Beskrivning:

A U.S. Navy Kellet KH-15 "Stable Mable" in flight. This variable stability helicopter was a flying test-bed developed with the Office of Naval Researchto study the behaviour of a small helicopter in which the significant parameters of the rotor could be altered. It first flew on 13 May 1954 and was fitted with a patented gyro stabilisation system. Although it showed remarkable flight characteristics, it saw no further development.
