Closing and locking device for thrust reverser doors

摘要

The mechanism consists of a lock (21) fixed to one part (10) of the flap assembly (12), and an interface (28) on the other part. The lock has a bolt (22) which interacts with the interface to hold the flap in its closed position. The bolt is actuated by a motor (38) which moves it at least in its closing direction. The bolt is able to push the interface in the direction of closure to achieve the closure of the flap by the force applied by the motor. The motor is a rotary one and is connected to the bolt by a reduction gear transmission mechanism (40), so that a substantial effort can be applied to the bolt by a small motor. The transmission can be in the form of a worm gear or screw and nut mechanism.
