Hawker Harrier
The Hawker Harrier was an experimental biplane torpedo bomber aircraft built by Hawker Aircraft to a specification issued in the 1920s for the RAF. Development In 1925, the British Air Ministry laid down specifications for a high altitude bomber to replace the Hawker Horsley and for a coastal torpedo bomber ( Specifications 23/25 and 24/25). As these specifications were similar, the Air Ministry announced that a single competition would be held to study aircraft submitted for both specifications. Sydney Camm of Hawker Aircraft designed the Harrier to meet the requirements of Specification 23/25, with the prototype (''J8325'') first flying in February 1927, the first of the competitors for the two specifications to fly. The Harrier was a two-seat biplane with single-bay wings powered by a geared Bristol Jupiter VIII radial engine. It was armed with one .303 in (7.7 mm) Vickers machine gun and one .303 in (7.7 mm) Lewis gun carrying a maximum of of bombs. ...

Bristol Aeroplane Company
The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the company. In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley. BAC went on to become a founding component of the nationalised British Aerospace, now BAE Systems. Bristol Siddeley was purchased by Rolls-Royce in 1966, who continued to develop and market Bristol-designed engines. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Aircraft
Hawker Aircraft Limited was a British aircraft manufacturer that was responsible for some of the most famous products in British aviation history. History Hawker had its roots in the aftermath of the First World War, which resulted in the bankruptcy of the Sopwith Aviation Company. Sopwith test pilot Harry Hawker and three others, including Thomas Sopwith, bought the assets of Sopwith and formed H.G. Hawker Engineering in 1920. In 1933, the company was renamed Hawker Aircraft Limited, and it took advantage of the Great Depression and a strong financial position to purchase the Gloster Aircraft Company in 1934. The next year, it merged with the engine and automotive company Armstrong Siddeley and its subsidiary, Armstrong Whitworth Aircraft, to form Hawker Siddeley Aircraft. This group also encompassed A. V. Roe and Company (Avro). The company continued to produce designs under the "Hawker" name as part of Hawker Siddeley Aircraft, which from 1955 was a division of Hawker S ...

Blackburn Beagle
The Blackburn B.T.1 Beagle was a British single-engine, two-seat biplane bomber/torpedo aircraft from 1928. Designed to Air Ministry specifications which led to no contracts for any manufacturer, only one Beagle was built. Development The B.T. in the Beagle's designation stood for bomber and torpedo, the first aircraft that Blackburn had built for both roles. Its design was started to Air Ministry specification 24/25 for a high-altitude bomber, but was later modified to meet specification 23/25 for a day bomber, reconnaissance and torpedo aircraft. The Beagle was a single-bay biplane with staggered and slightly swept wings. The fabric-covered wings, which did not fold as the aircraft was not intended for carrier service, had spruce spars and ribs with metal bracing. Four ailerons were fitted. The fuselage followed standard Blackburn practice with a steel tube centre section and wooden construction aft, though the final section was again of tube steel; covering was fabric thr ...

Scarff Ring
The Scarff ring was a type of machine gun mounting developed during the First World War by Warrant Officer (Gunner) F. W. Scarff of the Admiralty Air Department for use on two-seater aircraft. The mount incorporated bungee cord suspension in elevation to compensate for the weight of the gun, and allowed an airgunner in an open cockpit to swivel and elevate his weapon (a Lewis machine gun) quickly, and easily fire in any direction. Later models permitted the fitting of two Lewis guns; while this doubled the firepower available, operation of the paired guns was more cumbersome, and required considerable strength from the gunner, especially at altitude, so that many gunners preferred the original single gun - and this became the postwar standard. In either case, the mounting was simple and rugged, and gave its operator an excellent field of fire. It was widely adapted and copied for other airforces. As well as becoming a standard fitting in the British forces during the First World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers Gun
The Vickers machine gun or Vickers gun is a water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allied World War I fighter aircraft. The weapon had a reputation for great solidity and reliability. Ian V. Hogg, in ''Weapons & War Machines'', describes an action that took place in August 1916, during which the British 100th Company of the Machine Gun Corps fired their ten Vickers guns to deliver sustained fire for twelve hours. Using 100 barrels, they fired a million rounds without breakdowns. "It was this absolute foolproof reliability which endeared the Vickers to every British soldier who ever fired one. It neve ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Bristol Hydra
The Bristol Hydra (also known as the Double Octagon) was an experimental 16-cylinder, twin-row radial aircraft engine built by the Bristol Engine Company. It is a relatively rare example of a radial with an even number of cylinders per rowit is often claimed that radial engines require an odd number of cylinders, but this is simply easier, not physically required. Only two Hydras were built, the type never entered production. Design and development It appears the Hydra was built as a "backup" design in case the newer sleeve valve engines being designed by Roy Fedden at the same time proved unworkable. Design of the Hydra was led by Frank Owner, who built an experimental V-4 design to test a new twin overhead cam design, a first for Bristol engines which normally used pushrods and rockers. When the V-4 ran successfully, it seems they used four such engines connected to a common crankcase to produce the Hydra. The cams were operated by rotating shafts leading from the crankshaf ...

Vickers Vildebeest
The Vickers Vildebeest and the similar Vickers Vincent were two very large two- to three-seat single-engined British biplanes designed and built by Vickers and used as light bombers, torpedo bombers and in army cooperation roles. First flown in 1928, it remained in service at the start of the Second World War, with the last Vildebeests flying against Japanese forces over Singapore and Java in 1942. Design and development Vildebeest Designed against Air Ministry Specification 24/25 for the Royal Air Force (RAF), for a land-based torpedo bomber to replace the Hawker Horsley, the prototype Vildebeest, an all-metal fuselage aircraft with single-bay unstaggered fabric-covered wings and tail, was first flown in April 1928 as the Vickers Type 132, powered by a Bristol Jupiter VIII radial engine.Mason 1994, p. 200. After initial evaluation, the Vildebeest was shortlisted for comparison with the Blackburn Beagle and Handley Page Hare. As the Jupiter VIII was prone to vibration, a ...
