Title: Aircraft in which the exhaust gas is used to energise the airflow over the wing
Inventor: DENNING RALPH MURCH
IPC: B64C1/08
Filed: 1980-11-28
Abstract: An aircraft has a wing structure (11) supporting at its underside a gas turbine engine (13). A jet pipe (14) of the engine has an exhaust nozzle (15) of rectangular flow area defined by upper and lower panels (16,17) and end walls (18). The upper panel, which is a part common to the nozzle and to a trailing edge portion of the wing, comprises a pair of flaps (20,21) which are pivotal between a position of alignment with the wing (10) and a position in which they are inclined to the wing. A part of the gas flowing through the jet pipe is diverted through a passage (25) into a passage (26) defined between the flaps (20,21) so as to entrain and accelerate air (26A) flowing over the wing (10). This increases the lift of the wing at the rear thereof and also increases the thrust developed at the nozzle (15). This in turn helps to compensate for a nose-up moment on the aircraft arising from the thrust (13D2) of the engine passing forward of the centre of gravity (9A) of the aircraft.
