Sopwith Dragon
The Sopwith Dragon was a British single-seat fighter biplane developed from the Sopwith Snipe. Design and development In April 1918, the sixth Snipe prototype was fitted with a 320 hp (239 kW) ABC Dragonfly I radial engine.Mason 1992, p. 144.Davis 1999, p. 139. To compensate for the greater weight of the Dragonfly, the fuselage was lengthened by 22 in (56 cm).Davis 1999, p. 140. The prototype suffered persistent ignition system defects, but performance was encouraging when the Dragonfly engine operated properly.Davis 1999, p. 140.Robertson 1970, p. 226. In June 1918, the Royal Air Force issued a contract for 30 Dragonfly-engined Snipes, which were subsequently named Dragons.Davis 1999, p. 140.Robertson 1970, p. 226. In late November 1918, the RAF cancelled a production order for 300 Snipes and reordered the aircraft as Dragons.Mason 1992, p. 144. A second prototype was equipped with the larger 360 hp (268 kW) ABC Dragonfly IA engine.Mason 1992, p. 1 ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

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 ...

1910s British Fighter Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

List Of Aircraft Of The Royal Air Force
Many aircraft types have served in the British Royal Air Force since its formation in April 1918 from the merger of the Royal Flying Corps and Royal Naval Air Service. This is a list of RAF aircraft, including all currently active and retired types listed in alphabetic order by their RAF type name. For just those aircraft currently in service, see List of active United Kingdom military aircraft. Aircraft operated with the Fleet Air Arm from 1924 until 1939 were operated by the Royal Air Force on behalf of the Navy and are included; those operated by the Royal Navy after it re-acquired control of the aircraft used to support its operations in 1939 are not, but all aircraft operated in conjunction with the Navy are listed at List of aircraft of the Fleet Air Arm. Army Air Corps aircraft are not included but can be found at List of aircraft of the Army Air Corps. For aircraft operated before the merger of the RFC and RNAS in 1918: * Refer to List of aircraft of the Royal Flying C ...

Sopwith Salamander
The Sopwith TF.2 Salamander was a British ground-attack aircraft of the First World War designed by the Sopwith Aviation Company which first flew in April 1918. It was a single-engined, single-seat biplane, based on the Sopwith Snipe fighter, with an armoured forward fuselage to protect the pilot and fuel system from ground fire during low level operations. It was ordered in large numbers for the Royal Air Force but the war ended before the type could enter squadron service, although two were in France in October 1918. Design and development In August 1917, the British Royal Flying Corps (RFC) introduced the coordinated mass use of single-seat fighter aircraft for low-level ground-attack operations in support of the Third Battle of Ypres, with Airco DH.5s, which were unsuitable for high-altitude combat, specialising in this role. The tactic proved effective and was repeated at the Battle of Cambrai in November 1917 by DH.5s and Sopwith Camels being used in strafing attacks. Whi ...

Vickers Machine-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 ...

ABC Dragonfly
The ABC Dragonfly was a British radial engine developed towards the end of the First World War. It was expected to deliver excellent performance for the time and was ordered in very large numbers. It proved, however, to be extremely unreliable and was abandoned when its faults were unable to be corrected. Design and development ABC Motors was founded in 1911 by Granville Bradshaw, who was also the company's chief designer. In 1917, after initial promising tests of the ABC Wasp air-cooled radial, Bradshaw produced a design for a larger and more powerful engine, the nine-cylinder Dragonfly. The engine was simple and easy to produce, and was predicted to give 340 hp (254 kW) for a weight of 600 lb (273 kg). One distinctive feature was the use of copper-plated cooling fins, which were claimed by Bradshaw to be so effective that water would not boil on the surface of the radiators.Bruce 1974, p.292 On the basis of the promised performance, Sir William Weir, the ...

Sopwith Snipe
The Sopwith 7F.1 Snipe was a British single-seat biplane fighter of the Royal Air Force (RAF). It was designed and built by the Sopwith Aviation Company during the First World War, and came into squadron service a few weeks before the end of the conflict, in late 1918. The Snipe was not a fast aircraft by the standards of its time, but its excellent climb and manoeuvrability made it a good match for contemporary German fighters. It was selected as the standard postwar single-seat RAF fighter and the last examples were not retired until 1926. Design and development In April 1917, Herbert Smith, the chief designer of the Sopwith Company, began to design a fighter intended to be the replacement for Sopwith's most famous aeroplane, the Sopwith Camel.Lumsden ''Aeroplane Monthly'' October 1990, p. 588. The design, called Snipe by Sopwith, was in its initial form a single- bay biplane, slightly smaller than the Camel and intended to be powered by similar engines. The pilot sat higher ...
