The Central Aerohydrodynamic Institute (also ( Zhukovsky ) Central Institute of Aerodynamics , Russian : Центра́льный аэрогидродинами́ческий институ́т, ЦАГИ , romanized :  Tsentral'nyy Aerogidrodinamicheskiy Institut , TsAGI ) is a Russian national research centre for aviation . It was founded in Moscow by Russian aviation pioneer Nikolai Yegorovich Zhukovsky on December 1, 1918.

51-665: From 1925 and up to the 1930s, TsAGI developed and hosted Tupolev 's AGOS ( Aviatziya, Gidroaviatziya i Opytnoye Stroitelstvo , the "Aviation, Hydroaviation, and Experimental Construction"), the first aircraft design bureau in Soviet Union, and at the time the main one. In 1930, two other major aircraft design bureaus in the country were the Ilyushin 's TsKB ( Tsentralnoye Konstruksionnoye Byuro means "Central Design Bureau") and an independent, short-lived Kalinin 's team in Kharkiv . In 1935 TsAGI

102-469: A wind tunnel which led to the formation of an aerodynamic laboratory at IMTU. In 1911, Tupolev was accused of taking part in revolutionary activities, including demonstrations and distribution of subversive literature, and was arrested. Tupolev was later released on condition that he return to his family home in Pustomazovo. Tupolev was only allowed to return to IMTU in 1914, studying during World War I and

153-623: A calendar change, respectively. Usually, they refer to the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and 1923. In England , Wales , Ireland and Britain's American colonies , there were two calendar changes, both in 1752. The first adjusted the start of a new year from 25 March ( Lady Day , the Feast of the Annunciation ) to 1 January,

204-535: A change which Scotland had made in 1600. The second discarded the Julian calendar in favour of the Gregorian calendar, skipping 11 days in the month of September to do so. To accommodate the two calendar changes, writers used dual dating to identify a given day by giving its date according to both styles of dating. For countries such as Russia where no start-of-year adjustment took place, O.S. and N.S. simply indicate

255-454: A letter dated "12/22 Dec. 1635". In his biography of John Dee , The Queen's Conjurer , Benjamin Woolley surmises that because Dee fought unsuccessfully for England to embrace the 1583/84 date set for the change, "England remained outside the Gregorian system for a further 170 years, communications during that period customarily carrying two dates". In contrast, Thomas Jefferson , who lived while

306-509: A prison to an NKVD sharashka for aircraft designers in Bolshevo near Moscow, where many surviving ex-TsAGI people had already been sent to work. The sharashka soon moved to Moscow and was dubbed "Tupolevka" after Tupolev, its most prominent inmate. In 1940, Tupolev was tried and convicted with a ten-year sentence, and during this time he developed the Tupolev Tu-2 which would become one of

357-878: A start-of-year adjustment works well with little confusion for events before the introduction of the Gregorian calendar. For example, the Battle of Agincourt is well known to have been fought on 25 October 1415, which is Saint Crispin's Day . However, for the period between the first introduction of the Gregorian calendar on 15 October 1582 and its introduction in Britain on 14 September 1752, there can be considerable confusion between events in Continental Western Europe and in British domains. Events in Continental Western Europe are usually reported in English-language histories by using

408-579: A village near the city of Kimry in Tver Governorate , Russian Empire , the sixth of seven children born to his Russian parents. Tupolev's father, Nikolai Ivanovich Tupolev (1842-1911), was a native of Surgut , who worked as a notary for the governorate. Nikolai had studied law at St. Petersburg University , but was expelled after the assassination of Alexander II for his ties to revolutionaries despite not being involved in their actions. Tupolev's mother, Anna Vasilievna ( née Lisitsyna) (1850-1928)

459-526: Is 9 February 1649, the date by which his contemporaries in some parts of continental Europe would have recorded his execution. The O.S./N.S. designation is particularly relevant for dates which fall between the start of the "historical year" (1 January) and the legal start date, where different. This was 25 March in England, Wales, Ireland and the colonies until 1752, and until 1600 in Scotland. In Britain, 1 January

