A drive motor system is coupled to the landing gear wheels of an air craft via a free wheeling clutch assembly. The drive motor system is energized when the landing gear is extended preparatory for landing either manually or automatically. The drive motor system is controlled to rotate the wheels to have the linear velocity of the periphery of a wheel the same as the ground speed of the aircraft at touchdown. A touchdown sensor stops the drive motor system at touchdown causing the clutch assembly to disengage the wheels when the rpm of the wheel is great...
A landing gear drive system for prespinning a landing wheel of an aircraft prior to landing of the aircraft comprising: (a) free wheeling clutch means attached to each wheel of said aircraft, said clutch means for coupling to said wheel when the rotational speed of said clutch means is equal to or greater than the rotational speed of said wheel and decoupling from said wheel when the rotational speed of said clutch means is less than the rotational speed of said wheel; (b) drive motor means coupled to each of said free wheeling clutch means for rotating ...
