摘要
An electric thrust reverser actuation system includes an electric motors that is controlled to operate in both a motoring mode and a generating mode. During normal actuation system operations, the electric motor is controlled to operate in the motoring mode to move one or more moveable thrust reverser components. During a power interrupt event, in which the motor's primary power source is lost, the motor is controlled to operate in the generating mode. The electrical power generated by the motor during its operation in the generating mode maintains the thrust reverser system locking mechanisms in an energized, unlocked condition, thereby preventing damage to system components.
