Mikulin M-17
The Mikulin M-17 was a Soviet-licensed copy of the German BMW VI V-12 liquid-cooled aircraft piston engine, further developed by Alexander Mikulin and used by Soviet aircraft and tanks during World War II. Production began in 1930 and continued through 1942. More than 27,000 were produced, of which 19,000 were aircraft engines while the rest were used in Soviet tanks of the period. Acquisition and production The Soviets had bought examples of BMW's III and IV engines earlier in the 1920s and bought two examples of the VI engine in 1926 for evaluation. Following successful bench trials of the engine the Soviets decided to purchase a license for it. A deal was concluded in October 1927 after prolonged negotiations. The Soviets paid $50,000 and were to pay 7.5% of the price of each engine produced after the first fifty. In exchange, the German company was to inform the Soviets of all changes to the engine for a period of five years. Soviet engineers and technicians were to be tr ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...

Zenith Carburettor Company (British)
The Zenith Carburetter Company Limited was a British company making carburettors in Stanmore Middlesex, founded in 1912 as a subsidiary of the French . In 1965, the company joined with its major pre-war rival Solex Carburettors, and over time, the Zenith brand name fell into disuse. The rights to the Zenith designs were owned by Solex UK (a daughter company of Solex in France). While better known for its much later products, Zenith produced carburettors that were standard equipment on some very early, brass era automobiles, including the Scripps-Booth. Products Zenith's best-known products were the Zenith-Stromberg carburettors used from 1965–1967 Humber Super Snipe Series Va/Vb, Humber Imperial, 1967–1975 Jaguar E-types, Saab 99s, 90s and early 900s, 1969–1972 Volvo 140s and 164s, 1966–1979 Hillman Minx, Hunter (Arrow), 1966–1970 Singer Gazelle/ Vogue (Arrow), 1967–1975 Sunbeam Alpine/ Rapier Fastback (Arrow), 1970–1981 Hillman/Chrysler/Talbot/Sunb ...

BT-7
The BT-7 BT (russian: БТ) is the Russian abbreviation for "fast tank" (, ). was the last of the BT series of Soviet cavalry tanks that were produced in large numbers between 1935 and 1940. It was lightly armoured, but reasonably well-armed for the time, and had much better mobility than other contemporary tank designs. The BT tanks were known by the nickname ''Betka'' from the acronym, or its diminutive, ''Betushka.'' The BT-7's successor was the famous T-34 medium tank, introduced in 1940, which replaced all of the Soviet fast tanks, infantry tanks, and medium tanks then in service. Development The first prototypes of the BT-7 had a distinctive canted-ellipse shaped turret mounting both the main gun and a coaxial machine-gun. The specification also called for the project to allow for the installation of new guns without any significant change to the framework: the 76 mm KT-26 or PS-3 main gun (a short-barreled howitzer) and the 45 mm 20K model 1932/38, a long-barr ...

Tupolev TB-1
The Tupolev TB-1 (development name ANT-4) was a Soviet bomber aircraft, an angular monoplane that served as the backbone of the Soviet bomber force for many years, and was the first large all-metal aircraft built in the Soviet Union. Design and development In 1924, the Soviet Air Force instructed TsAGI, (Центра́льный аэрогидродинами́ческий институ́т (ЦАГИ) – ''Tsentralniy Aerogidrodinamicheskiy Institut'' or Central Aerohydrodynamic Institute) to design a heavy-bomber. TsAGI gave the task to the division led by Andrei Tupolev.Gunston 1995, p.381. Tupolev's team designed a twin-engined all-metal monoplane with a corrugated Duralumin skin — based on Tupolev's earlier work utilizing the all-metal aircraft design techniques first pioneered by Hugo Junkers in 1918 — powered by two Napier Lion engines, and named the ANT-4.Duffy and Kandalov 1996, p.36. The first prototype was built during 1925 on the second floor of Tupolev's facto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tupolev PS-7
The Tupolev ANT-7, known by the VVS as the Tupolev R-6 ( R – ''razvedchik'' – reconnaissance), was a reconnaissance aircraft and escort fighter of the Soviet Union. The R-6 traces its roots back to early 1928 when the Soviet Air Force needed a long-range multirole aircraft. The requirements were that it could be used for long-range transport, defensive patrolling, reconnaissance, light bombing and torpedo attack. Design and development Under Ivan Pogosski and guided by Andrei Tupolev, TsAGI developed the ANT-7 from the Tupolev TB-1 by scaling it down by about one third. Power for the ANT-7 was intended to be provided by two – Hispano Suiza engines or Bristol Jupiter engines, but the prototype was powered by two – BMW VI engines. The first flight of the ANT-7 took place on 11 September 1929, piloted by Mikhail Gromov. Flight tests started in March 1930 after TsAGi decided to postpone them until after the winter. That summer, the NII-VVS (''Nauchno-Issledovatel' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tupolev ANT-9
The Tupolev ANT-9 (russian: Туполев АНТ-9) was a Soviet passenger aircraft of the 1930s. It was developed as a reaction to the demand for a domestic airliner. At this time Deruluft, one of the forerunners of Aeroflot, flew only with foreign models, which were mainly German or Dutch. Design work began in December 1927. The first prototype, named ''Krylia Sovietov (Wings of the Soviets)'' used three French Gnome-Rhone Titan radial engines. It was presented to the public on 1 May 1929 at Red Square and it went to the national flight testing, which was completed in June. In the first series 12 aircraft were built. In production, the Titan engines were replaced with M-26 engines, but these proved too unreliable and were replaced with imported Wright Whirlwind engines. Two of these airplanes were used by Deruluft, starting from 1933 on the Berlin-Moscow service. Mikhail Gromov accomplished a European round flight on the route Moscow – Travemünde – Berlin – Paris – Rom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polikarpov I-7
The Heinkel HD 37 was a fighter aircraft, designed in Germany in the late 1920s, but produced in the USSR for Soviet Air Force service. It was a compact, single-bay biplane with staggered wings of unequal span, braced by N-type interplane struts. The pilot sat in an open cockpit, and the main units of the tailskid undercarriage were linked by a cross-axle. Design and development It had been designed for the clandestine air force that the ''Reichswehr'' was training at Lipetsk, but had been rejected by German officials, who purchased the Fokker D.XIII instead. The Soviet Air Force was experiencing a crisis with the obsolescence of its main fighter, the Polikarpov I-5, with no replacement apparently forthcoming from domestic manufacturers. When Heinkel was approached to provide an alternative, the firm was able to offer the HD 37, and the two prototypes were flown to Moscow in early 1928. Flight testing produced mixed results. While the basic design was apparently sound, Sovi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
