103-644: The Gloster F.9/37 , also known as the Gloster G.39 , was a British twin-engined design from the Gloster Aircraft Company for a cannon-armed heavy fighter to serve with the Royal Air Force , planned before the Second World War . The F.9/37 was rejected in favour of other designs. A development of the F.9/37 as a night fighter , for a new Air Ministry Specifications F.29/40 – known unofficially as
206-486: A World Airspeed Record of 606 mph (975 km/h) with Group Captain H. Wilson at the controls. During early 1946, another F Mk.4 prototype was used to set a world air speed record of 616 mph (991 km/h) true airspeed with Group Captain "Teddy" Donaldson flying the highly modified Meteor, nicknamed "Yellow Peril." The second pilot in the High Speed Flight , Bill Waterton achieved 614 mph. During

The firm quickly acquired the aircraft component construction activities that were previously being carried out by H H Martyn & Co. for the war effort in order to perform subcontracted work from Airco; the provision of additional production capacity had been

The original two-bladed propeller was found to be inefficient at low airspeeds and the aircraft required a long ground run to get airborne, which caused concern at Fighter Command. Accordingly, trials with a de Havilland variable-pitch propeller demonstrated

During the Gloster years, "Zura" as he came to be known, set an international speed record: London-Copenhagen-London, 4–5 April 1950 at Gloster's instruction to sell the aircraft to the Danish Air Force. In 1952, the two-seat, delta winged Gloster Javelin was developed as an all-weather fighter that could fly above 50,000 feet (15,000 m) at almost
618-722: A decision in December 1936 to replace the Merlin I with the improved Merlin II, which resulted in many detail alterations. Merlin I production ended after 180 were built. This engine had been prioritised for the Fairey Battle light bomber and the Hawker Henley , a failed competitor to the Battle briefly adapted as a target tug which shared common elements with the Hurricane design. By the following December,
721-456: A major motivating factor for Airco's involvement in founding the company. H H Martyn were architectural engineers and had produced items such as propellers before moving to whole fuselages for Airco. The firm rented facilities at Sunningend in Cheltenham , Gloucestershire to serve as their works. By the spring of 1918, the company was producing 45 new Bristol Fighter aircraft per week. As
824-646: A number of manufacturers were to repair and overhaul battle-damaged aircraft including Hurricanes. Some of these were later sent to training units or to other air forces. Factories involved included the Austin Aero Company 's Cofton Hackett plant and David Rosenfield Ltd, based at Barton aerodrome near Manchester . The Canadian Car and Foundry of Fort William, Ontario , Canada was a major Hurricane manufacturer, producing them from November 1938 after receiving their initial contract for 40 Hurricanes. The facility's chief engineer, Elsie MacGill , became known as
927-516: A pattern for Canadian Car and Foundry , one for Iran, one for Poland, three for Romania and 12 for Yugoslavia. All the built for export aircraft were taken from the RAF order and so all originally had an RAF serial. Further exports were done in the final four months of 1939 and early 1940. Hurricane production was increased as part of a plan to create a reserve of attrition aircraft as well as re-equip existing squadrons and newly formed ones such as those of
1030-679: A portion of one hangar from the Air Board. Gradually, Gloucester would relocate its operational base to the Brockworth site. Following the Armistice of 11 November 1918 and the end of the First World War , the company suffered financial losses from the collapse of Airco, only receiving partial compensation for the cancellation of outstanding production orders. In 1920, following the closure of rival British aircraft manufacturer Nieuport & General ,
1133-601: A prototype to be ordered. Camm's response to this rejection was to further develop the design, introducing a retractable undercarriage and replacing the unsatisfactory Goshawk engine with a new Rolls-Royce design, initially designated the PV-12 , which went on to become famous as the Merlin . In August 1934, a one-tenth scale model of the design was produced and sent to the National Physical Laboratory at Teddington , where

