BMW VI
The BMW VI was a water-cooled V-12 aircraft engine built in Germany in the 1920s. It was one of the most important German aero engines in the years leading up to World War II, with thousands built. It was further developed as the BMW VII and BMW IX, although these saw considerably less use. It was also produced in the Soviet Union as the M-17 and Japan as the Kawasaki Ha-9. Design and development The BMW VI was the first twelve-cylinder engine built by the BMW. It essentially consisted of two cylinder banks from the six-cylinder BMW IV bolted to a common cast aluminium crankcase at a 60-degree included angle between the cylinder banks. Series production commenced in 1926 after type approval had been granted. From 1930 on, after 1000 engines of the BMW VI type had already been delivered, Germany was again permitted to construct military aircraft. The sudden additional demand resulted in the production figures increasing rapidly. In 1933 the BMW VI was used for BMW's first exp ...

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. Fo ...

Dornier Wal
The Dornier Do J ''Wal'' (" whale") is a twin-engine German flying boat of the 1920s designed by ''Dornier Flugzeugwerke''. The Do J was designated the Do 16 by the Reich Air Ministry (''RLM'') under its aircraft designation system of 1933. Design and development The Do J had a high-mounted strut-braced parasol wing with two piston engines mounted in tandem in a central nacelle above the wing; one engine drove a tractor and the other drove a pusher propeller. The hull made use of Claudius Dornier's patented sponsons on the hull's sides, first pioneered with the earlier, Dornier-designed Zeppelin-Lindau Rs.IV flying boat late in World War I. The Do J made its maiden flight on 6 November 1922. The flight, as well as most production until 1932, took place in Italy because of the restrictions on aviation in Germany after World War I under the terms of the Treaty of Versailles. Dornier began to produce the ''Wal'' in Germany in 1931; production went on until 1936. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arado SSD I
__NOTOC__ The Arado SSD I was a biplane fighter seaplane developed in Germany in 1930, intended to be launched from catapults on warships. This was an all-new design from Walter Rethel, sharing nothing with his other fighter designs for Arado of the late 1920s. It was a conventional unequal- span, staggered biplane, with the slightly gulled top wing attached to the upper fuselage. It was equipped with a single, large float under the fuselage and two outrigger floats near the wingtips. After evaluation at Travemünde, the floats were removed and a simple, wheeled undercarriage was fitted for competitive evaluation with the Heinkel HD 38 at Lipetsk Lipetsk ( rus, links=no, Липецк, p=ˈlʲipʲɪtsk), also romanized as Lipeck, is a city and the administrative center of Lipetsk Oblast, Russia, located on the banks of the Voronezh River in the Don basin, southeast of Moscow.

Arado Ar 68
The Arado Ar 68 was a German single-seat biplane fighter developed in the mid-1930s. It was among the first fighters produced when Germany abandoned the restrictions of the Treaty of Versailles and began rearming. Design and development Designed to replace the Heinkel He 51, the Ar 68 proved to have admirable handling characteristics on its first flight in early 1934, despite Arado's inability to secure a sufficiently powerful engine for the prototype. Eventually, a Junkers Jumo 210 was installed and the Ar 68 went into production, though not before worries about the unforgiving nature of such a high-performance aircraft almost resulted in the cancellation of the project. The Ar 68 entered service with the ''Luftwaffe'' in 1936 and one of the first units was stationed in East Prussia. Soon, the fighter was sent to fight in the Spanish Civil War, where it was outclassed by the Soviet Polikarpov I-16. Arado responded by upgrading the engine of the Ar 68E, which soon became the '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arado Ar 65
The Arado Ar 65 was the single-seat biplane fighter successor to the Ar 64. Both looked very similar. The only major difference was the use of a 12-cylinder inline engine versus the Ar 64's radial. The wingspan was also increased. The Ar 65 appeared in 1931 and six models were built. The first three 65a-c were prototypes, while the 65d-f were production models. The Ar 65d was delivered in 1933 and served alongside the Ar 64 in the two fighter groups - ''Fliegergruppe'' Döberitz and ''Fliegergruppe'' Damm. In 1935, the Ar 65 was reduced to a training aircraft. Production of the fighter was discontinued in 1936. However, the next year, 12 of them were presented to Germany's ally - the Royal Bulgarian Air Force. The final production total was 85 aircraft. Variants ;Ar 65a: Prototype, powered by a 559 kW (750 hp) BMW VI 7.3 12-cylinder water-cooled engine.

Arado Ar 64
The Arado Ar 64 was a single-seat biplane fighter, developed in the late 1920s. It was among the first fighters produced when Germany abandoned the restrictions of the Treaty of Versailles and began rearming. Design and development The Ar 64 was a derivative of the earlier Arado SD II and Arado SD III, based upon the ''Reichswehrministerium''s ( Reich War Ministry) requirement for a successor to the Fokker D.XIII fighter. The AR 64D and 64E would be the first fighters built in quantity by Germany since the end of World War I. The two differed, as the 64D had a revised undercarriage and a four-blade propeller, and the 64E had a two-blade propeller attached to a direct-drive version of the Jupiter VI radial engine. In the summer of 1932, 20 aircraft of both types were ordered and 19 of them were assigned to the ''Jagdfliegerschule'' at Schleissheim and the ''Jagdstaffeln'' of the ''Fliegergruppe'' Doberitz and ''Fliegergruppe'' Damm.

Albatros L 77v
__NOTOC__ The Albatros L 77v was a German tandem two-seat reconnaissance fighter biplane, four examples of which were built under license for Albatros Flugzeugwerke by Ernst Heinkel Flugzeugwerke in 1928. Based upon the L 76 Aeolus reconnaissance trainer, the aircraft was powered by a 450 kW (600 hp) BMW VI 5.5 water-cooled V12 engine. Like the L 76, the L 77v had a fabric-covered welded-steel fuselage and wooden dual-spar wings with plywood skins supported by N-type struts. It was armed with twin 7.92 mm (.312 in) machine guns in fixed forward-firing positions and a third on a ring mounting in the rear cockpit. Three of the aircraft saw service performing armament trials in Lipetsk in the Soviet Union The Soviet Union,. officially the Union of Soviet Socialist Republics.

87 Octane
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress th ...
