DV10407A 13DV-10407 ABSTRACT An aircraft gas turbine engine is provided with an electrically powered boundary layer air bleed apparatus for bleeding boundary layer air off the nacelle and the wing or another part of the aircraft outer skin in order to reduce boundary layer or surface drag and using the boundary layer air as a source of compressed air and cooling air for the aircraft's environmental control system (ECS). A more particular embodiment of the invention provides means for ducting a portion of the boundary layer air to be further used to produce thrust and reduce base pressure drag in low pressure regions of the aircraft and engine.