#17330848806641236-664: A prototype to the September proposal was placed on 21 February 1935. At the time the armament was two Vickers Mark V machine guns in the fuselage and one Browning machine gun in each wing. Work on stressed skin outer wings to replace the fabric covered ones began in July and the contract was altered in August to include another set of wings with eight guns in them; the guns were to be either Vickers or Brownings. These wings were delivered in June 1936. By
1339-471: A reduction in the Hurricane's take-off run from 1,230 to 750 ft (370 to 230 m). Deliveries of these began in April 1939: this was later replaced by the hydraulically operated constant-speed Rotol propeller, which came into service in time for the Battle of Britain. Then, with tail trimmer set, throttle and mixture lever fully forward... and puffs of grey exhaust smoke soon clearing at maximum r.p.m. came
1442-797: A series of wind tunnel tests confirmed the aerodynamics were satisfactory, and in September 1934 Camm again approached the Air Ministry. This time, the Ministry's response was favourable, and a prototype of the "Interceptor Monoplane" was promptly ordered. In July 1934, at a meeting chaired by Air Commodore Arthur Tedder (director of training), the Air Ministry Science Officer Captain F.W. "Gunner" Hill presented his calculation showing that future fighters must carry no fewer than eight machine guns, each capable of firing 1,000 rounds per minute. / Hill's assistant in making his calculations
1545-568: A specialist night fighter , with nose- and turret-mounted guns, led to Gloster submitting a design based on the F.9/37, fitted with Rolls-Royce Merlin engines, a dorsal four-gun turret and Airborne Interception (AI) radar . This received support from the Air Staff who saw it as superior to the Bristol Beaufighter and the Air Ministry ordered one of the F.9/37 prototypes to be converted to
1648-459: A stalling speed of 57 mph (92 km/h) (only marginally higher than the Gladiator biplane), the last achieved using its flaps . In the course of further testing, it was found that the Hurricane had poor spin recovery characteristics, in which all rudder authority could be lost due to shielding of the rudder. Hawker's response to the issue was to request that spinning tests be waived, but
1751-661: A twin engine jet design. Once the E.28/39 had flown, the Air Staff told Gloster to stop work on their F.18/40 nightfighter (other aircraft could be adapted to replace it) to concentrate on the jet fighter. The jet design became the Gloster Meteor, the only jet to be used in combat by the Allied Forces during the Second World War. First flying with the RAF in 1943, the Meteor commenced operations in mid-1944, only some weeks later than
1854-413: A wooden mock-up had been finished, and although a number of suggestions for detail changes were made, construction of the prototype was approved, and a new specification (F.36/34) was written around the design. In July 1935, this specification was amended to include installation of eight guns. The mock-up conference with Air Ministry staff was on 10 January 1935 at Kingston. The ministry order to purchase
1957-602: The Auxiliary Air Force . Expansion scheme E included a target of 500 fighters of all types by the start of 1938. By the time of the Munich Crisis , there were only two fully operational RAF squadrons of the planned 12 to be equipped with Hurricanes. By the time of the German invasion of Poland there were 16 operational Hurricane squadrons as well as a further two more that were in the process of converting. On 24 August 1939,
2060-613: The Belgian Air Force , and it was intended to arm these aircraft with four 13.2 mm (0.52 in) Browning machine guns . Three were built and two flown with this armament by the time of the German invasion of Belgium in May 1940, with at least 12 more constructed by Avions Fairey armed with the conventional eight rifle calibre machine gun armament. The Hawker Hurricane is a low-wing cantilever monoplane with retractable undercarriage and an enclosed cockpit. The primary structure of

In 1917, during the midst of the First World War, the Gloster Aircraft Company Limited was formed under the name The Gloucestershire Aircraft Company Limited. At the time of its creation, its owners were Hugh Burroughes (1884–1985) and H H Martyn & Co. Limited, who held

#17330848806642266-481: The Gloster Reaper – was dropped so that Gloster could concentrate on existing work and on the nascent British jet projects. Gloster had designed a twin-engined turret-fighter for specification F.34/35 but the single-engined Boulton Paul Defiant for F.9/35 was seen to cover both requirements and the F.34/35 design dropped. Less than two years later, F.9/37 for a "twin-engined single-seat fighter with fixed armament"

To this end, the cockpit was mounted reasonably high in the fuselage, creating a distinctive "hump-backed" silhouette. Pilot access to the cockpit was aided by a retractable " stirrup " mounted below the trailing edge of the port wing. This
2472-528: The Luftwaffe actually lost only one Bf 109. On 13 May 1940, a further 32 Hurricanes arrived. All 10 requested Hurricane squadrons were then operating from French soil and felt the full force of the Nazi offensive. The following day, Hurricanes suffered heavy losses: 27 being shot down, 22 by Messerschmitts, with 15 pilots killed (another died some days later), including Squadron Leader J. B. Parnall (504 Squadron), and
2575-515: The Meuse , at Maastricht . The escort consisted of eight Hurricanes of 1 Squadron, with Squadron Leader P. J. H. "Bull" Halahan in the lead. When the formation approached Maastricht, it was bounced by 16 Bf 109Es from 2./JG 27 . Two Battles and two Hurricanes (including Halahan's) were shot down, two more Battles were brought down by flak and the fifth bomber had to crash-land. The 1 Squadron pilots claimed four Messerschmitts and two Heinkel He 112s , while
2678-529: The Rolls-Royce Goshawk engine. The original 1934 armament specifications for what evolved into the Hurricane were for a similar armament fitment to the Gloster Gladiator : four machine guns; two in the wings and two in the fuselage, synchronised to fire through the propeller arc. By January 1934, the proposal's detail drawings had been finished, but these failed to impress the Air Ministry enough for
2781-615: The Supermarine Spitfire during the Battle of Britain in 1940, but the Hurricane inflicted 60% of the losses sustained by the Luftwaffe in the campaign, and fought in all the major theatres of the Second World War. The Hurricane originated from discussions between RAF officials and aircraft designer Sir Sydney Camm about a proposed monoplane derivative of the Hawker Fury biplane in
2884-567: The "Queen of the Hurricanes". The initiative was commercially driven, but was endorsed by the British government. Hawker recognised that a major conflict was inevitable after the Munich Crisis of 1938 and drew up preliminary plans to expand Hurricane production at a new factory in Canada. Under this plan, samples, pattern aircraft, and design documents stored on microfilm were shipped to Canada. In 1938/39

