Heavy transport helicopters Mi-6, Mi-10, Mi-10K.
Heavy transport helicopter is intended for carrying cargo with the maximum weight of 12t, or 61-90 passengers. Modifications of Mi-6 (Mi-10/10K) were used as flying crane helicopters during installation and construction works.
In June of 1957 the crew of test pilot Rafail Kaprelyan were the first to bring Mi-6 to the sky. In 1959-1963 the State Tests were performed followed by introducing Mi-6 into service. Since 1963, the helicopter had been widely used in the national economy.
Transport helicopter Mi-6 is constructed in accordance with the single-rotor configuration with the lifting five-blade fullmetal control rotor and four-blade wooden control rotor. The propulsion unit consists of two turboshaft engines D-25V. In case one of the two failed, the helicopter was capable of continuing the horizontal flight. The torque at the gearbox outlet could reach 60 000 kgf·m. Other countries managed to develop such powerful gearboxes only 17 years later.
In 1959–1980, more than 850 helicopters Mi-6 and its versions were built in Rostov-on-Don, and 50 more helicopters were built in Moscow (1959-1962). The helicopter construction was constantly improved during the manufacturing process. Mi-6 were delivered to Algeria, Bulgaria, Vietnam, Egypt, Pakistan, India, Iraq, China, Indonesia, United Arab Republic, Peru, Poland, Syria, Ethiopia.
Helicopters Mi-6 participated in military operations in Afghanistan, in the rectification of the consequences of the accident at the Chernobyl Atomic Electric Power Station and others.
In 1959–1963 there were 16 world records set using Mi-6. The speed record for a closed-circle flight – 340.15 km/hr – has not been broken up to the present. In some of the record flights, the takeoff weight of the helicopter was more than 48 t. For reference: the takeoff weight of the foreign analogues still does not exceed 34 tons.
