ABSTRACT:
A thrust reverser for jet engines comprising a pair of thrust reverser doors pivotally mounted on an axis which is substantially diametrically positioned with respect to the exhaust nozzle of a jet engine so as to pivot between a stowed position in which the doors are out of the direct path of exhaust of the engine but subjected to the static pressure of the jet engine over substantially the entire length of the doors, and a deployed position in which the doors are in the path of the engine exhaust for deflecting the exhaust and creating a braking thrust, a latch mechanism for securing the doors in the stowed position, a suitable port for directing a portion of the static pressure of the jet engine toward the doors for exerting the static pressure against the doors, an actuator for releasing the latch mechanism so that the doors may pivot to the deployed position, a valve operatively associated with the latch mechanism for relieving at least a portion of the static pressure of the jet engine acting on an upstream portion of the doors when the latch actuator is actuated, the latch actuator being incapable of releasing the latch until the static pressure is relieved from at least a portion of the doors.