In response to a request from the French government for the provision of 10 fighter squadrons to provide air support, Air Chief Marshal Sir Hugh Dowding , Commander-in-Chief of RAF Fighter Command, insisted that this number would deplete British defences severely, and so initially only four squadrons of Hurricanes, 1 , 73 , 85 and 87 , were relocated to France, keeping Spitfires back for "Home" defence. The first to arrive
3090-658: The Advanced Air Striking Force (No. 1 to Berry-au-Bac , north-west of Paris; No. 73 to Rouvres ) while two more, No. 85 and No. 87, formed 60 Wing of the Air Component, BEF. While the two squadrons of No. 60 Wing had their Hurricanes painted in the standard colour scheme and markings of Home-based fighters, those of No. 67 Wing differed considerably. It was probably because No. 1 and No. 73 Squadrons were operating in close proximity to French fighter squadrons that these units painted red, white, and blue stripes over

Its manufacture and maintenance were eased by using conventional construction methods so that squadrons could perform many major repairs without external support. The plane was rapidly procured prior to the outbreak of the Second World War; in September 1939, the RAF had 18 Hurricane-equipped squadrons in service. It was relied upon to defend against German aircraft operated by
Gloster F.9/37 - Misplaced Pages Continue
3296-432: The Air Ministry followed. As no existing aircraft was suitable for adaptation to take the new jet engine, and Gloster did not have much workload in its design department, Gloster received a contract in early 1940 – to design and build Britain's first jet aircraft. Two airframes were built in secrecy. Due to the risk of bombing, one of the aircraft was built offsite from Brockworth at Regent Motors Cheltenham. On 15 May 1941,
3399-445: The Air Ministry placed its first order for 600 aircraft. On 26 June 1936 the Air Ministry approved the type name of "Hurricane" that had been proposed by Hawker, and an informal naming ceremony occurred the following month during an official visit by King Edward VIII to Martlesham Heath. It was significantly cheaper to produce than the Supermarine Spitfire and took 10,300 person hours per airframe to produce, compared to 15,200 for
3502-474: The Air Ministry refused the request; the situation was resolved by the Royal Aircraft Establishment (RAE), who established that the aerodynamic problem had been caused by a breakdown of the airflow over the lower fuselage, and could be cured by the addition of a small ventral fairing and extension of the bottom of the rudder. This discovery had come too late for the changes to be incorporated in
3605-649: The British aircraft industry, that would lead to the demise of Gloster. One blind alley was the work done (along with eight other British companies) on designing an aircraft to the same exacting Ministry specification that spawned the BAC TSR-2 . The contract was issued to BAC but the Wilson Government cancelled the TSR2 project. In 1961, the company was merged with Armstrong Whitworth Aircraft Limited to form Whitworth Gloster Aircraft Limited. Following another re-organisation,
3708-476: The British government gave Hawker the clearance to sell excess aircraft to nations that were likely to oppose German expansion. As a result, there were some modest export sales made to other countries; at the earliest opportunity, a former RAF Hurricane I was dispatched to Yugoslavia for evaluation purposes. Shortly after this evaluation, an order for 24 Hurricane Mk.Is for the Royal Yugoslav Air Force
3811-505: The British government gave orders partially to mobilise and No. 1 Group RAF ( Air Vice-Marshal Patrick Playfair ) sent its 10 Fairey Battle day-bomber squadrons to France, according to plans established by the British and French earlier in the year. The group was the first echelon of the RAF Advanced Air Striking Force (AASF) and flew from bases at Abingdon, Harwell, Benson, Boscombe Down and Bicester. The group HQ became

