ABSTRACT:
A thrust reverser for utilization with wing mounted jet powered aircraft discharging exhaust gases over the wings thereof. The jet engine is housed in a nacelle which is affixed to the forward part of the wing of the aircraft and the nacelle is appropriately contoured for connection to the wing to form part of the aerodynamic profile therewith. A blocker door in stowed condition is contiguous the wing and is similarly profiled. The blocker door is pivotable counterclockwise to a deployed condition wherein it intercepts the airstream before the exhaust gases are discharged through the nozzle. A deflector door is formed in the nacelle in the vicinity of the trailing edge thereof, and it is pivotable clockwise to its deployed condition in which it diverts the gases delivered to it by the blocker door. Separate hydraulic actuators, one associated with the nacelle structure, and one with the wing structure are employed to deploy and stow the blocker and deflector doors.