Andrei Tupolev Andrei Nikolayevich Tupolev ( Russian : Андрей Николаевич Туполев ; 10 November [ O.S. 29 October] 1888 – 23 December 1972) was a Russian and later Soviet aeronautical engineer known for his pioneering aircraft designs as

561-563: Is about the life and works of Tupolev and Igor Sikorsky , the Russian-American aviation pioneer. Prospekt Tupoleva, the main avenue in the Aviatsionny microdistrict of Domodedovo located next to Domodedovo Airport , was named after Tupolev. A memorial mural of Tupolev was painted on the side of the 20 Prospekt Tupoleva apartment building. In 2018, Vnukovo International Airport in Moscow

612-670: The Buran space shuttle and the Tu-2000 long-range heavy bomber. Tupolev was never a member of the Communist Party of the Soviet Union despite his status and being elected to several deputy positions. List (partial) of retired or active aircraft designed or made by aviation designer/engineer Andrei Tupolev; incl. both military and civilian planes, jets and other aircraft: Old Style and New Style dates Old Style ( O.S. ) and New Style ( N.S. ) indicate dating systems before and after

663-813: The Eastern Bloc were named in honour of Tupolev, as well as one in Western Europe, the Tupolevlaan near Amsterdam Airport Schiphol . In 1973, the Kazan Aviation Institute was named after Tupolev, and a monument of him was erected in Kazan in a public square at the intersection of Dekabristov, Gagarin and Korolev Streets. In 1979, a bust of Tupolev was erected at a public square in Kimry, near his birthplace Pustomazovo which no longer exists. Another memorial to Tupolev

714-660: The Emperor Nicholas II Moscow State University of Railway Engineering . Tupolev was accepted at both, but ultimately chose to attend at IMTU. In 1909, Tupolev began studying aerodynamics under the Russian aviation pioneer Nikolay Zhukovsky , and volunteered for the Aeronautical workshop ( Kruzhok ) headed by Zhukovsky. In 1910, together with his workshop friends, Tupolev built and test piloted his first glider . During his workshop days, Tupolev also built

765-592: The Russian Empire and the very beginning of Soviet Russia . For example, in the article "The October (November) Revolution", the Encyclopædia Britannica uses the format of "25 October (7 November, New Style)" to describe the date of the start of the revolution. The Latin equivalents, which are used in many languages, are, on the one hand, stili veteris (genitive) or stilo vetere (ablative), abbreviated st.v. , and meaning "(of/in) old style" ; and, on

816-885: The Russian Revolution . Tupolev completed his studies in 1918 and was awarded the degree of Engineer-Mechanic when he presented his thesis on the development of seaplanes . By 1920, the IMTU had been renamed the Moscow Higher Technical School (MVTU) and Tupolev was teaching a course there on the basics of aerodynamic calculations. Tupolev was a leading figure of the Moscow -based Central Aerohydrodynamic Institute (TsAGI; Russian : Центральный аэро-гидродинамический институт; ЦАГИ ) from 1929 until his death in 1972. The Central Design Office or TsKB ( Russian : Центральное конструкторское бюро; ЦКБ ) based there produced bombers for

867-506: The Soviet Air Force and some airliners , which in the years before World War II and especially in his 1930s-era designs, were based partially on the all-metal aircraft design concepts pioneered by Hugo Junkers . In 1925, Tupolev designed a twin-engine bomber, the TB-1 , which was considered one of the most advanced designs of the time. By 1934, Tupolev had led the design bureau that designed

918-454: The Tu-104 , the world's second operational production jet airliner . After Khruschev's removal from office in late 1964 and the rise of Leonid Brezhnev , the ageing Tupolev gradually lost positions at the centres of Soviet power to rivals in the aircraft industry. The prestigious Tu-144 programme enjoyed top level support until 1973, as did the important Tu-154 airliner, but the favored position

969-567: The reverse engineered Tu-4 . Tupolev was highly honoured in the Soviet Union and awarded various titles and honours including the Hero of Socialist Labor three times, Order of Lenin eight times, Order of the Red Banner of Labour two times, made an academician of the Russian Academy of Sciences in 1953, and a Colonel-General of the Soviet Air Force in 1968. Tupolev was also honoured outside

