Vickers Venture
The Vickers Type 94 Venture was a British army cooperation biplane of the 1920s, designed and built by Vickers, as a development of the Vixen. While six were built for the Royal Air Force, they were found unsuitable and were used for experimental work. Development and design The Venture was a further development of the Vixen II to meet the requirements of Air Ministry Specification 45/23, six aircraft being ordered. The Venture, like the Vixen which formed its basis, was a single-bay biplane with a steel tube fuselage and wooden wings. It used the wings of the Vixen II with the lengthened fuselage of the Vixen III. The first Venture flew at the Vickers factory at Brooklands on 3 June 1924, being sent to the Aeroplane and Armament Experimental Establishment at Martlesham for evaluation. While demonstrating what was said to be "docile" handling, further testing showed that the aircraft had poor longitudinal stability, had a long landing run and was considered too large for use ...

W Engine
A W engine is a type of piston engine where three or four cylinder banks use the same crankshaft, resembling the letter W when viewed from the front. W engines with three banks of cylinders are also called "broad arrow" engines, due to their shape resembling the British government broad arrow property mark. W engines are less common than V engines. Compared with a V engine, a W engine is typically shorter and wider. W3 engines One of the first W engines was the Anzani 3-cylinder, built in 1906, to be used in Anzani motorcycles. It is this W3 engine which also powered the 1909 Blériot XI, the first airplane to fly across the English Channel. The ''Feuling W3'' is a motorcycle engine that was built by an aftermarket parts company in the United States in the early 2000s. Like radial aircraft engines it has a master connecting rod and two slave rods connected to the pistons. W6 engines The Rumpler Tropfenwagen had a Siemens and Halske-built overhead valve W6 engine, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers Aircraft
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems. History Early history Vickers was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law George Naylor in 1 ...

Vickers Valparaiso
The Vickers Valparaiso was a British light bomber biplane of the 1920s. It was designed by Vickers as a development of its Vickers Vixen, Vixen for export, being sold to Portugal and Chile. Development and design The Vickers Valparaiso was a derivative of the Vickers Vixen, Vixen I for export purposes. It was renamed Valparaiso to distinguish it from the Vixen, which as it used Secrecy, classified government equipment, was unavailable for export. Two versions were available, one powered by the same Napier Lion as the Vixen, known as the Type 93 Valparaiso I, while the Type 92 Valparaiso II was powered by the Rolls-Royce Eagle engine Donald 1997, p.892. Other than their engines, the Valparaisos were very similar to the Vixen I, both being single-bay biplanes with wooden wings and steel tube fuselages. Both versions were purchased by Portugal, which ordered ten Valparaiso Is and four Valparaiso IIs, with the Lion-powered aircraft to serve as reconnaissance bombers and the lower po ...

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 Machine Gun
The Vickers machine gun or Vickers gun is a Water cooling, 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 Allies of World War I, 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 Britis ...

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 ...

Napier Lion
The Napier Lion is a 12-cylinder, petrol-fueled 'broad arrow' W12 configuration aircraft engine built by D. Napier & Son from 1917 until the 1930s. A number of advanced features made it the most powerful engine of its day and kept it in production long after other contemporary designs had been superseded. It is particularly well known for its use in a number of racing designs, for aircraft, boats and cars. Design and development Early in the First World War, Napier were contracted to build aero engines to designs from other companies, initially a Royal Aircraft Factory model and then Sunbeams. Both engines proved to be unreliable and in 1916 Napier decided to design an engine with high power, light weight and low frontal area. Napier's engineers laid out the engine with its 12 cylinders in what they called a "broad arrow"—three banks of four cylinders sharing a common crankcase. This suggested the design's first name, the Triple-Four. The configuration is also known as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
