EXPERIMENTAL AIRCRAFT

The K-225 served as a prototype for the HTK, the first Kaman helicopter to be evaluated by the U.S. Navy. Kaman was the only U.S. company to mass produce helicopters that incorporated the intermeshing rotor system, a design which eliminated the need for an anti-torque tail rotor. This is one of the first designs used both in military and civilian applications. One K-225 was later re-engined with a gas turbine to become the world's first turbine-engine powered helicopter.

Our K-225 is a generous gift from the Kaman Corporation.
