Abstract: The invention relates to a method for controlling an electric motor actuating a mobile hood provided in a thrust reverser for a turboreactor, said method being characterized in that it comprises steps of: determining the operating state of the electric motor; interrupting the supply of the electric motor if said motor is not in operation during a defined period of time; reactivating the electric motor after an idle period and repeating the previous steps or definitively stopping the motor if the steps have already been repeated a pre-defined number of times. The invention also relates to a method for managing the electrical supply of a motor provided in a device arranged in the vicinity of a turboreactor.

Abstract: The invention relates to a control method for opening or closing a turbojet engine thrust reverser (1) by using at least one mobile cowl (2) displaceable by means of at least one electric motor (7) consisting in analyzing at least one parameter representative for a pressure in the turbojet engine jet and in carrying out an operating sequence in which the operating parameters of the electric motor (7) are adjusted to a situation.

Abstract: A device that is capable of actuating at least two cowls of a thrust reverser. The device includes for each cowl, (a) at least two actuators suitable for opening and closing the cowl, (b) at least one slave flexible transmission shaft establishing mechanical connection between the two actuators of the cowl and (c) at least one mechanical coupling device associated to the at least one slave flexible transmission shaft. The device is further comprised of one motor, and at least two master flexible transmission shafts, each master flexible transmission shaft establishing mechanical connection between the motor and one respective mechanical coupling device. Upon rotation of the electrical motor, the master flexible transmission shafts are actuated, which causes actuation of the mechanical coupling devices, which causes actuation of the slave flexible transmission shafts and thereby the extension or retraction of the actuators.

Abstract: A thrust reverser having an annular duct bounding a bypass flow and including a set of vane cascades configured in a stationary pod portion, a displaceable fairing slidably mounted on the stationary pod portion to permit sliding motion along a slotted cylindrical shell and to be translated between a stowed position blocking access of the bypass flow to the vane cascades and a deployed position wherein the vane-cascades are exposed to the bypass flow, a drive system driving the displaceable fairing, and flaps arranged to seal the annular duct in order to deflect a flow toward the vane cascades. The drive system further includes linear actuators substantially configured in the central axis of the slotted cylindrical shells.
