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 exper ...

Wolfgang Von Gronau
Hans Wolfgang Gronau, as of 1913 von Gronau (25 February 189317 March 1977), was a German aviation pioneer and Luftwaffe general. During World War II he was the German air attaché and the chief of the Luftwaffe liaison staff in Japan. Biography Wolfgang von Gronau was born in Berlin in a family hailing from the ancient dynasty of the House of Berg. He was the son of artillery General Hans von Gronau (1850–1940) and Luise Gerischer (1867–1926). On 1 April 1911, he joined the Imperial German Navy as an officer candidate where he was put in charge of a flying boat squadron during World War I. After the disbandment of the imperial military in 1919, von Gronau had reached the rank of ''Oberleutnant zur See'', highest lieutenant grade in the German Navy. On 18 August 1930 von Gronau flew on a transatlantic flight on a Dornier ''Wal'' —the old D-1422 flying boat that Amundsen had flown earlier. He took off from Sylt (Germany) through Faroe Islands, Iceland, Greenland and Labr ... [...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, unrelated to his other fighter designs for Arado of the late 1920s. It was a conventional, unequal- span, staggered biplane, with the slightly gulled-winged 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 alongside the Heinkel HD 38 at Lipetsk Lipetsk (, ), also Romanization of Russian, romanized as Lipeck, is a types of inhabited localities in Russia, city and the administrative center of Lipetsk Oblast, Russia, located on the banks of the Voronezh (river), Voronezh River in the Do ....

Arado Ar 68
The Arado Ar 68 was a single-seat biplane fighter designed and produced by the German aircraft manufacturer Arado Flugzeugwerke. It was among the first fighters produced when Germany abandoned the restrictions of the Treaty of Versailles and began rearming. The Ar 68 was a part of Arado's continuing fighter development programme, being designed during the early 1930s as a biplane of relatively standard construction. Both the Rolls-Royce Kestrel and BMW VI selected to power the type proved to be inferior in terms of high altitude performance to the newer Junkers Jumo 210, however, due to limited availability of that only, only late production Ar 68s were outfitted with this powerplant. In addition to its twin 7.92 mm (0.312 in) MG 17 machine guns, some aircraft were provisioned with a compact bomb bay. While the Ar 68 possessed favourable handling characteristics, some officials were concerned that the unforgiving nature of high-performance aircraft would make the ...

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. First flight in 1931. ;Ar 65b: Prototype, similar to the 65a but with minor structural changes. ;Ar 65c: Prototype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arado Ar 64
The Arado Ar 64 was a single-seat biplane fighter designed and produced by the German aircraft manufacturer Arado. It was among the first fighters produced when Germany abandoned the restrictions of the Treaty of Versailles and began rearming. The Ar 64 was developed from the earlier Arado SD II and Arado SD III specifically to equip the so-called 'display squadrons' of the Reichswehr (German armed forces). It was typically powered by a Siemens (Bristol) Jupiter VI air-cooled radial engine, which had a distinctive streamlined deflector shroud around its cylinders to reduce drag. The Ar 64 was the company's first aircraft to be provisioned with hydraulic brakes. The prototype made its maiden flight in the spring of 1930. While the aircraft exhibited unfavourable take-off and landing characteristics, as well as structural weaknesses that could led to it breaking up, the Ar 64 emerged as the favourite and received a production contract, unlike the competing Heinkel HD 43.

Albatros L 77v
__NOTOC__ The Albatros L 77v was a German tandem two-seat reconnaissance fighter sesquiplane, 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; these included one aircraft testing a free-mounted 20 mm cannon. The fourth aircraft had been destroyed while undergoing tests in March 1929. Between December 1929 and their retirement in October 1931, the surviving L 77vs were based at the Staaken ...

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 causing engine knocking. 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 the resistance to detonating under pressure without a spark. Whether 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. The added power in such cases comes from the way the engine is designed to compress the air/fuel mixture, and not directly from the rating of the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
80 Octane
8 (eight) is the natural number following 7 and preceding 9. Etymology English ''eight'', from Old English '', æhta'', Proto-Germanic ''*ahto'' is a direct continuation of Proto-Indo-European '' *oḱtṓ(w)-'', and as such cognate with Greek and Latin , both of which stems are reflected by the English prefix oct(o)-, as in the ordinal adjective ''octaval'' or ''octavary'', the distributive adjective is ''octonary''. The adjective ''octuple'' (Latin ) may also be used as a noun, meaning "a set of eight items"; the diminutive ''octuplet'' is mostly used to refer to eight siblings delivered in one birth. The Semitic numeral is based on a root ''*θmn-'', whence Akkadian ''smn-'', Arabic ''ṯmn-'', Hebrew ''šmn-'' etc. The Chinese numeral, written (Mandarin: ''bā''; Cantonese: ''baat''), is from Old Chinese ''*priāt-'', ultimately from Sino-Tibetan ''b-r-gyat'' or ''b-g-ryat'' which also yielded Tibetan '' brgyat''. It has been argued that, as the cardinal num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
