Abstract

1,090,351. Jet propelled aircraft. ROLLS ROYCE Ltd. Feb. 22, 1966, No. 7796/66. Heading B7G. [Also in Division F2] 'An aircraft power plant supplies pressurized gas to at least one ejector nozzle upstream of a flap so that ambient air is entrained and caused to flow over the flap, the proportions flowing over the upper and lower surfaces being controlled by a valve. As described, a by-pass gas turbine engine is mounted under an aircraft wing, and by-pass air from the engine is conveyed by a duct 20 to ejector nozzles 24, 25 separated by a hollow splitter 21. Ambient air passes to the ejector nozzles through ducts 27, 31 from a duct 32 opening on to the lower surface of the wing 16, and through the interior of the splitter 21 from its ends. The ejectors discharge over the upper and lower surfaces of a hinged flap 11. The duct 32 is closed at the lower surface of the wing by a spring-loaded door 33 which opens automatically when suction is applied by the ejectors. The lower ejector nozzle has a greater flow rate than the upper, but this may be varied by a flap 42. The engine exhaust gases pass through a nozzle 15, and more by-pass air is supplied to flow over the upper surface of the wing.
