Bratukhin B-5
__NOTOC__ The Bratukhin B-5 was a prototype Soviet twin-rotor transport helicopter designed by the Bratukhin aircraft design bureau. Development The B-5 was an improved and larger design based on the bureau's earlier G-4, a twin-rotor helicopter, with each rotor driven by an Ivchenko AI-26 radial engine. Each engine was housed in a pod on an outrigger with the related rotor above. The programme was delayed waiting for appropriate engines and the B-5 was not completed until 1947, it only made a few short hops before the programme was abandoned due to vibration and structural flexing. An air ambulance variant, the Bratukhin B-9 was built but was abandoned without being flown.Gunston 1995, p.64. Another variant was the Bratukhin B-10 which had uprated 575 hp (429 kW) engines and was modified for use in the artillery observation role with the military designation VNP (Vosdushnii Nabludatelnii Punk - Aerial Observation Point). The B-10 had three-seat for the crew, the cabin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Bratukhin
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 ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Bratukhin B-11 was a prototype Soviet twin-rotor transport helicopter and the last design of the Bratukhin Bratukhin, or OKB-3, was a Soviet aircraft design bureau created in 1940 from within TsAGI to develop helicopters.

Development The B-11 was similar to the design bureau's earlier B-5, a twin-rotor helicopter, with each rotor driven by an Ivchenko AI-26 radial engine. Each engine was housed in a pod on an outrigger with the related rotor above. Designed for a 1947 air force design competition for a general-purpose helicopter. Two prototypes were built and flown in June 1948, test flights showed a problem with rotor-blade stall at high speed and high resonant vibrations in the whole helicopter. In August 1948 the first prototype was grounded for investigation, but limited testing carried on with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bratukhin G-4
The Bratukhin Omega (also known as the 2MG) was an early Soviet helicopter, the first product of a new Soviet design bureau, OKB-3 that was created from within TsAGI specifically to develop rotary-wing aircraft. Bratukhin's design was a side-by-side twin rotor machine, with each rotor carried on a long outrigger truss. The Omega's rotors were each powered by a separate engine carried in a nacelle also at the end of the truss. Captive trials commenced in August 1941 and revealed severe problems with engine vibration and overheating. Before these could be addressed, however, OKB-3 was evacuated ahead of the German advance into the Soviet Union. Design and development Flight testing recommenced in mid-1942, with the Omega still flying on a tether until early the next year. Free-flight trials confirmed the design as basically sound, so although the engine difficulties were never fully resolved, Bratukhin was convinced that further development along the same general lines would prove ...

Ivchenko AI-26
The Ivchenko AI-26 is a seven-cylinder air-cooled radial engine used in early Soviet helicopters and later used in light utility aircraft. Design and development The AI-26 engine was designed by A.G Ivchenko in 1945 with the early designation M-26, later the designation was changed to AI-26. Like the Shvetsov ASh-21 which is basically one bank of cylinders from the Shvetsov ASh-82, the AI-26 was also influenced by the ASh-82. The AI-26 retained the bore, stroke and displacement of the ASh-21 while incorporating new features peculiar to its role. This similarity allowed the AI-26 to use the same production jigs as the ASh-21 and ASh-82 which reduced costs and simplified production. The engine was envisioned as a helicopter engine, but the early test models lacked the necessary equipment to facilitate this role, such as an auxiliary cooling fan, reduction gears and clutch. The GR suffix means ''"Gelikopter"'', or helicopter. Engine testing was completed by early 1946 and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1940s Soviet Military Utility Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 '' Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Military Helicopters
A military helicopter is a helicopter that is either specifically built or converted for use by military forces. A military helicopter's mission is a function of its design or conversion. The most common use of military helicopters is transport of troops, but transport helicopters can be modified or converted to perform other missions such as combat search and rescue (CSAR), medical evacuation (MEDEVAC), airborne command post, or even armed with weapons for attacking ground targets. Specialized military helicopters are intended to conduct specific missions. Examples of specialized military helicopters are attack helicopters, observation helicopters and anti-submarine warfare helicopters. Types and roles Military helicopters play an integral part in the sea, land and air operations of modern militaries. Generally manufacturers will develop airframes in different weight/size classes which can be adapted to different roles through the installation of mission specific equipment. To ...
