Flown for the first time in the Spring of 1958, the K-17 is the product of U.S. Army and Kaman cooperation. The helicopter is a cold tip jet system; the engine sends compressed air to the tip-jet nozzles. The main rotor is flap controlled and the ducted tail rotor is controlled by hydraulic power, allowing change in direction.
