Bratukhin B-12
Bratukhin, or OKB-3, was a Soviet aircraft design bureau created in 1940 from within TsAGI to develop helicopters. Headed by Ivan Pavlovich Bratukhin, the bureau built several experimental helicopters over the next decade. Each model had the same basic design of two rotors with separate engines carried on the ends of outriggers to each side of the fuselage. The bureau was dissolved in 1951. Models Produced Bratukhin Omega Original prototype helicopter with two 164 kW engines mounted at the end of outriggers. Bratukhin Omega II Improved version of the Omega, with 261 kW engines and structural strengthening. One example produced, which was flown to an altitude of 3000m in January 1945 and used thereafter for pilot training. Bratukhin G-3 Similar to the Omega II, but powered by 336 kW Pratt & Whitney R-985 Wasp Juniors. Two prototypes were followed by five production aircraft. Four were used for research and one for pilot training. Bratukhin G-4 Similar to the or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TsAGI
The Central Aerohydrodynamic Institute (also (Zhukovsky) Central Institute of Aerodynamics, russian: Центра́льный аэрогидродинами́ческий институ́т, ЦАГИ, Tsentral'nyy Aerogidrodinamicheskiy Institut, TsAGI) was founded in Moscow by Russian aviation pioneer Nikolai Yegorovich Zhukovsky on December 1, 1918. History From 1925 and up to the 1930s, TsAGI developed and hosted Tupolev's AGOS (''Aviatziya, Gidroaviatziya i Opytnoye Stroitelstvo'', the "Aviation, Hydroaviation, and Experimental Construction"), the first aircraft design bureau in Soviet Union, and at the time the main one. In 1930, two other major aircraft design bureaus in the country were the Ilyushin's TsKB (''Tsentralnoye Konstruksionnoye Byuro'' means "Central Design Bureau") and an independent, short-lived Kalinin's team in Kharkiv. In 1935 TsAGI was partly relocated to the former dacha settlement ''Otdykh'' (literally, "Relaxation") converted to the new urban-type set ...
