The first experimental coaxial helicopter construction.And.Kamov, who headed at that time, the Bureau of new technology of TSAGI, took to the air in 1947. In 1948 N.

Since 1969, the helicopter Ka-15M were used fibreglass blades and boosted up to 280 BHP engine designed by Ivchenko I. — this gave the opportunity to significantly improve technical characteristics of the car.
