Abstract

A ducted fan gas turbine powerplant 10 is located in overlapping relationship with an aircraft wing 12 via a pylon 14. Deflector flaps 22 are provided in the overlapping portion of the powerplant, which are movable soils to cause deflection of fan air which is ejected from the ducted tan, onto the wing upper surface during take off and/or landing of an associated aircraft. The flaps 22 may have trim tabs 26. <IMAGE>
