Abstract

950,015. Vertical take-off and landing aircraft. ROLLS-ROYCE Ltd. Sept. 13, 1962 [Sept. 20, 1961], No. 33726/61. Heading B7G. [Also in Divisions F1 and G3] A power plant comprises a plurality of gas turbine engines, each of which is provided with a bleed air passage which is arranged to receive part of the air which has been compressed by the engine, there being a common duct with which each of the bleed air passages communicates by way of a bleed air valve, a valve control device being provided for each bleed air valve. Each valve control device (see Divisions F1 and G3) ensures that the bleed air valve is respectively maintained in closed and open positions when the ratio of the pressure in the bleed air passage to that in the common duct is respectively below and at or above a predetermined value, the arrangement being such that when a bleed air valve is in the closed position, the amount of air bled from the respective engine is reduced so as to permit the engine to speed up and the pressure in the respective bleed air passage to rise. The invention is described with reference to an aircraft power plant comprising a group of vertical lift gas turbine engines, each engine having a bleed air conduit, the air conduits supplying into a common duct from which air is supplied to nozzles for controlling the attitude of the aircraft.
