Kaman HTK-1



Ordered into production for the U.S. Navy at the same time as the HOK-1“off the drawing board ", the HTK-1 also uses the Kaman system of inter-meshing rotors, controlled through servo flaps.
The HTK-1 was delivered to the U.S. Navy as trainer/ambulance, and also adopted as remote-controlled drone. For ambulance work it can carry a stretcher and medical attendant in its cabin, and two casualties on Stokes litters externally, one on each side.
One HTK-1 has been fitted experimentally with two Boeing T50 gas turbines.

During 1958, Kaman completed a research project in which this HTK-1 was flown on electric power. The 240 hp Lycoming engine was replaced by an electric motor of equivalent power, connected to a ground power source by cable.
