  • Patent number: 7370468
    Abstract: A turbojet thrust reverser includes two doors each displaceable between an open position and a closed position of the reverser by at least one respective control actuator. Two electric motors drive the control actuators for the doors; each motor being controlled by an electronic control unit connected to a full authority digital engine control. Two servo-control devices control the displacement of the doors as a function of determined position references. The servo-control devices enable the doors to be displaced synchronously as a function of any variation in the forces exerted on the reverser and as a function of any force difference between the two doors.

  • Patent number: 7278257
    Abstract: A turbojet thrust reverser has two doors that are displaceable between a reverser open position and a reverser closed position, each door being controlled by a respective electronic control unit connected to a FADEC, and each door having a respective locking device for locking the position of the door associated therewith. Each locking device can be unlocked solely on receiving orders that come simultaneously from both electronic control units.

  • Patent number: 6926234
    Abstract: A turbojet thrust reverser includes two doors each controlled by a respective electronic control unit, at least one sensor per door measuring at least one item of position data concerning the door, at least one sensor of each door being connected to the electronic control unit controlling that door, the electronic control units being connected to each other in order to exchange the position data, a FADEC having two channels each connected to both electronic control units in order to receive from each of the electronic control units data concerning the positions of each of the doors and data concerning the operating state of each of the electronic control units, the channels being connected to each other in order to exchange the door position data and the electronic control unit state data so that the airplane pilot is continuously informed about the positions of the doors and the states of the electronic units, even in the event of a breakdown in one of the electronic units and in one of the FADEC channels.
