AbstractApparatus for the synchronized displacement of two thrust reversers for two jet engines of an airplane, comprising first and second systems for displacing respective thrust reversers. Each system includes a compressed air motor, a valve controlling the operation of the motor by controlling the flow of compressed air thereto, and an input system for operating each valve to control the displacement of the respective motor. A synchronizing system synchronizes the displacement of the thrust reversers by measuring displacement in the first and second systems at respective corresponding locations and controlling the operation of the first and second motors such that the displacements of the thrust reversers by the respective motors are equalized.
