Abstract:
A turbojet-engine thrust reverser, comprising:a fan bypass duct having an outlet and a primary engine cowling assembly having an outer wall and a longitudinal axis, said primary cowling assembly located downstream of the outlet of the bypass duct;a plurality of movable thrust deflectors (3) circumferentially spaced about the primary cowling assembly periphery which in a forward-thrust mode are located retracted in a wall of the primary cowling assembly (4), wherein said deflectors (3) are each independently movable relative to the primary cowling assembly and not drivingly connected to another of said thrust deflectors, and each having a downstream portion and an upstream portion;each thrust deflector having a displaceable pivot (12) connected to a downstream portion of a respective thrust deflector and at least one pivotable linkage element (9, 20) connecting each of said deflectors (3) to said primary cowling assembly (4) for rotation about its respective displaceable pivot (12);at least one linear actuator (6) and at least one guide element (10, 30) located in the primary cowling assembly (4), wherein each actuator and guide element associated with a respective thrust deflector are axially aligned with respect to each another, said at least one linear actuator connected to a respective displaceable pivot (12) of said respective thrust deflector and effecting movement of said displacement pivot (12) along said at least one guide element (10, 30) when actuated;each said at least one guide element (10, 30) extending linearly in a fore and aft direction;actuation of each linear actuator (6) and displacement of each displaceable pivot (12) along said guide element (10, 30) in a forward direction relative to engine bypass flow further effecting pivotal and translational motion of a respective thrust deflector (3) in cooperation with said at least one linkage element (9, 20) in a thrust reversed position aft of and adjacent the fan bypass duct to deflect bypass flow forwardly.
