An apparatus comprising is provided including an auxiliary power unit positioned within an aircraft. A reverse thrust assembly is driven by the auxiliary power unit to provide reverse thrust during landing of the aircraft. An air flow surface having a first boundary layer of moving fluid when external air is flowed along the airflow surface which could be a nacelle, pylon or any other aircraft surface. A movable member is configured to move between a first position to direct the boundary layer to the auxiliary power unit during climb and cruise of the aircraft, and to a second position to direct a freestream air feed to the auxiliary power unit during landing of the aircraft. Further, the movable member may switch to a third conduit to extract the boundary layer from the interior surface of an engine air intake to reduce the main engine inlet losses and distortion.