In 1984 Gloster Saro acquired the fire tender business of the Chubb group with the company merging in 1987 with Simon Engineering to form Simon Gloster Saro. The company eventually was used to manufacture both alloy and, later, fibreglass fuel tankers for Companies such as Shell/BP. The site at Brockworth was sold in 1964. In recent years
4223-545: The Gloster name disappeared in 1963. Gloster designed and built several fighters that equipped the British Royal Air Force (RAF) during the interwar years including the Gladiator , the RAF's last biplane fighter. The company built most of the wartime production of Hawker Hurricanes and Hawker Typhoons for their parent company Hawker Siddeley while its design office was working on the first British jet aircraft ,

4326-533: The Hurricane remained in use in theatres of operations where reliability, easy handling and a stable gun platform were more important than performance, typically in roles like ground attack. One of the design requirements of the original specification was that both the Hurricane and the Spitfire were also to be used as night fighters . The Hurricane proved to be a relatively simple aircraft to fly at night, and shot down several German aircraft on night raids. From early 1941
4429-456: The Hurricane was also used as an "intruder" aircraft, patrolling German airfields in France at night to catch bombers taking off or landing. By the middle of 1938, the first 50 Hurricanes had reached squadrons and, at that time, it had been assessed that the rate of production was slightly greater than the RAF's capacity to introduce the new aircraft, which had already been accelerated. Accordingly,
4532-452: The Hurricane's cantilever wing consisted of two steel spars, which possessed considerable strength and stiffness. The wing was described by Flight as relatively straightforward to manufacture, employing simple vertical jigs to attach the two spars, after which the wing ribs were installed using horizontal bolts, forming separate units between the front and rear spars. Hydraulically -actuated split trailing edge flaps were fitted to
4635-428: The Hurricane. A fabric-covered wing was initially adopted in order to accelerate production, while a higher-performing stressed-skin metal wing was introduced in late 1939. The first production Hurricane I first flew on 12 October 1937, flown by Flight Lieutenant Philip Lucas and powered by a Merlin II engine. While a contract for 600 Hurricanes was received on 2 June 1936, deliveries lagged by roughly six months due to
4738-625: The Luftwaffe, including dogfighting with Messerschmitt Bf 109s in multiple theatres of action. The Hurricane was developed through several versions: bomber-interceptors, fighter-bombers , and ground support aircraft as well as fighters. Versions designed for the Royal Navy known as the Sea Hurricane had modifications including an arrestor hook near the tail, enabling operation from ships. Some were converted as catapult-launched convoy escorts. By

The Heinkels, which were flying at sea level in an attempt to avoid fighter attacks, had already been attacked and damaged by two Spitfires from 72 Squadron when six Hurricanes intercepted them. The Hurricanes shot down four of the enemy in rapid succession, 46 Squadron claiming five and the Spitfire pilots two. After his first flight in October 1939, Hurricane pilot Roland Beamont subsequently flew operationally with 87 Squadron, claiming three enemy aircraft during
4944-510: The RAF on behalf of its parent company. During 1939, the company constructed 1,000 Hawker Hurricanes within the first 12 months of the conflict; Gloster delivered the last of its 2,750 Hurricanes in 1942. After ending production of the Hurricane, it was decided to manufacture the newer Hawker Typhoon in its place. Gloster proceeded to construct 3,300 in total, almost the entirety of the type. Frank Whittle had first met Gloster's designer and test pilots in April 1939 and an official approach from
5047-723: The RCAF ordered 24 Hurricanes to equip one fighter squadron, 20 of which were delivered, and two were supplied to Canadian Car and Foundry as pattern aircraft but one probably did not arrive, while the other was returned to Britain in 1940. The first Hurricane built at Canadian Car and Foundry was completed in February 1940. Canadian-built Hurricanes shipped to Britain participated in the Battle of Britain . Overall, some 14,487 Hurricanes and Sea Hurricanes were produced in England and Canada. The majority of Hurricanes, 9,986 were built by Hawker (who produced

In contrast, the contemporary Spitfire used all-metal monocoque construction and was thus both lighter and stronger, though less tolerant of bullet damage. With its ease of maintenance, widely set landing gear and benign flying characteristics,

As war was looking likely, and time was of the essence in providing the RAF with an effective fighter, the authorities expected there to be problems with the more advanced Spitfire, while the Hurricane made use of well proven manufacturing techniques. The service squadrons were also already experienced in maintaining aircraft structurally similar to
SECTION 50
#17330848806645356-420: The acceptance of the final multi-gun wing armament. By March 1936, the prototype had completed ten flying hours, covering all major portions of the flight envelope. Early testing had gone reasonably well, especially in light of the trial status of the Merlin engine, which had yet to achieve full flight certification at this time and thus severe restrictions had been imposed upon use of the engine. In early 1936,
5459-535: The best recorded by a British fighter at the time. Test flights revealed that the prototype was very manoeuvrable and "a delight to fly". After being badly damaged in a landing accident in July 1939, it was re-engined with 900 hp Taurus T-S(a)-IIIs in 1940, which reduced its performance. A second prototype ( L8002 ) with 880 hp Rolls-Royce Peregrine I liquid-cooled, inline engines flew on 22 February 1940; it proved capable of 330 mph (530 km/h) at 15,000 ft (4,600 m).

