Abstract
A system for controlling one or more jet engine thrust reversers includes a motor, a speed sensor, and a controller circuit. The motor is coupled to one or more jet engine moveable thrust reverser components for moving the one or more moveable thrust reverser components to at least a deployed position. The speed sensor is operable to sense the a rotational speed of the motor. The controller circuit has an output coupled to the motor for selectively energizing and deenergizing the motor in response to the speed sensor sensing that the rotational speed of the motor is, respectively, at or above a first predetermined rotational speed and at or below a second predetermined rotational speed. The system controls the deployment operation of the jet engine thrust reversers such that unwanted mechanical and electrical loads are avoided.
