BRATUKHIN OMEGA 2MG

Cuando la segunda guerra estalló, todos los proyectos de helicópteros pasaron a una sola oficina, en la que el jefe de proyectos era I.P.Bratukhin. El OMEGA fue el primer desarrollo de esta oficina, constaba de dos rotores transversales, cada uno con motores MV-6 con una caja de transmisión que distribuia la potencia, en caso de plantada de uno de los motores, el helicóptero seguia en vuelo sin problemas. El fuselaje era de metal, con una cola en T. El proyecto fue aprovado el 27 de junio de 1940, y la aeronave fue terminada en agosto de 1941, comenzando los test rápidamente. Por problemas por la guerra y la evacuación de la oficina los trabajos fueron detenidos por 1 año. Recien en 1943 comenzaron nuevamente los tests (piloto K.I.Ponomarev), incluyendo los mismos de despegues, aterrizajes, giros de 360 grados, etc..

When the Second World started, all helicopter related jobs were concentrated in a single design bureau (OKV-3) headed by I.P.Bratukhin. The "Omega" helicopter was the first product of this bureau. It wasa twin rotor helicopter of transversal design. Each rotor was driven by separate MV-6 engine linked by a synchronizing shaftsystem. This system also provided the ability to fly helicopter with either engine running. Unlike primitive powerplants of earlier helicopters (see 1-EA ), the engines of "Omega" were equipped with specially designed gearboxes, clutches, and other components typical of modern helicopters. The fuselage had a metal (welded steel tubes) frame with fabric cover. An airplane type T-shaped tail was used for flight control together with main rotors (it was also fully instrumented). The project was approved on June 27,1940. The aircraft was finished in August 1941, and flight tests began (first - on the tie). Evacuation of the OKB-3 facility interrupted work on the "Omega" for 1 year. Only in 1943 did flight tests start again (pilot K.I.Ponomarev). Tests included takeoffs, landings, 360 degree turns while hovering, straight and level flight and sharp turns. Also, the capability of the helicopter to 'glide'safely in autorotation was tested.
