Avro 531
The Avro 531 Spider was a British fighter aircraft built by Avro during the First World War. It did not proceed past the prototype stage. Design and development The Spider was a sesquiplane with a largely conventional configuration, but it used Warren truss-type interplane struts, hence the appellation "Spider". In tests, the aircraft demonstrated exceptional performance, handling, and pilot visibility. By the time it flew, the War Office had already selected the Sopwith Snipe for mass production. A second, refined version, the Avro 531A, apparently never was completed, but some of its components seem to have been used to build a derivative design, the Avro 538. This had standard interplane struts and was intended as a racing aircraft. It was never used for this purpose, however, because it was discovered that it had a faulty wing spar, so the Avro firm used it as a hack instead from May 1919 to September 1920.Donald, p. 77.

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".

Aircraft First Flown In 1918
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-ai ...

Avro Aircraft
AVRO, short for Algemene Vereniging Radio Omroep ("General Association of Radio Broadcasting"), was a Dutch public broadcasting association operating within the framework of the Nederlandse Publieke Omroep system. It was the first public broadcaster in the Netherlands. In 2014 AVRO merged with fellow broadcaster TROS to form AVROTROS. History On 8 July 1923, Hilversumsche Draadlooze Omroep was launched by the Nederlandsche Seintoestellen Fabriek (in English: Dutch Transmitter Factory) under supervision of Willem Vogt. On 21 July 1923, it provided the very first regular radio broadcast in the Netherlands. In 1927 it changed its name into Algemeene Nederlandsche Radio Omroep (ANRO), followed soon by a merger with Nederlandsche Omroep Vereeniging (NOV). On 28 December 1927, the two merged broadcasters continued as Algemeene Vereeniging Radio Omroep (A.V.R.O., in English: "General Association of Radio Broadcasting"). In 1938, AVRO sponsored what was the strongest chess tournamen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Events By place Parthia * King Vologases IV of Parthia dies after a 44-year reign, and is succeeded by his son Vologases V. China * A coalition of Chinese warlords from the east of Hangu Pass launches a punitive campaign against the warlord Dong Zhuo, who seized control of the central government in 189, and held the figurehead Emperor Xian hostage. After suffering some defeats against the coalition forces, Dong Zhuo forcefully relocates the imperial capital from Luoyang to Chang'an. Before leaving, Dong Zhuo orders his troops to loot the tombs of the Ha ... [...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 ...

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 ...

Interplane Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more imp ...

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...
