초록 ▼

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.

대표청구항 ▼

A thrust reverser assembly for use with a fan jet engine having an engine cowl surrounded by a nacelle which forms an angular duct therebetween, which comprises: a plurality of sets of blocker doors and deflector doors located in radially arranged openings in a fan jet engine nacelle, each of said sets of blocker doors and deflector doors includes two narrow blocker doors cooperating with one wider deflector door; said blocker and deflector doors in a stowed position adapted to form positions of the inner and outer nacelle surfaces, respectively, during normal engine operation; blocker door actuator and hinge means for moving the aft end of said blocker doors to a deployed position engaging the engine cowl and for moving the forward blocker door edge rearwardly and outwardly to overlap the aft edge of said opening, to at least partially block air flow through the duct and direct air flow toward said opening; and deflector door actuator and hinge means for moving said deflector door from said stowed position to a deployed position extending outwardly and forwardly of said opening, with the outer end of said blocker door overlapping the inner edge of said deflector door, to smoothly deflect air exiting said opening in an outward and forward direction; all of said actuator and hinge means being substantially out of the air flow path when said doors are in both stowed and deployed positions.