1020-532: The 4th century , had drifted from reality . The Gregorian calendar reform also dealt with the accumulated difference between these figures, between the years 325 and 1582, by skipping 10 days to set the ecclesiastical date of the equinox to be 21 March, the median date of its occurrence at the time of the First Council of Nicea in 325. Countries that adopted the Gregorian calendar after 1699 needed to skip an additional day for each subsequent new century that

1071-579: The Boyne was commemorated with smaller parades on 1 July. However, both events were combined in the late 18th century, and continue to be celebrated as " The Twelfth ". Because of the differences, British writers and their correspondents often employed two dates, a practice called dual dating , more or less automatically. Letters concerning diplomacy and international trade thus sometimes bore both Julian and Gregorian dates to prevent confusion. For example, Sir William Boswell wrote to Sir John Coke from The Hague

1122-455: The British Isles and colonies converted to the Gregorian calendar, instructed that his tombstone bear his date of birth by using the Julian calendar (notated O.S. for Old Style) and his date of death by using the Gregorian calendar. At Jefferson's birth, the difference was eleven days between the Julian and Gregorian calendars and so his birthday of 2 April in the Julian calendar is 13 April in

1173-410: The British colonies, changed the start of the year from 25 March to 1 January, with effect from "the day after 31 December 1751". (Scotland had already made this aspect of the changes, on 1 January 1600.) The second (in effect ) adopted the Gregorian calendar in place of the Julian calendar. Thus "New Style" can refer to the start-of-year adjustment , to the adoption of the Gregorian calendar , or to

1224-612: The Gregorian calendar. For example, the Battle of Blenheim is always given as 13 August 1704. However, confusion occurs when an event involves both. For example, William III of England arrived at Brixham in England on 5 November (Julian calendar), after he had set sail from the Netherlands on 11 November (Gregorian calendar) 1688. The Battle of the Boyne in Ireland took place a few months later on 1 July 1690 (Julian calendar). That maps to 11 July (Gregorian calendar), conveniently close to

1275-466: The Gregorian calendar. Similarly, George Washington is now officially reported as having been born on 22 February 1732, rather than on 11 February 1731/32 (Julian calendar). The philosopher Jeremy Bentham , born on 4 February 1747/8 (Julian calendar), in later life celebrated his birthday on 15 February. There is some evidence that the calendar change was not easily accepted. Many British people continued to celebrate their holidays "Old Style" well into

1326-430: The Julian and Gregorian dating systems respectively. The need to correct the calendar arose from the realisation that the correct figure for the number of days in a year is not 365.25 (365 days 6 hours) as assumed by the Julian calendar but slightly less (c. 365.242 days). The Julian calendar therefore has too many leap years . The consequence was that the basis for the calculation of the date of Easter , as decided in

1377-564: The Julian calendar had added since then. When the British Empire did so in 1752, the gap had grown to eleven days; when Russia did so (as its civil calendar ) in 1918, thirteen days needed to be skipped. In the Kingdom of Great Britain and its possessions, the Calendar (New Style) Act 1750 introduced two concurrent changes to the calendar. The first, which applied to England, Wales, Ireland and

1428-510: The Julian date of the subsequent (and more decisive) Battle of Aughrim on 12 July 1691 (Julian). The latter battle was commemorated annually throughout the 18th century on 12 July, following the usual historical convention of commemorating events of that period within Great Britain and Ireland by mapping the Julian date directly onto the modern Gregorian calendar date (as happens, for example, with Guy Fawkes Night on 5 November). The Battle of

1479-576: The Soviet Union as an honorary member of the British Royal Aeronautical Society and the American Institute of Aeronautics and Astronautics in recognition of his work. In 2018, Vnukovo International Airport was formally renamed to Vnukovo Andrei Tupolev International Airport in his honour. Andrei Nikolayevich Tupolev was born on 10 November  [ O.S. 29 October] 1888 in Pustomazovo ( Russian : Пустомазово ),

