable of carrying a 100-kilogram (220 lb) FAB-100 bomb, a PBP-1 gunsight and each ShKAS was given 375 rounds and the UBS 300 rounds. From the ninth aircraft onwards the side-opening canopy was replaced by a rear-sliding canopy that could be jettisoned in flight. On 9 December 1940

17303-486: The subject. By 1913, military exercises in Britain, Germany, and France had confirmed the likely usefulness of aircraft for reconnaissance and surveillance, and this was seen by a few forward looking officers as implying the need to deter or destroy the enemy's reconnaissance machines. Thus aerial combat was by no means entirely unanticipated, and the machine gun was from the first seen as the most likely weapon to be used. It

17446-567: The supercharger were in the wing roots and the oil cooler was on the port side of the engine cowling. The radiator was underneath the cockpit. Armament included two fuselage-mounted 7.62 mm (0.300 in) ShKAS machine guns and one 12.7 mm (0.50 in) UBS machine gun . The result was a highly conventional aircraft that first flew on schedule on 5 April 1940 at the Khodynka Aerodrome in Moscow with chief test pilot Arkadij Ekatov at

17589-675: The survey carried out by RATING in August 2023 in the territory controlled by Ukraine and among the refugees, almost 60% of the polled usually speak Ukrainian at home, about 30% – Ukrainian and Russian, only 9% – Russian. Since March 2022, the use of Russian in everyday life has been noticeably decreasing. For 82% of respondents, Ukrainian is their mother tongue, and for 16%, Russian is their mother tongue. IDPs and refugees living abroad are more likely to use both languages for communication or speak Russian. Nevertheless, more than 70% of IDPs and refugees consider Ukrainian to be their native language. In

17732-459: The syntax of Russian dialects." After 1917, Marxist linguists had no interest in the multiplicity of peasant dialects and regarded their language as a relic of the rapidly disappearing past that was not worthy of scholarly attention. Nakhimovsky quotes the Soviet academicians A.M Ivanov and L.P Yakubinsky, writing in 1930: The language of peasants has a motley diversity inherited from feudalism. On its way to becoming proletariat peasantry brings to

17875-462: The target in his sights for a fleeting moment, so a concentration of bullets was vital for achieving a "kill". Even flimsy First World War aircraft often took a surprisingly large number of hits to shoot down, and later, larger aircraft were even harder propositions. There were two obvious solutions – to fit a more efficient gun with a higher cyclic rate of fire , or increase the number of guns carried. Both of these measures impinged on

18018-463: The time. The exact form of the synchronization gear fitted to Schneider's LVG E.I of 1915 and its relationship to this patent is unknown, since no plans survive. Unlike the Schneider patent design, Saulnier's device was actually built, and may be considered the first practical synchronization gear to be tested. For the first time, the cam producing the to-and-fro movement conveying firing impulses to

18161-477: The two had to operate. In practice, all known gears worked on the principle of actively triggering each shot, in the manner of a semi-automatic weapon . Design and experimentation with gun synchronization had been underway in France and Germany in 1913–1914, following the ideas of August Euler , who seems to have been the first to suggest mounting a fixed armament firing in the direction of flight (in 1910). However,

18304-770: The two. Others divide the language into three groupings, Northern , Central (or Middle), and Southern , with Moscow lying in the Central region. The Northern Russian dialects and those spoken along the Volga River typically pronounce unstressed /o/ clearly, a phenomenon called okanye ( оканье ). Besides the absence of vowel reduction, some dialects have high or diphthongal /e⁓i̯ɛ/ in place of Proto-Slavic  * ě and /o⁓u̯ɔ/ in stressed closed syllables (as in Ukrainian) instead of Standard Russian /e/ and /o/ , respectively. Another Northern dialectal morphological feature

18447-506: The use of the language has some presence in certain areas. A large part of the population, especially the older generations, can speak Russian as a foreign language. However, English has replaced Russian as lingua franca in Lithuania and around 80% of young people speak English as their first foreign language. In contrast to the other two Baltic states, Lithuania has a relatively small Russian-speaking minority (5.0% as of 2008). According to

