FIELD: aviation.
SUBSTANCE: invention relates to a method of engaging a drive system with a rotating wheel of an aircraft landing gear. Motor is operated to apply torque to a pinion. Engagement command is issued to an actuator at certain time. In response to the command, the actuator moves the pinion from a neutral position to a contact position. Rotating driven gear is mounted to a rotating wheel of an aircraft landing gear. Actuator is actuated to move the pinion further to a meshing position. Centre-to-centre distance between the pinion and the driven gear reduces as the pinion moves to the contact position and to the meshing position. Motor is operated to reduce the torque to below a predetermined level at or after the engagement time, maintain the torque below the predetermined level during a spin-down phase until the initial contact time. Then after the initial contact time, the torque is increased above the predetermined level.
EFFECT: reduced tyre wear during landing.
