Abstract: An improved pivoting door thrust reverser system for a turbofan aircraft jet engine having a non-translatable housing and at least one thrust reverser door being pivotable between a stowed forward thrust position and a deployed reverse thrust position. The thrust reverser door is pivotable about a first axis and a kicker plate is hinged to the door at a second axis. As the door is deployed by an actuator a spring loaded roller clamp means keeps the kicker plate clamped to the actuator body until a portion of the kicker plate positively engages the thrust reverser door and the roller clamp means is then disengaged from the actuator body.

Abstract: A cascade type fan jet engine thrust reverser system. A radially arranged opening is provided along the aft edge the of fan cowl of a fan jet engine. Cascade sets each including a plurality of turning vanes are fixedly positioned in each opening. A blocking door and an actuating linkage system are positioned flush with the inner wall of the fan cowl adjacent to the openings, with the linkage system substantially out of the air flow path during normal engine operation. A sleeve like member covers the outer surface of the cascade sets and at least partially covers the stowed linkage system. When reverse thrust is desired, the sleeve is caused to translate aft, uncovering the cascade set and linkage. The linkage system is caused to move the blocking doors to positions where air flow through the fan cowl is substantially blocked and diverted out through the cascade sets in an outward and reverse direction. Upon completion of thrust reversal operation, these components are returned to the stowed position.

Abstract: A fail-safe pivot door-type aircraft turbine engine thrust reverser which includes a plurality of pairs of pivoting doors on the blocker and deflector sides of openings in a fan jet nacelle. The doors form a flush surface along the nacelle exterior and the fan duct flow path when stowed during normal engine operation in flight. When the doors are deployed in thrust reversing mode, an extensible actuator causes them to translate aft in the opening, with one end of the blocker door moving to at least partially block airflow through the duct and divert it out along the door through the opening uncovered by door deployment. The deflector door pivots outwardly to extend the door length and further direct airflow out and forward along the outside of the nacelle. Upon initiation of deployment, a cooperating pin and track assembly causes the door to initially translate inwardly, then rearwardly, after which the pivoting action begins.

Abstract: A thrust reverser for aircraft fan jet engines using a plurality of sets of deflector and blocker doors filling openings through the engine nacelle during normal engine operation. During thrust reversal, the doors substantially block air normal fan air flow through the duct between engine cowling and the outer nacelle and deflect it out through the nacelle openings in a reverse direction. An actuator and hinge assembly moves each blocker door from a stowed position flush with the inner nacelle surface to a deployed position blocking air flow between nacelle and cowl. Simultaneously, an actuator and hinge assembly moves each deflector door from a stowed position flush with the outer nacelle surface to a deployed position receiving air from the blocker doors and deflecting that air flow in an outwardly and forwardly direction. The actuator and hinge assemblies are substantially out of the path of air flow in both the stowed and deployed positions.

Abstract: An interchangeable frame mounting system is incorporated into an articulated deflector shield assembly for releasable, rigid connection to the hood or radiator grille of a vehicle. The assembly includes a pair of complementary halves each having an elongated C-shaped channel or flange and a rearwardly directed open slot along the length with mating edge portions at adjacent ends of the halves adapted to abut one another. A splice is releasably inserted in the open slots for interconnecting the halves of the frame together. A plurality of brackets at uniformly spaced intervals along each channel includes a leg portion alignable with the slot of the flange and a second leg extends at an angle to the first leg and conforms to the angle of the return portion together with first and second fasteners for releasably interconnecting the first and second legs to the flange and hood, respectively.