1530-466: The Tupolev Design Bureau enjoyed through Tupolev's personal political connections was largely eclipsed by the Ilyushin aircraft manufacturing and design company. To his contemporaries, Tupolev was known as a witty but crude master of obscene vocabulary who invariably and energetically insisted on fast and adequate technical fixes at the expense of scholastic ideal solutions. A hallmark of Tupolev

1581-486: The combination of the two. It was through their use in the Calendar Act that the notations "Old Style" and "New Style" came into common usage. When recording British history, it is usual to quote the date as originally recorded at the time of the event, but with the year number adjusted to start on 1 January. The latter adjustment may be needed because the start of the civil calendar year had not always been 1 January and

1632-524: The director of the Tupolev Design Bureau . Tupolev was an early pioneer of aeronautics in Russia and served as a protégé of Nikolay Zhukovsky . Tupolev designed or oversaw the design of more than 100 types of civilian and military aircraft in the Soviet Union over 50 years, some of which set 78 world records . Tupolev produced many notable designs such as the Tu-2 , Tu-16 , Tu-95 , and Tu-104 , and

1683-533: The end of the following December, 1661/62 , a form of dual dating to indicate that in the following twelve weeks or so, the year was 1661 Old Style but 1662 New Style. Some more modern sources, often more academic ones (e.g. the History of Parliament ) also use the 1661/62 style for the period between 1 January and 24 March for years before the introduction of the New Style calendar in England. The Gregorian calendar

1734-515: The first aircraft to deliver a nuclear weapon . The Soviet Union had repeatedly asked for B-29s through the World War II Lend Lease program but these requests were all denied by the US. Tupolev succeeded in the complex task of re-engineering the design with Russian engines, weapons, equipment and airfoil sections, while using available metric sheetmetal which required a nearly complete redesign as

1785-458: The following years, Tupolev overcame competition from Vladimir Myasishchev and his M-4 series of jet-powered strategic bombers, to get the Tu-16 design into service. This was in part thanks to Tupolev's close rapport with Nikita Khrushchev , the new leader of the Soviet Union who had denounced Stalin's terror, of which Tupolev had been a victim. At about the same time, Tupolev introduced into service

1836-519: The largest aircraft flying in the world at the time, the 63-meter wingspan, eight-engined Maksim Gorki , again built with the Junkers metal structure airframe concepts. In 1937, an improved version of the earlier TB-1, the four-engined TB-3 , made a landing at the North Pole . As the number of qualified aircraft designers increased, Tupolev set up his own office, producing a number of designs designated with

1887-712: The most important aircraft of World War II. Tupolev was released in July 1941 around the time of the German invasion of the Soviet Union to "conduct important defence work" but was not fully rehabilitated by the Soviet state until 1955, two years after Joseph Stalin 's death. Tupolev headed the B-4 project, as it was initially designated, to reverse engineer the American Boeing B-29 Superfortress strategic bomber, which had been

1938-507: The multiple illegal American overflights, mostly with Martin PBM-5 Mariners that had already begun, and the overt threat of nuclear attack. Tupolev had several examples of the resulting Tu-4 flying in time for the 1947 May Day parade. By the time of his rehabilitation on 9 April 1955, Tupolev had designed and was about to start testing his unique turboprop strategic bomber, the Tu-95 . In

1989-418: The original had been built to imperial measurements, while new alloys also had to be brought into production. They used four B-29s which had come down in Soviet controlled territory as references, after having sustained light damage while bombing Japan in 1945. Tupolev's own design for the role had been ignored in the interest of getting the new long range bomber into service as rapidly as possible to respond to

2040-452: The other, stili novi or stilo novo , abbreviated st.n. and meaning "(of/in) new style". The Latin abbreviations may be capitalised differently by different users, e.g., St.n. or St.N. for stili novi . There are equivalents for these terms in other languages as well, such as the German a.St. (" alter Stil " for O.S.). Usually, the mapping of New Style dates onto Old Style dates with

