Abstract
An electromechanical thrust reverser actuation system that is designed with non-symmetric redundant channels is interfaced with an aircraft engine control system that is also redundantly designed. In one embodiment, the engine control system is also designed with non-symmetric redundant channels, and in another embodiment it is designed with symmetric redundant channels.
Claims38
An electromechanical thrust reverser actuation system for interfacing to a jet engine control system having at least first and second engine control system channels, the actuation system comprising:
- a thrust reverser controller having at least two electrically isolated thrust reverser controller channels, each of the thrust reverser controller channels coupled to receive command signals from one of the engine control channels and at least one of the thrust reverser controller channels operable, in response thereto, to transmit thrust reverser motor actuation control signals;
- and
- at least one motor coupled to receive the thrust reverser motor actuation control signals from one of the thrust reverser control channels and operable, in response thereto, to move a thrust reverser between a stowed position and a deployed position.
An electromechanical thrust reverser actuation system for interfacing to a jet engine control system having at least first and second engine control system channels, the actuation system comprising:
- a thrust reverser controller having at least a primary thrust reverser controller channel and an alternate thrust reverser controller channel, each of the thrust reverser controller channels coupled to receive command signals from one of the engine control channels and operable, in response thereto, to transmit thrust reverser lock actuation control signals, and to cause the primary channel to transmit thrust reverser motor actuation control signals;
- at least one thrust reverser primary locking mechanism coupled to receive the thrust reverser lock actuation signals from the thrust reverser controller primary channel and operable, in response thereto, to move between a locked and an unlocked position;
- at least one alternate thrust reverser locking mechanism coupled to receive the thrust reverser lock actuation signals from the thrust reverser controller alternate channel and operable, in response thereto, to move between a locked and an unlocked position;
- and
- at least one motor coupled to receive the motor actuation control signals from the primary thrust reverser controller channel and operable, in response thereto, to move a thrust reverser between a stowed position and a deployed position.
An electromechanical thrust reverser actuation system controller for interfacing to a jet engine control system having at least first and second engine control system channels, the controller comprising:
- at least two electrically isolated thrust reverser controller channels, each of the thrust reverser controller channels coupled to receive command signals from one of the engine control channels and at least one of the thrust reverser controller channels operable, in response thereto, to transmit thrust reverser motor actuation control signals.