The Dornier went away unscathed, while Orton was hit by defensive fire and had to force land. On the same day the Hurricane squadrons claimed 42 German aircraft, none of them fighters, shot down during 208 sorties; seven Hurricanes were lost but no pilots were killed. On 12 May several Hurricanes units were committed to escort bombers. That morning, five Fairey Battle volunteer crews from 12 Squadron took off from Amifontaine base to bomb Vroenhoven and Veldwezelt bridges on

With the move to metal construction, the Sunningend factory was soon deemed to be no longer suitable; accordingly, in 1928, Gloster purchased the aerodrome at Brockworth, including all of the adjacent hangars and neighbouring office accommodation. In 1934, Gloster was acquired by another British aircraft manufacturer, Hawker Aircraft . Regardless of this change in ownership,
5871-597: The company continued to produce aircraft under its own brand name. In that same year, Gloster produced one of its most famous aircraft, the Gladiator biplane. The 1935 merger of Hawker Aircraft and the interests of J. D. Siddeley ( Armstrong Siddeley and Armstrong Whitworth Aircraft ) saw Gloster become a part of Hawker Siddeley Aircraft, Ltd. At the outbreak of the Second World War, the firm lacked any modern designs of its own in production, but had significant expertise and production facilities available. Thus, Gloster undertook manufacture for Hawker-designed aircraft to equip
5974-423: The course of RAF trials, despite the problems with the Merlin engine, which had suffered numerous failures and necessitating several changes, enthusiastic reports were produced on the aircraft and its performance. The trials had proved the aircraft to possess a maximum level speed of 315 mph (507 km/h) at an altitude of 16,200 ft (4,900 m), climb to 15,000 ft (4,600 m) in 5.7 minutes, and
6077-513: The earlier fighter specification F.7/30 was a development of the Fury, the Hawker P.V.3 , However, the P.V.3 was not among the proposals which the Air Ministry selected to be built as prototype to official contract. After the rejection of the P.V.3 proposal, Camm started work on a new design involving a cantilever monoplane arrangement with a fixed undercarriage, armed with four machine guns and powered by
6180-520: The early 1930s. Despite an institutional preference for biplanes and lack of interest by the Air Ministry , Hawker refined its monoplane proposal, incorporating several innovations which became critical to wartime fighter aircraft, including retractable landing gear and the more powerful Rolls-Royce Merlin engine. The Air Ministry ordered Hawker's Interceptor Monoplane in late 1934, and the prototype Hurricane K5083 performed its maiden flight on 6 November 1935. The Hurricane went into production for
6283-405: The end of August 1935, work on the airframe had been completed at Hawker's Kingston upon Thames facility and the aircraft components were transported to Brooklands , Surrey , where Hawker had an assembly shed; the prototype was fully re-assembled on 23 October 1935. Ground testing and taxi trials took place over the following two weeks. On 6 November 1935 the prototype K5083 took to the air for

During the early 1930s, when Hawker Aircraft company developed the Hurricane, RAF Fighter Command had just 13 squadrons, equipped with the Hawker Fury , Hawker Demon , or the Bristol Bulldog , all biplanes with fixed- pitch wooden propellers and non-retractable undercarriages. At

Camm had decided to use traditional Hawker construction techniques instead of more advanced options, such as a stressed-skin metal construction. This form of construction resembled that of earlier biplanes and was already considered to be somewhat outdated when the Hurricane was introduced to service . The Hurricane was initially armed with an arrangement of eight remotely-operated wing-mounted Browning machine guns, intended for conducting rapid engagements. The Hurricane

As the French squadrons were not familiar with the British use of code letters, and there could have been cause for error in aircraft identification, both Hurricane squadrons removed their squadron identification letters, leaving the grey-painted aircraft letter aft of the fuselage roundel. The decision to adopt these special changes in markings seems to have been made at 67 Group HQ (the immediate command authority for

