ABSTRACT:
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 greater than the drive system rpm. An automatic control system is described.
