The Kaman K-225 was an American experimental helicopter from the first family of designs by Charles Kaman's company, which used two intermeshing rotors steered by his patented servo-flap control. It followed the K-125, Kaman's first helicopter, which flew in January 1947, and the K-190, and it first flew in July 1949 with a 225 horsepower Lycoming piston engine. The United States Navy bought two and the Coast Guard one, and the Air Force evaluated another as the YH-22. In December 1951 a K-225 modified with a Boeing 502 turboshaft engine became the first gas turbine powered helicopter in the world, and that aircraft is now at the Smithsonian Institution in Washington. A standard K-225 is preserved at the New England Air Museum in Windsor Locks, Connecticut. In 1953 the Turkish Army bought one, which was the first helicopter flown in Turkey.