Several fabric-wing Hurricanes were still in service during the Battle of Britain, although a good number had had their wings replaced during servicing or after repair. Changing the wings required only three hours work per aircraft. The Hurricane had a inward-retracting undercarriage ,
6901-568: The firm became part of the Avro Whitworth Division of Hawker Siddeley Aviation in 1963, and the name Gloster disappeared as Hawker Siddeley rebranded its product line under its own name. In the late 1960s/early 1970s the Saunders-Roe Folly Works, by then owned by Hawker Siddeley was merged with the Gloster works to form Gloster-Saro utilising both companies' expertise in aluminium forming to produce fire appliances and tankers in

Upon the outbreak of the Second World War, over 550 Hurricanes had been produced equipping 18 squadrons, with 3,500 more on order. During 1940, Lord Beaverbrook , the Minister of Aircraft Production , established the Civilian Repair Organisation through which

Although the E.28.39 could in theory be used as a fighter, a specific fighter design was required and Gloster began work on

In early 1936, the Hawker board of directors had decided, in the absence of official authorisation and at company expense, to proceed with the issue of the design drawings to the production design office and to start tooling-up for a production line capable of producing a batch of 1,000 Hurricanes. In June 1936
7313-402: The first time at the hands of Hawker's chief test pilot , Flight Lieutenant George Bulman . Bulman was assisted by two other pilots in subsequent flight testing; Philip Lucas flew some of the experimental test flights, while John Hindmarsh conducted the firm's production flight trials. As completed, the prototype had been fitted with ballast to represent the aircraft's armament prior to
7416-410: The fuselage was a Warren truss box-girder with high-tensile steel longerons and duralumin cross-bracing, which were mechanically fastened rather than being welded . Over this, a secondary structure composed of wooden formers and stringers covered with doped linen gave the fuselage a rounded section. The majority of the external surfaces were linen, except for a section between the cockpit and
7519-472: The inner end of the wings. This wing was predominantly fabric-covered, like the fuselage, although some lightweight metal sheets were used on the inner wing and its leading edge . The majority of the flight control surfaces , such as the Frise-type ailerons , also had fabric coverings. An all-metal, stressed-skin wing of duraluminium (a DERD specification similar to AA2024) was introduced in April 1939 and
7622-450: The late summer of 1940". Present at the meeting was Squadron Leader Ralph Sorley of the Air Ministry's Operational Requirements branch, who played an important role in the decision. In November 1934, the Air Ministry issued Specification F.5/34 which called for new fighter aircraft to be armed with a total of eight guns. However, by this time, work had progressed too far to immediately modify the planned four-gun installation. By January 1935,
7725-432: The lead. Mölders and Leutnant Hans von Hahn shot down the Hurricanes of Sergeant R. M. Perry and J. Winn for no loss. In May 1940, Nos. 3, 79 and 504 Squadrons reinforced the earlier units as Germany's Blitzkrieg gathered momentum. On 10 May, the first day of the Battle of France , Flight Lieutenant R. E. Lovett and Flying Officer "Fanny" Orton , of 73 Squadron, were the first RAF pilots to engage enemy aircraft in
7828-432: The main undercarriage units being housed in recesses in the wing. Hinged telescopic Vickers-built legs are attached to the bottom boom of the wing's forward spar, but with a angled pivot to allow the strut to be perpendicular to the thrust line when extended and angle rearwards when retracted to clear the forward spar. A hydraulic jack actuated the undercarriage. Two separate hydraulic systems, one being power-operated and
7931-844: The new specification as F.29/40. Unofficially known as the Gloster Reaper, it inherited the admirable handling characteristics of the F.9/37 and despite being judged superior to other designs, including turreted variants of the Beaufighter and de Havilland Mosquito , the Reaper was terminated in May 1941, for Gloster to concentrate on other work, especially the Gloster E.28/39 jet aircraft.

8034-411: The opening months of the war were characterised by little air activity in general, there were sporadic engagements and aerial skirmishes between the two sides. On 30 October 1939 Hurricanes saw action over France. That day, Pilot Officer P. W. O. "Boy" Mould of 1 Squadron, flying Hurricane L1842, shot down a Dornier Do 17 P from 2(F)/123. The German aircraft, sent to photograph Allied airfields close to
8137-495: The orders for aircraft increased, other companies in the Gloucester and Cheltenham district were contracted with work. Where any flying was involved, the aircraft would be transported (with wings detached) to a newly formed Air Board aircraft acceptance park at Brockworth , seven miles (11 km) away by motor transport. Although Brockworth Aerodrome was used by the company, it lacked any hangars until 1921, after which it would rent
8240-460: The other hand-operated, are present for the deployment and retraction of the undercarriage; in the event of both failing, pilots can release the retaining catches holding the undercarriage in place, deploying the wheels to the 'down' position using weight alone. A wide wheel-track was used to allow for considerable stability during ground movements and to enable tight turns to be performed. The prototype and early production Hurricanes were fitted with
8343-563: The prototype was transferred to RAF Martlesham Heath , Suffolk , to participate in initial service trials under the direction of Squadron Leader D.F. Anderson. Sammy Wroath, later to be the founding commandant of the Empire Test Pilots' School , was the RAF test pilot for the Hurricane: his report was favourable, stating that: "The aircraft is simple and easy to fly and has no apparent vices" and proceeded to praise its control response. In

