Electromechanical thrust reverser with a permanent position control for an aircraft engine

The thrust reverser has two doors (10a, 10b) moved between open and close positions by a control jack. An electronic calculator (20) has two paths (20a, 20b) connected to respective electronic control units (18a, 18b). The paths receive position data of the doors measured by sensors from the control units and data regarding a state of functioning of each unit so as to exchange position data and each control unit state data.
