ABSTRACT:
An aircraft has a wing10supporting at its underside a gas turbine engine13.A jet pipe14of the engine has an exhaust nozzle15of rectangular flow area defined by upper and lower panels16,17and end walls18.The upper panel, which is a part common to the nozzle and to a trailing edge portion of the wing, comprises a pair of flaps20,21which are pivotal between a position of alignment with the wing10and a position in which they are inclined to the wing. A part of the gas flowing through the jet pipe is diverted through a passage25into a passage26defined between the flaps20,21so as to entrain and accelerate air26A flowing over the wing10.This increases the lift of the wing at the rear thereof and also increases the thrust developed at the nozzle15.This in turn helps to compensate for a nose-up moment on the aircraft arising from the thrust13D2of the engine passing forward of the centre of gravity9A of the aircraft.