2091-533: The outline of a Tu-144 taking off. Tupolev was married to Yuliya Nikolaevna Tupoleva (née Zheltyakova) until her death in 1962. Tupolev's daughter Yuliya (1920–2011) was a doctor who was awarded the title of Honored Doctor of the Russian Federation. Tupolev's son Alexei (1925-2001) was a successful pioneering aircraft designer who designed the Tupolev Tu-144 supersonic passenger jet, and helped design

2142-573: The prefix ANT ( Russian : АНТ ) from his initials. However, on 21 October 1937, Tupolev was arrested together with Vladimir Petlyakov and the entire directorate of the TsAGI and EDO during the Great Purge on trumped up charges of sabotage , espionage and of aiding the Russian Fascist Party . Many of his colleagues were executed but Tupolev himself was imprisoned. In 1939, Tupolev was moved from

2193-474: Was altered at different times in different countries. From 1155 to 1752, the civil or legal year in England began on 25 March ( Lady Day ); so for example, the execution of Charles I was recorded at the time in Parliament as happening on 30 January 164 8 (Old Style). In newer English-language texts, this date is usually shown as "30 January 164 9 " (New Style). The corresponding date in the Gregorian calendar

2244-680: Was born in Torzhok in the family of a judicial investigator, and graduated from the Mariinsky Gymnasium in Tver . Anna's parents purchased the small estate in Pustomazovo where Tupolev was born. After first being educated at home, Tupolev studied at the Gymnasium in Tver and finished in 1908. Tupolev then applied for courses at two Russian universities: Imperial Moscow Technical School (IMTU Russian : ИМТУ ) and

2295-587: Was celebrated as the New Year festival from as early as the 13th century, despite the recorded (civil) year not incrementing until 25 March, but the "year starting 25th March was called the Civil or Legal Year, although the phrase Old Style was more commonly used". To reduce misunderstandings about the date, it was normal even in semi-official documents such as parish registers to place a statutory new-year heading after 24 March (for example "1661") and another heading from

2346-514: Was erected in the estimated location of Pustomazovo in the present-day Ustinovo, north of Kimry in Kimrsky District , Tver Oblast . The local high school in Ustinovo was renamed after Tupolev and a memorial plaque was installed. In 1988, the Soviet Union issued a postage stamp dedicated to Tupolev. The 1979 biographical film Poema o kryl'yakh (Поэма о крыльях) directed by Daniil Khrabrovitsky

2397-528: Was established with support of TsAGI's research and knowledge base to educate specialists for aerospace industry. Among TsAGI's developments are the participation in the rocket Energia and the Space Shuttle Buran projects.

2448-419: Was formally renamed to Vnukovo Andrei Tupolev International Airport. On December 1, 2022, in honor of the 100th anniversary of aircraft designer Andrei Tupolev, his first monument was opened in Moscow . He appeared next to the building of the design bureau on the embankment of Academician Tupolev in the square of the same name. The sculpture is made of bronze and represents the figure of an aircraft designer and

2499-496: Was implemented in Russia on 14 February 1918 by dropping the Julian dates of 1–13 February 1918 , pursuant to a Sovnarkom decree signed 24 January 1918 (Julian) by Vladimir Lenin . The decree required that the Julian date was to be written in parentheses after the Gregorian date, until 1 July 1918. It is common in English-language publications to use the familiar Old Style or New Style terms to discuss events and personalities in other countries, especially with reference to

2550-506: Was partly relocated to the former dacha settlement Otdykh (literally, "Relaxation") converted to the new urban-type settlement Stakhanovo . It was named after Alexey Stakhanov , a famous Soviet miner. On April 23, 1947, the settlement was granted town status and renamed to Zhukovsky . The Moscow branch of the institute is known Moscow complex of TsAGI . In 1965 in Zhukovsky a Department of Aeromechanics and Flight Engineering of MIPT

2601-488: Was to get an aeroplane into service very rapidly, then began an often interminable process of improving the shortcomings of the "quick and dirty" initial design. To his competitors among the Soviet aircraft design community, he was known above all as politically astute; a shrewd and unforgiving rival. Tupolev died on 23 December 1972 and was buried in Novodevichy Cemetery in Moscow. Various streets in cities across
