De Havilland DH.77
The de Havilland DH.77 was a prototype British fighter aircraft of the late 1920s. Intended as a fast climbing interceptor for Britain's Royal Air Force, the DH.77 was a lightweight low-wing monoplane powered by a relatively low power engine. Despite excellent performance, only one aircraft was built, the Hawker Fury biplane being preferred. Development and design In 1927, the British Air Ministry, faced with the need to deal with increased bomber performance, issued Specification F.20/27 for a single-seat interceptor.Lewis 1979, p.195. Unlike previous fighter Specifications, the resulting aircraft were intended to be short-range (not intended to mount standing patrols), fast climbing high altitude aircraft, carrying a minimum of equipment.Jackson 1987, p.289. To meet this requirement, de Havilland developed as a private ventureLewis 1979, p.197. the DH.77, designed by W.G.

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...

Vickers Jockey
The Vickers Type 151 Jockey was an experimental low-wing monoplane interceptor fighter powered by a radial engine. It was later modified into the Type 171 Jockey II, which had a more powerful engine and detail improvements. Only one was built; it was lost before its development was complete, but the knowledge gained enabled Vickers to produce the more refined Venom. Development In the late 1920s the idea of the interceptor fighter was forming. To deal with the faster and higher flying bombers, fighters had both to be fast at height and quick to get there. The Air Ministry was keen to determine the best aircraft configuration and sought, under Air Ministry specification F.20/27, manufacturers to build biplanes and both low- and high-wing monoplanes. Vickers were asked for a prototype low-wing fighter and this became (somewhat unofficially) called the "Jockey", or sometimes the Jockey I. The name covered Vickers Types 151 and 171; the Jockey II was an early name for the later Vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handley Page Type S
The Handley Page Type S, or HPS-1 was a prototype British carrier-based fighter developed for the United States Navy in the early 1920s. A low-wing monoplane, it was unsuccessful, only two being built and flown. Development and design In 1921 the United States Navy drew up a specification for a single-seat fighter aircraft capable of operating either as a landplane from its aircraft carriers or from the water as a seaplane, seeking designs from both American and European companies. The British aircraft manufacturer Handley Page, which had recently developed the leading edge slot, realised use of slots and flaps could allow a high-speed monoplane to fly at the low speeds needed for carrier operations with a much higher wing loading than a normal biplane, and decided to develop an aircraft to meet this requirement. The resulting design, given the Handley Page designation Type S (and later retrospectively known as the H.P.21) was a small, low-wing cantilever monoplane, with full-sp ...

303 British
The .303 British (designated as the 303 British by the C.I.P. and SAAMI) or 7.7×56mmR, is a calibre rimmed rifle cartridge. The .303 inch bore diameter is measured between rifling lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth military cartridge for rifles and machine guns from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO. Cartridge specifications The .303 British has 3.64 ml (56 grains H2O) cartridge case capacity. The pronounced tapering exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns a ...

H Engine
An H engine is a piston engine comprising two separate flat engines (complete with separate crankshafts), most often geared to a common output shaft. The name "H engine" is due to the engine blocks resembling a letter "H" when viewed from the front. The most successful "H" engine in this form was the Napier Dagger and its derivatives. The name was also applied to engines of the same basic layout, but rotated through 90 degrees—most famously the Napier Sabre series. A variation on the "H" theme were the Fairey Prince (H-16) & Fairey P.24 Monarch, where the two engines retained separate drives, driving Contra-rotating propellers through separate concentric shafts. Although successful, they only existed in prototype form. The H engine is a relatively rare layout, with its main use being in aircraft engines during the 1930s and 1940s. The 1966 Lotus 43 Formula One car used a BRM 16-cylinder H engine, and an 8-cylinder H engine was used for powerboat racing in the 1970s. Design ...

