More Information
Summary:A gas turbine engine 100 having a forward thrust mode and a reverse thrust mode is provided. The gas turbine engine includes a variable pitch fan 102 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 110 surrounding the variable pitch fan, wherein the fan cowl forms a bypass duct 112 for airflow generated by the fan. The fan cowl includes an aft edge 128 that defines a physical flow area of the bypass duct, and a deflection device 114 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.
