Abstract: A thrust reverser system suitable for a high-bypass turbofan engine of a type having a nacelle. The thrust reverser system includes a transcowl having a stowed, deployed and open positions. A hinge assembly translationally and rotationally couples the transcowl to a fixed structure that does not translate when the transcowl is translated in the aft direction. The hinge assembly includes a first member connected to the transcowl for translation therewith, and a fixed second member that defines a channel in which a portion of the first member is slidably received. The first and second members are configured to enable the portion of the first member to translate within the slider channel in an aft direction corresponding to a translational movement of the transcowl, and to enable the portion of the first member to rotate within the channel corresponding to a pivotal movement of the transcowl.

Abstract: A gas turbine engine having a centerline axis is provided. The gas turbine engine includes a fan and a fan cowl assembly surrounding the fan to define a bypass duct configured to channel airflow for the fan. The fan cowl assembly includes a stationary cowl and a transcowl. The gas turbine engine further includes a plurality of actuators configured for displacing the transcowl relative to the stationary cowl. Each of the actuators is skewed relative to the centerline axis of the engine.

Abstract: A gas turbine engine having a forward thrust mode and a reverse thrust mode is provided. The gas turbine engine includes a variable pitch fan configured for generating forward thrust in the forward thrust mode of the engine and reverse thrust in the reverse thrust mode of the engine. The engine also includes a fan cowl surrounding the variable pitch fan, wherein the fan cowl forms a bypass duct for airflow generated by the fan. The fan cowl includes an aft edge that defines a physical flow area of the bypass duct, and a deflection device configured for deflecting airflow near the aft edge, wherein the deflection device is configured for operation in the reverse thrust mode of the engine. The physical flow area of the bypass duct at the aft edge remains the same in the forward thrust mode of the engine and in the reverse thrust mode of the engine.