Aeroplane And Armament Experimental Establishment
The Aeroplane and Armament Experimental Establishment (A&AEE) was a research facility for British military aviation from 1918 to 1992. Established at Martlesham Heath, Suffolk, the unit moved in 1939 to Boscombe Down, Wiltshire, where its work continues following privatisation as part of the Qinetiq company. History In 1917, the Experimental Aircraft Flight of the Central Flying School was transferred from Upavon, Wiltshire to a site on the heathland at Martlesham, Suffolk, and on 16 January 1917 Martlesham Heath Airfield was officially opened, as an experimental airfield. The unit was renamed the Aeroplane Experimental Unit, Royal Flying Corps. After the end of World War I the site continued to be used and was, once again, renamed as the Aeroplane and Armament Experimental Establishment of the Royal Air Force. At the outbreak of the Second World War, on 9 September, the A&AEE was removed to RAF Boscombe Down, Wiltshire, owing to the proximity of Martlesham Heath to the ...

RAF Martlesham Heath
Royal Air Force Martlesham Heath or more simply RAF Martlesham Heath is a former Royal Air Force station located southwest of Woodbridge, Suffolk, England. It was active between 1917 and 1963, and played an important role in the development of Airborne Interception radar. History RFC/RAF prewar use Martlesham Heath was first used as a Royal Flying Corps airfield during the First World War. In 1917 it became home to the Aeroplane Experimental Unit, RFC which moved from Upavon with the site named as the Aeroplane Experimental Station which became the Aeroplane Experimental Establishment (Home) in 1920 which became the Aeroplane and Armament Experimental Establishment (A&AEE) in 1924. The A&AEE carried the evaluation and testing of many of the aircraft types and much of the armament and other equipment that would later be used during the Second World War. No. 22 Squadron RAF and No. 15 Squadron RAF were present during the 1920s. No. 64 arrived in the 1930s. RAF Fighter Command ...

Hawker Hornet
The Hawker Fury is a British biplane fighter aircraft used by the Royal Air Force in the 1930s. It was a fast, agile aircraft, and the first interceptor in RAF service capable of speed higher than 200 mph (321 kmh). It was the fighter counterpart to the Hawker Hart light bomber. Design and development The Hawker Fury was a development of the earlier Hawker F.20/27 prototype fighter, replacing the radial engine of the F.20/27 with the new Rolls-Royce F.XI V-12 engine (later known as the Rolls-Royce Kestrel), which was also used by Hawker's new light bomber, the Hawker Hart. The new fighter prototype, known as the Hawker Hornet, first flew at Brooklands, Surrey, in March 1929.Mason 1992, p.213. The Hornet was a single-engined biplane, with single bay wings, initially powered by a 420 hp (313 kW) Rolls-Royce F.XIC engine enclosed by a smooth, streamlined cowling but was quickly re-engined with a 480 hp (358 kW) Kestrel IS.Goulding 1986, p.37.

Rolls-Royce Kestrel
The Kestrel or type F is a 21 litre (1,300 in³) 700 horsepower (520 kW) class V-12 aircraft engine from Rolls-Royce, their first cast-block engine and the pattern for most of their future piston-engine designs. Used during the interwar period, it provided excellent service on a number of British fighters and bombers of the era, such as the Hawker Fury and Hawker Hart family, and the Handley Page Heyford. The engine also sold to international air forces, and it was even used to power prototypes of German military aircraft types that were later used during the Battle of Britain. Several Kestrel engines remain airworthy today. Design and development Origin The Kestrel came about as a result of the excellent Curtiss D-12, one of the first truly successful cast-block engines. Earlier designs had used individually machined steel cylinders that were screwed onto a crankcase, whereas the cast-block design used a single block of aluminium that was machined to form cylinders.

Hubert Broad
Captain Hubert Standford Broad, MBE, AFC (1897–1975) was a British First World War aviator and noted test pilot. Early life Born at Aston Lodge, Watford, Hertfordshire on 18 May 1897, the son of Thomas and Amelia Broad (''née'' Coles), his father was a solicitor; he was educated at St. Lawrence College in Ramsgate, Kent. RNAS aviator Broad learned to fly in 1915 at the Hall School of Flying at Hendon. Flying a single-engined Caudron he received Pilot Certificate No. 2,044, after which he joined the Royal Naval Air Service at Eastchurch. After training he was posted to operations with No. 3 Squadron RNAS based at Dunkirk, France flying the Sopwith Pup. Broad was wounded in the neck during one World War I mission escorting bombers and returned to England to become an Instructor whilst he recuperated. For his second operational tour Broad was seconded to No. 46 Squadron of the Royal Flying Corps flying the Sopwith Camel. At the end of the Great War, Broad became an in ...