Meteors remained in service with several air forces for many years and saw action in the Korean War with the Royal Australian Air Force (RAAF). Eventually, Gloster Meteors in fighter, trainer and night fighter versions were in operational use by 12 nations. During Gloster's heyday, in 1947, S/L Janusz Zurakowski
8549-400: The runway and old buildings have been demolished and replaced by standard modern industrial estate and office buildings. Hawker Hurricane The Hawker Hurricane is a British single-seat fighter aircraft of the 1930s–40s which was designed and predominantly built by Hawker Aircraft Ltd. for service with the Royal Air Force (RAF). It was overshadowed in the public consciousness by
8652-688: The services of its former chief designer, Henry Folland (1889–1954), were hired by the company; it also acquired the rights for the Nieuport Nighthawk fighter and various unassembled aircraft components. In December 1926, it was decided that the name of the company should be switched to a simplified form—the Gloster Aircraft Company. This was reported because customers outside of the United Kingdom found it easier to pronounce and to spell. Typically, locals and employees simply referred to
8755-412: The speed of sound. This modern aircraft proved to be too heavy to take off from the short airfield in Brockworth, and was instead fitted out to the bare minimum and given a very small fuel load. It was then flown in a short hop to RAF Moreton Valence seven miles (11.27 km) to the south west, where the aircraft would be completed. It was this shortcoming of facilities, along with the rationalisation of
8858-497: The steel tubes were damaged, the repair work required was relatively simple and could be done by ground crew at the airfield. Damage to a stressed skin structure, as used by the Spitfire, required more specialised equipment to repair. The old-fashioned structure also permitted the assembly of Hurricanes with relatively basic equipment under field conditions. Crated Hurricanes were assembled at Takoradi in West Africa and flown across
8961-413: The surprise! There was no sudden surge of acceleration, but with a thunderous roar from the exhausts just ahead on either side of the windscreen, only a steady increase in speed... In retrospect that first Hurricane sortie was a moment of elation, but also of relief. Apart from the new scale of speeds that the pilot had to adapt to, the Hurricane had all the qualities of its stable, secure biplane predecessor
9064-584: The time, there was an institutional reluctance towards change within the Air Staff ; some senior figures were prejudiced against the adoption of monoplane fighter aircraft, while mid-level officers were typically more open-minded. In 1934 the British Air Ministry issued Specification F.5/34 in response to demands within the Royal Air Force (RAF) for a new generation of fighter aircraft . Earlier, during 1933, British aircraft designer Sydney Camm had conducted discussions with Major John Buchanan of
9167-510: The two squadrons involved) to suit local circumstances. The Hurricane had its first combat action on 21 October 1939, at the start of the Phoney War . That day, "A" Flight of 46 Squadron took off from North Coates satellite airfield, on the Lincolnshire coast, and was directed to intercept a formation of nine Heinkel He 115 B floatplanes from 1/KüFlGr 906, searching for ships to attack in
9270-493: The type at Brooklands from December 1937 to October 1942 and Langley from October 1939 to July 1944), while Hawker's sister company, the Gloster Aircraft Company , constructed 2,750. The Austin Aero Company completed 300 Hurricanes. Canada Car and Foundry produced 1,451 Hurricanes. However those shipped to Britain were often incomplete airframes and about 80% were delivered without an engine. In 1939, production of 100 Hurricanes
9373-494: The wings and two in the nose and powered by the Goshawk engine was prepared and discussed with Roger Liptrot of the Air Ministry in December 1933. The design was reworked with the PV.12, following detailed work working drawings of the "Interceptor Monoplane" were begun in May 1934. The complete design was presented to the Air Ministry on 4 September. Camm's initial submission in response to
9476-592: The world's first operational jet, the German Messerschmitt Me 262 . Crucially, it became the first RAF aircraft with a high enough top speed to enable it to fly alongside V1 flying bombs and tip them under the wing so as to render the V1's gyro incapable of recovery. This made the V1s crash prematurely to earth in open countryside before they could reach London. In 1945, a Meteor F Mk.4 prototype, stripped of armament, achieved
9579-445: Was 73 Squadron on 10 September 1939, followed shortly by the other three. A little later, 607 and 615 Squadrons joined them. Owing to the Hurricane's rugged construction, ease of maintenance and repair in the field, and its docile landing and take-off characteristics, coupled with a wide-track undercarriage, it was selected to go to France as the principal RAF fighter. Two Hurricane squadrons, No. 1 and No. 73 , formed 67 Wing of
