Abstract
An aircraft has a wingsupporting at its underside a gas turbine engineA jet pipeof the engine has an exhaust nozzleof rectangular flow area defined by upper and lower panelsand end wallsThe upper panel, which is a part common to the nozzle and to a trailing edge portion of the wing, comprises a pair of flapswhich are pivotal between a position of alignment with the wingand a position in which they are inclined to the wing. A part of the gas flowing through the jet pipe is diverted through a passageinto a passagedefined between the flapsso as to entrain and accelerate airA flowing over the wingThis increases the lift of the wing at the rear thereof and also increases the thrust developed at the nozzleThis in turn helps to compensate for a nose-up moment on the aircraft arising from the thrustDof the engine passing forward of the centre of gravityA of the aircraft.
