Abstract

861,101. Jet propulsion plant. UNITED AIRCRAFT CORPORATION. Sept. 2, 1958 [Sept. 3, 1957], No. 28157/58. Class 110 (3). A combined aircraft power plant comprises a central duct having a forwardly projecting cowl surrounding a faired plug to define an opening leading to a turbine-type power plant, means for moving the plug and cowl relatively to one another to vary the area of the opening and an annular duct surrounding the central duct containing a ram jet type power plant. The combined power plant shown comprises a central main duct 12 and an outer annular duct 14. The duct 12 is formed by a plug 16 and a wall 18 and the duct 14 by the walls 18, 20. The duct 12 contains a turbine-type power plant having a compressor 22 which may be driven by any suitable turbine. In one arrangement described the turbine is supplied with working fluid by a combustion chamber to which a fuel and oxidizer or a monofuel are fed. Fuel is injected at 24 into the duct 14 so that it may operate as a ram jet. A movable cowl 30 surrounds the upstream end 28 of the plug 16. In the position shown, air is supplied to the turbine type engine and the duct 14 is shut off. By moving the cowl rearwardly the inlet to the turbine type engine may be closed and the inlet to the duct 14 opened. A reheat combustion chamber 46 and variable area convergent-divergent nozzle 48 may be provided. In a modification, Fig. 2 (not shown), the central duct is extended to the exit plane of the nozzle and provided with a movable bullet so that the turbine-type power plant may be completely closed off. The exhaust of the ram jet in this case is a fixed configuration convergent-divergent nozzle. In another modification, the leading edge of the casing 20 is straight so as to reduce drag. In this case, some air will always flow through the duct 14. In another modification, the turbine type engine is of the gas turbine jet-propulsion type.
