Abstract

928,475. Gas-turbine jet-propulsion plant. ROLLS-ROYCE Ltd. Dec. 27, 1961, No. 46353/61. Class 110 (3). A by-pass type gas-turbine jet-propulsion engine comprises a jet pipe, a by-pass passage, and mixing means for mixing by-pass air from the passage with the jet gases as they flow through the jet pipe, the mixing means comprising at least two ducts which communicate with the interior of the jet pipe, there being valve means which is adjustable to close one of the ducts to the flow of by-pass air therethrough whilst the other of the ducts remains open and allows by-pass air to flow into the jet pipe. The engine shown comprises a by-pass passage 6 and air therefrom discharges into the jet pipe 10 through ten angularly-spaced ducts 20, each duct being crimped at 21, 22, Fig. 3, so as to provide three radially separated ducts 23, 24, 25. Each duct 24 is provided with a butterfly valve 26 which is pivotally mounted on a radially-extending pivot 27, the valves being actuated so as to open or close the ducts 24. Reheat fuel may be supplied to the jet pipe through pipes 28, the pipes having orifices 30 so that fuel is discharged in the region of the outlets of the ducts 24. The engine is provided with a jet-propulsion nozzle 13 also with two branch exhaust ducts 12, only one of which is shown in Fig. 2, valve means in the form of two clam shells 16 being associated with the ducts 12, the clam shells being pivotally mounted at 17 so that they may either close off the branch exhaust ducts 12 or close off the propulsion nozzle 13 and open the branch ducts 12. Each branch duct 12 is provided with a rotatable frame member 18 whereby the gases may be discharged forwardly, downwardly or rearwardly, this arrangement being described more fully in Specification 913,312.
