Vickers Venom
The Vickers Type 279 Venom was a British low-wing monoplane single-seat, single-engined, eight-gun fighter aircraft. It was fast and manoeuvrable but its Bristol Aquila radial engine was underpowered. Together with other designs built to the same specification, which included the Bristol Type 146, Gloster F.5/34, and Martin-Baker MB 2, it was rejected by the Air Ministry and only one Venom was built. Design and development The Vickers Venom Andrews and Morgan 1988, pp. 246–50, 254. was designed to meet Air Ministry specification F.5/34 which called for a single-seat eight-gun aircraft with the high maximum speed and rate of climb needed to catch bombers flying at . Submissions were expected to use a radial engine for good performance in the tropics Bowyer , 1984, p.34 Vickers based their entrant on their earlier Type 151 Jockey fighter, using the same wing and tail airfoil sections and dimensions but replacing the Wibault-Vickers ribbed construction of the Jockey with a more ...

Sleeve Valve
The sleeve valve is a type of valve mechanism for piston engines, distinct from the usual poppet valve. Sleeve valve engines saw use in a number of pre-World War II luxury cars and in the United States in the Willys-Knight car and light truck. They subsequently fell from use due to advances in poppet-valve technology, including sodium cooling, and the Knight system double sleeve engine's tendency to burn a lot of lubricating oil or to seize due to lack of it. The Scottish Argyll company used its own, much simpler and more efficient, single sleeve system (Burt-McCollum) in its cars, a system which, after extensive development, saw substantial use in British aircraft engines of the 1940s, such as the Napier Sabre, Bristol Hercules, Centaurus, and the promising but never mass-produced Rolls-Royce Crecy, only to be supplanted by the jet engines. Description A sleeve valve takes the form of one or more machined sleeves. It fits between the piston and the cylinder wall in the cylin ...

Curtiss P-36 Hawk
The Curtiss P-36 Hawk, also known as the Curtiss Hawk Model 75, is an American-designed and built fighter aircraft of the 1930s and 40s. A contemporary of the Hawker Hurricane and Messerschmitt Bf 109, it was one of the first of a new generation of combat aircraft—a sleek monoplane design with a retractable undercarriage making extensive use of metal in its construction. Perhaps best known as the predecessor of the Curtiss P-40 Warhawk, the P-36 saw little combat with the United States Army Air Forces during World War II. It was the fighter used most extensively and successfully by the French Air Force during the Battle of France. The P-36 was also ordered by the governments of the Netherlands and Norway but did not arrive in time to see action before both were occupied by Nazi Germany. The type was also manufactured under license in China, for the Republic of China Air Force, as well as in British India, for the Royal Air Force (RAF) and Royal Indian Air Force (RIAF). Axis pow ...

Boeing P-29
The Boeing P-29 and XF7B-1 were an attempt to produce a more advanced version of the highly successful P-26. Although slight gains were made in performance, the U.S. Army Air Corps and U.S. Navy did not order the aircraft. Design and development The Boeing YP-29 originated as the Model 264, developed as a private venture under a bailment contract negotiated with the U.S. Army. Development of three prototypes was initiated in the interval between the testing of the XP-936 (P-26 prototype, company Model 248) and the delivery of the first P-26A (Model 266) to the U.S. Army. The Model 264 was an updated and modernized P-26, differing in having fully cantilever wings of elliptical-design, wing flaps, enclosed "greenhouse" canopy, and retractable undercarriage. The landing gear was similar to the Boeing Monomail, the main wheels retracting backwards about halfway into the wings. The fuselage and the tail were basically the same as those of the P-26. The 264 retained the proven 550&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vickers Vireo
The Vickers Vireo was an experimental low wing all-metal monoplane built to explore both all-metal service aircraft and the use of catapult launched ship board fighters. Only one was built. Development The Vickers-Wibault construction method was based on the patents of Michel Wibault, who began working with Vickers in 1922. It was a way of producing an all-metal aircraft with an airframe built up from simple, non-machined metal shapes, covered by very thin corrugated light alloy sheets. On the wings, the corrugations were aligned along the chord and longitudinally on the fuselage. The resulting fuselage was not monocoque but was internally braced and the skin on the wings was not stressed. Panels were riveted to each other and to the underlying structure. Vickers first experience of the method was with the licence built Wibault Scout. The first Vickers design using this construction was the Vireo. The Vireo (named after a Latin word thought to mean Greenfinch) was built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Air Force Roundels
The air forces of the United Kingdom – the Royal Navy's Fleet Air Arm, the Army's Army Air Corps and the Royal Air Force use a roundel, a circular identification mark, painted on aircraft to identify them to other aircraft and ground forces. In one form or another, it has been used on British military aircraft from 1915 to the present. Background When the First World War started in 1914 it was the habit of ground troops to fire on all aircraft, friend or foe, so that the need for some form of identification mark became evident.Robertson 1967, p 89 At first the Union Flag was painted under the wings and on the sides of the fuselage. It soon became obvious that at a distance the St George's Cross of the Union Flag was likely to be confused with the Iron Cross that was already being used to identify German aircraft. After the use of a Union Flag inside a shield was tried it was decided to follow the lead of the French who used a tricolour cockade (a roundel of red and white wit ...

Jeffrey Quill
Jeffrey Kindersley Quill, (1 February 1913 – 20 February 1996) was a British test pilot who served on secondment with the Royal Air Force and Royal Naval Volunteer Reserve during the Second World War. He was also the second man to fly the Supermarine Spitfire after Vickers Aviation's chief test pilot, Joseph "Mutt" Summers. After succeeding Summers as Vickers' chief test pilot, Quill test-flew every mark of Spitfire. Quill's work on the aircraft aided its development from a promising but untried prototype to become, with the Hawker Hurricane, an instrument of the Royal Air Force's victory in the Battle of Britain. The Spitfire later played a leading role in gaining Allied air superiority over Europe. Quill later wrote two books about the Spitfire. Early years Quill was born at Littlehampton, Sussex, the youngest of the five children of Arthur Maxwell Quill and Emily Molesworth Kindersley. He was educated at Lancing College, which overlooked Shoreham aerodrome, at that tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Merlin
The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litres (1,650 cu in) capacity. Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called ''Merlin'' following the company convention of naming its four-stroke piston aero engines after birds of prey. After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane and Supermarine Spitfire. The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined Avro Lancaster heavy bomber. A series of rapidly-applied developments, brought about by wartime needs, markedly improved the engine's performance and durability. Starting at 1,000 hp for the first production models, most late war versions produced just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