18590-487: The war). The story of his conception, development and installation of the Fokker synchronization device in a period of 48 hours (first found in an authorised biography of Fokker written in 1929) is not now believed to be factual. Another possible explanation is that Garros's Morane, partly destroyed by fire as it was, had sufficient traces of the original synchronization gear remaining for Fokker to have guessed how it worked. For various reasons this also seems unlikely, and

18733-682: The world's ninth-most spoken language by total number of speakers . Russian is one of two official languages aboard the International Space Station , one of the six official languages of the United Nations , as well as the fourth most widely used language on the Internet . Russian is written using the Russian alphabet of the Cyrillic script ; it distinguishes between consonant phonemes with palatal secondary articulation and those without—the so-called "soft" and "hard" sounds. Almost every consonant has

18876-589: Was achieved, typically by modifying the trigger mechanism to emulate "closed bolt" firing. Most weapons that were successfully synchronized (at least in the First World War period) were (like the German Parabellum and Spandau guns and the British Vickers ) based on the original Maxim gun of 1884, a closed bolt weapon operated by barrel recoil. Before these distinctions were fully understood, much time

19019-407: Was designed in late 1916 and took the form of a new synchronization gear without any rods at all. The cam that generated the firing impulses was moved from the engine to the gun; the trigger motor in effect now generated its own firing impulses. The linkage between the propeller and the gun now consisted of a flexible drive shaft directly connecting the end of the engine camshaft to the trigger motor of

19162-563: Was effectively the prototype of the Fokker E.I – the first production single-seat fighter aircraft armed with a synchronized machine gun. This prototype was demonstrated to IdFlieg by Fokker in person on 19–20 May 1915 at the Döberitz proving ground near Berlin. Leutnant Otto Parschau was test flying this aircraft by 30 May 1915. The five production prototypes (factory designated M.5K/MG and serialed E.1/15 – E.5/15 ) were undergoing military trials shortly thereafter. These were all armed with

19305-405: Was first introduced in North America when Russian explorers voyaged into Alaska and claimed it for Russia during the 18th century. Although most Russian colonists left after the United States bought the land in 1867, a handful stayed and preserved the Russian language in this region to this day, although only a few elderly speakers of this unique dialect are left. In Nikolaevsk, Alaska , Russian

19448-421: Was fluent in Russian in 2006, and 19% used it as the main language with family, friends, or at work. According to the 2014 Moldovan census , Russians accounted for 4.1% of Moldova's population, 9.4% of the population declared Russian as their native language, and 14.5% said they usually spoke Russian. According to the 2010 census in Russia , Russian language skills were indicated by 138 million people (99.4% of

19591-499: Was much danger of its failing, especially if it were bound with tape to prevent splintering (see diagram below, and illustration to the left). After his early synchronization experiments failed, Saulnier pursued a method trusting rather less to statistics and luck by developing armoured propeller blades that would resist damage. By March 1915, when French pilot Roland Garros approached Saulnier to arrange for this device to be installed on his Morane-Saulnier Type L , these had taken

19734-508: Was ordered into production almost immediately, on 31 May 1940. In contrast to the other competing designs, the I-26 ( Yak-1 ) and I-301 ( LaGG-3 ), the I-200 successfully completed the state trials in August on its first attempt. But the trials revealed a number of serious defects, including inadequate visibility when taxiing, poor-quality plexiglas in the canopy obscuring the pilot's view, heavy controls, poor longitudinal stability, difficulty in opening

19877-540: Was removed for these tests and the space freed up was used to install an extra fuel tank. Initially the cannon had the low rate of fire of only 300 rounds per minute, but this was soon doubled and the gun was renamed the MP-6. Installation of the guns was difficult, despite the aircraft's metal outer wing panels, and the wings deformed when the cannon were first mounted. It made its first and only flight on 1 December 1940 carrying two MP-6s and two 12.7 mm AP-12.7 machine guns, but

20020-402: Was the sixth-most used language on the top 1,000 sites, behind English, Chinese, French, German, and Japanese. Despite leveling after 1900, especially in matters of vocabulary and phonetics, a number of dialects still exist in Russia. Some linguists divide the dialects of Russian into two primary regional groupings, "Northern" and "Southern", with Moscow lying on the zone of transition between

20163-519: Was to build the smallest possible aircraft around the intended powerplant, thereby minimizing weight and drag — the philosophy of the light fighter .
