Whitehead at the wheel of his 60-rotor helicopter of 1911-12, his last aircraft design. It was built for Lee S. Burridge, the founder and president of the Aeronautical Society of America. Contemporary reports stated that a 75 h.p. engine powered the rotating drum which ran the length of the machine, the rotors being driven by the drum via a pulley system.
