Abstract:
A system for controlling the movement of a thrust reverser, comprising:an electric motor coupled to receive electrical power from a power source via one or more supply lines and being operable to operate in a motoring mode and a generating mode; one or more moveable actuators coupled to the electric motor and operable to move the thrust reverser between a stowed position and a deployed position in response to rotation of the electric motor; a monitor circuit coupled to the power source and being operable to produce a status signal indicative of an electrical status thereof; and controller circuit coupled to receive the status signal from the monitor circuit and being operable, in response thereto, to control the electric motor to operate in the generating mode when the status signal indicates the power source is deenergized, whereby the electric motor supplies electrical power to the one or more supply lines.
