Mil Mi-6
The Mil Mi-6 (Russian Миль Ми -6, NATO reporting name " Hook", German: hook ) is a turbine -powered, heavy transport helicopter, which was developed in the Soviet Union.
Development
After three years of development, the prototype completed on June 5, 1957, test pilot Rafail Kapreljan its first flight. This extensive ground testing and not classified as a flight seconds long hops were preceded on March 3. The first public presentation took place during the Tuschinoer flyby on 20 July 1958. The Mi -6 was associated with a total length of almost 42 meters, not only for more than ten years the world's largest helicopter, but also the first Soviet turbine-powered helicopter. During the testing phase, some records could be set up, for example, a payload of 20,117 kg was lifted, a mass that is greater than the unladen weight of the largest non -Soviet helicopter this time, the Sikorsky S-64 Skycrane. Total 1957-1964 17 world records have been set with the Mi-6.
Use
As a military transport helicopter Mi-6 can carry up to 70 soldiers, which can leave the machine quickly through a back split-level cargo area access. Thus, the Mi-6 is also suitable for transporting large military unit or palletized freight. In the civil use of the Mi-6 provides in normal airline seating 65 passengers place up to 120 people can be transported. The internal payload is specified at 12,000 kg.

The Mil Mi -6 was used in large quantities in the work of liquidators after the Chernobyl nuclear disaster in 1986.
Technology
It is characterized, in addition to the outboard -mounted fuel tanks, the stub wings, which contribute up to 20% to the total lift in forward flight. Furthermore, the Mi-6 shows a typical five-petal main rotor, as is known also from other patterns mils Company.
Two gas turbine engines of the type Soloviev D -25W generate a total output of 8090 kW, which allow the helicopter a maximum speed of 300 km / hr. The maximum altitude is 4500 m, with a typical payload of 8000 kg has a range of 620 km will be given. The maximum takeoff weight is 42,500 kg, empty weight 27,240 kg. The length of the helicopter is 41.74 m, the main rotor has a diameter of 35 m and the Mi-6 is 9.86 m high.
