Abstract: 968,069. Deflecting propulsion gases on aircraft. ROLLS-ROYCE Ltd. July 15, 1963. No. 28016/63. Heading B7G. [Also in Division F1] A gas turbine jet propulsion engine comprises compressor means, combustion equipment, turbine means and a jet pipe all arranged in flow series, a passage arranged to receive some of the air compressed by the compressor means, a fixed thrust nozzle arranged to receive air directly from the passage and so arranged that in normal use, it may direct the air substantially vertically downwardly, there being a valve device which is adapted to permit or prevent flow of air through the thrust nozzle. The invention is described with reference to a gas turbine jet engine of the by-pass type which comprises a low pressure compressor 11, a high pressure compressor 12, combustion equipment 13, a high pressure turbine which is connected to drive the high pressure compressor, and a low pressure turbine which is connected to drive the low pressure compressor. The turbine exhaust gases flow through a jet pipe 15 which terminates in a propulsion nozzle 35. A portion of air delivered by the low pressure compressor flows into the by-pass passage 16 from which it may flow either through the shoots 17 to mix with the turbine exhaust gases flowing in the jet pipe 15 or through the downwardly directed thrust nozzle 20 so providing vertical lift. A cylindrical sleeve 24 is disposed within the by-pass passage 16, the sleeve having an aperture 23 and being rotatable by means of a motor 25 so that when the aperture 23 is aligned with the nozzle 20 air is discharged downwardly through the nozzle but when the aperture is moved out of alignment with the nozzle such flow is prevented, and the air flows through the passage 16 and through the shoots 17. A cylindrical sleeve valve 30 having apertures 31 is associated with the shoots 17, the sleeve valve being rotatable by means of a motor 32 and being moved in co-operation with movement of the sleeve valve 24. A pair of deflecting plates 37 is pivotably mounted within the jet pipe and a pair of thrust nozzles 38 are disposed on the jet pipe so that when the deflecting plates 37 are moved to the closed position, the turbine exhaust gases are caused to discharge through the nozzles 38 so producing vertical lift, movement of the deflecting plates being controlled in coordination with movement of the sleeve valves 24 and 30. The arrangement of the deflecting plates 37, thrust nozzles 38 and the vanes 40 disposed therein is described in Specification 813,312.
