Koolhoven F.K.58
The Koolhoven F.K.58 was a single engine, interceptor-fighter aircraft designed and mainly manufactured by N V Koolhoven in the Netherlands under contract by France. Intended for ''Armée de l'Air'' use, the F.K.58 saw limited service in the Battle of France. Design and development In 1938, the French Air Ministry noticed that domestic aircraft manufacturing capacity could not re-equip the ''Armée de l'Air'' with modern fighters quickly enough. In order to win some contracts with the French, the Dutch manufacturer Koolhoven quickly designed a single-seat fighter that would use French-supplied engines and other components. The Koolhoven fighter was intended primarily for fighter units based in the colony of French Indochina. The prototype, designed by Erich Schatzki and powered by a Hispano-Suiza 14AA radial engine, flew for the first time on 17 July 1938. The structure of the fuselage consisted of welded steel tubing covered with sheet metal (front part) and fabric (aft); t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

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 ...

Ad Hoc
Ad hoc is a Latin phrase meaning literally 'to this'. In English, it typically signifies a solution for a specific purpose, problem, or task rather than a generalized solution adaptable to collateral instances. (Compare with ''a priori''.) Common examples are ad hoc committees and commissions created at the national or international level for a specific task. In other fields, the term could refer to, for example, a military unit created under special circumstances (see '' task force''), a handcrafted network protocol (e.g., ad hoc network), a temporary banding together of geographically-linked franchise locations (of a given national brand) to issue advertising coupons, or a purpose-specific equation. Ad hoc can also be an adjective describing the temporary, provisional, or improvised methods to deal with a particular problem, the tendency of which has given rise to the noun ''adhocism''. Styling Style guides disagree on whether Latin phrases like ad hoc should be italicized. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Overseas Territories
Overseas France (french: France d'outre-mer) consists of 13 French-administered territories outside Europe, mostly the remains of the French colonial empire that chose to remain a part of the French state under various statuses after decolonization. They are part of the European Union. This collective name is used in everyday life in France but is not an administrative designation in its own right. Instead, the five overseas regions have exactly the same administrative status as the metropolitan regions; the five overseas collectivities are semi-autonomous; and New Caledonia is an autonomous territory. Overseas France includes island territories in the Atlantic, Pacific and Indian Oceans, French Guiana on the South American continent, and several peri-Antarctic islands as well as a claim in Antarctica. Excluding the district of Adélie Land, where French sovereignty is effective ''de jure'' by French law, but where the French exclusive claim on this part of Antarctica is f ...

Airstrike
An airstrike, air strike or air raid is an offensive operation carried out by aircraft. Air strikes are delivered from aircraft such as blimps, balloons, fighters, heavy bombers, ground attack aircraft, attack helicopters and drones. The official definition includes all sorts of targets, including enemy air targets, but in popular usage the term is usually narrowed to a tactical (small-scale) attack on a ground or naval objective as opposed to a larger, more general attack such as carpet bombing. Weapons used in an airstrike can range from direct-fire aircraft-mounted cannons and machine guns, rockets and air-to-surface missiles, to various types of aerial bombs, glide bombs, cruise missiles, ballistic missiles, and even directed-energy weapons such as laser weapons. In close air support, air strikes are usually controlled by trained observers on the ground for coordination with ground troops and intelligence in a manner derived from artillery tactics.

Fokker G
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912.

Bristol Mercury VIII
The Bristol Mercury is a British nine-cylinder, air-cooled, single-row, piston radial engine. Designed by Roy Fedden of the Bristol Aeroplane Company it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Jupiter engine, later variants could produce 800 horsepower (600 kW) from its capacity of 1,500 cubic inches (25 L) by use of a geared supercharger. Almost 21,000 engines were produced, with a number also being built under license elsewhere in Europe. Several examples remain airworthy, with other preserved examples on public display in aviation museums. Design and development The Mercury was developed by the Bristol Aeroplane Company in 1925 as their Bristol Jupiter was reaching the end of its lifespan. Although the Mercury initially failed to attract much interest, the Air Ministry eventually funded three prototypes and it became another winner for the designer Roy Fedden. With the widespread introduction of superchar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Taurus
The Taurus is a British 14-cylinder two-row radial aircraft engine, produced by the Bristol Engine Company starting in 1936. The Taurus was developed by adding cylinders to the existing single-row Aquila design and transforming it into a twin-row radial engine, creating a powerplant that produced just over 1,000 horsepower (750 kW) with very low weight. Design and development Bristol had originally intended to use the Aquila and Perseus as two of its major product lines in the 1930s, but the rapid increase in size and speed of aircraft in the 1930s demanded much larger engines than either of these. The mechanicals from both of these designs were then put into two-row configurations to develop much larger engines, the Aquila becoming the Taurus, and the Perseus becoming the Hercules. The Taurus was a sleeve valve design, resulting in an extraordinarily uncluttered exterior and very low mechanical noise. It offered high power with a relatively low weight, starting from 1,0 ...

Nevers
Nevers ( , ; la, Noviodunum, later ''Nevirnum'' and ''Nebirnum'') is the prefecture of the Nièvre Departments of France, department in the Bourgogne-Franche-Comté Regions of France, region in central France. It was the principal city of the former provinces of France, province of Nivernais. It is south-southeast of Paris. History Nevers first enters written history as Noviodunum, a town held by the Aedui at Ancient Rome, Roman contact. The quantities of medals and other Roman antiquities found on the site indicate the importance of the place, and in 52 BCE, Julius Caesar made Noviodunum, which he describes as in a convenient position on the banks of the Loire, a depot (''B. G.'' vii. 55). There, he had his hostages, corn and military chest, with the money in it allowed him from home for the war, his own and his army's baggage and a great number of horses which had been bought for him in Spain and Italy. After his failure before Gergovia, the Aedui at Noviodunum massacred t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
