Jeff's Helicopter Philes

Nicolai Kamov started build his first rotor-winged aircraft in 1929, together with N.K.Skrzhinskij . Up to the 40s, they created few more autogiros, including the only (in the World) armed one (A-7-3) that saw (limited) combat action. Since then, the Kamov bureau is specialised on compact helicopters of coaxial scheme, suitable for naval service and high-speed operations.