9682-549: Was a British aircraft manufacturer from 1917 to 1963. Founded as the Gloucestershire Aircraft Company Limited during the First World War, with the aircraft construction activities of H.H. Martyn & Co. of Cheltenham, England it produced fighters during the war. It was renamed later as foreigners found 'Gloucestershire' difficult to pronounce. It later became part of the Hawker Siddeley group and
9785-495: Was employed as an experimental pilot. In the following years, he became one of the world's most famous experimental and aerobatics pilots. He developed a new aerobatic manoeuvre, the "Zurabatic Cartwheel", which held the audience captivated as he suspended the Gloster Meteor G-7-1 prototype he was flying, in a vertical cartwheel at the 1951 Farnborough Air Show, a manoeuvre the announcer declared to be "Impossible!" Serving for
9888-495: Was his 13-year-old daughter Hazel Hill . Of the decision to place eight machine guns in fighters, Claude Hilton Keith , at the time assistant director of armament research and development, said "The battle was brisk and was carried into very high quarters before the implementing authority was given. My Branch had made out a sound case for 8-gun fighters and if this recommendation had not been accepted and we had been content with half-measures, it might indeed have gone ill for us during
9991-546: Was initiated in Yugoslavia by Zmaj and Rogožarski . Of these, 20 were built by Zmaj by April 1941. Recognising that the supply of British-made Merlin engines might not be guaranteed, it was decided to fit one of the Yugoslavian Hurricanes with a Daimler-Benz DB 601 engine instead. This aircraft was flown in 1941. In 1938, a contract for 80 Hurricanes was placed with Fairey's Belgian subsidiary Avions Fairey SA for
10094-591: Was issued. The F.9/37 was designed under the direction of George Carter , his first for Gloster, to F.9/37 (hence the name) as a single-seat fighter carrying an armament of four 0.303 in (7.7 mm) Browning machine guns and two 20 mm Hispano cannon in the nose. Intended for dispersed production by semi-skilled labour, the structure broke down into sub-assemblies. A prototype ( military serial L7999 ) with 1,060 hp Bristol Taurus T-S(a) radial engines flew on 3 April 1939 and demonstrated excellent performance, its maximum speed of 360 mph (580 km/h) being
10197-406: Was linked to a spring-loaded hinged flap which covered a handhold on the fuselage, just behind the cockpit. When the flap was shut, the footstep retracted into the fuselage. In addition, both wing roots were coated with strips of non-slip material. An advantage of the steel-tube structure was that cannon shells could pass right through the wood and fabric covering without exploding. Even if one of
10300-732: Was received; this was followed by the purchase of a production licence for the Hurricane by Yugoslavia. Yugoslavian Hurricanes saw action against the Luftwaffe during the invasion of Yugoslavia in 1941 by the Axis powers . To the end of August 1939, 14 Hurricanes had been sent to Poland (SS Lassel left Liverpool on 30 August 1939 heading to Constanza in Romania, these planes never reached Poland and ultimately were sold to Turkey ), seven ex-RAF Hurricanes had been sent to South Africa, while another 13 ex-RAF Hurricanes were sent to Turkey, 13 Hurricanes had been built for Belgium, 21 for Canada including one as
10403-719: Was the first to clash with a Messerschmitt Bf 109 . After the dogfight, he came back with five holes in his fuselage. Flying Officer Cobber Kain , a New Zealander, was responsible for 73 Squadron's first victory, on 8 November 1939 while stationed at Rouvres . He went on to become one of the RAF's first fighter aces of the war, being credited with 16 kills. On 22 December, the Hurricanes in France suffered their first losses: three, while trying to intercept an unidentified aircraft between Metz and Thionville , were jumped by four Bf 109Es from III./JG 53, with their Gruppenkommandeur , Spanish Civil War ace Captain Werner Mölders , in
10506-402: Was typically equipped for flying under both day and night conditions, being provided with navigation lights, Harley landing lights , complete blind-flying equipment, and two-way radios . Upon its entry to service, much of the performance data was intentionally concealed from the general public, but it was known that the type possessed a speed range of 6:1. A simple steel tube structure supported
10609-420: Was used for all of the later marks. "The metal skinned wings allowed a diving speed that was 80 mph (130 km/h) higher than the fabric-covered ones. They were very different in construction but were interchangeable with the fabric-covered wings; one trials Hurricane, L1877 , was even flown with a fabric-covered port wing and metal-covered starboard wing. The great advantage of the metal-covered wings over
