ABSTRACT:
An aircraft bypass turbofan engine subassembly for ground deceleration (e.g., thrust reversal). A fan nacelle has a through passageway connecting its inner exterior surface and outer exterior surface. A passageway end is located on the inner exterior surface aft of the aft-most row of fan rotor blades. A row of pivotable fan outlet guide vanes is located radially between the fan and core nacelles and longitudinally aft of the flow splitter and the passageway end. Apparatus is provided to pivot the vanes to block passage of bypass air and to open the passageway for ground deceleration.
