ABSTRACT:
Apparatus and methods for reducing foreign object debris ingestion into aircraft engines. The apparatus includes a door disposed at a forward end portion of a housing portion of the engine. The door is movable with respect to the engine between a first position in which a first engine inlet is open and a second engine inlet is substantially blocked by the door, and a second position in which the second engine inlet is open and the first engine inlet is substantially blocked by the door. Accordingly, moving the door to its first position during taxiing, takeoff, and landing substantially reduces the risk of foreign object debris ingestion into the second engine inlet.
