摘要：A method of engaging a drive system with a rotating wheel of an aircraftlanding gear. A motor is operated to apply torque to a pinion so the pinion rotates andmoved from a neutral position to a contact position in which it contacts a rotating drivengear at an initial contact time, the rotating driven gear being mounted to a rotating wheelof an aircraft landing gear. After the initial contact time the pinion is moved further to ameshing position where the pinion meshes with the driven gear. A centre-to-centredistance between the pinion and the driven gear reduces as the pinion moves to thecontact position and to the meshing position. The driven gear contacts the pinion in aseries of impacts as the pinion moves from the contact position to the meshing position,each impact induces a spike in electromotive force or angular velocity at the motor. Oneof the spikes is detected and the motor is operated to vary the torque applied to thepinion in response to the detection of one of the spikes.
