    摘要: An air breathing reaction propulsion engine has: an open-ended cylindrical combustion chamber having an upstream end and a downstream end, an exhaust propulsion nozzle located at the downstream end of the combustion chamber, and an ejector system located at the upstream end of the combustion chamber. The ejector system comprises an open-ended cylindrical structure having an upstream end through which air is drawn into its interior, and a downstream end in open communication with the combustion chamber. The engine further has a fuel supply system comprising a fuel injector located within the ejector system, a source of pressurised fluid fuel, and a fuel heating coil disposed around the wall of the cylindrical combustion chamber through which the pressurised fluid fuel is supplied to the fuel injector. Under normal running operation, the pressurised fluid fuel is heated in the coil, and the heated fuel is expelled at the fuel injector into the cylindrical structure thereby establishing a pressure differential which draws air into the ejector system to form a combustible fuel/air mixture which is supplied to the combustion chamber. The fuel supply system further comprises a charge-carrying section adapted to carry a charge of a solid fuel which is combusted during start-up operation to produce combustion products that pre-heat the heating coil.

    摘要: The present invention pertains to the field of machine construction and more precisely relates to combined jet-engine power units for aircraft. This invention essentially comprises increasing the air pressure during take-off or subsonic flight mainly using a fan (2) which is rotated by a two-stroke piston engine (4) operating at a nominal power. The pressurised air in which the fan (2) generated turbulence is further fed into an after-burning chamber (7) where an air-fuel load is burnt. The combustion products are further expanded in a jet nozzle (9) so as to generate the aircraft thrust. The pressure build-up ratio in the inlet device (1) increases together with the flight speed. Once the supersonic flight speed is reached, the power unit is switched from a motor-compressed operation mode to a ramjet-engine operation mode by decreasing the force supplied by the engine (4) to the fan (2) while maintaining the pressure build-up ratio close to one. This system reduces the air resistance to displacement while minimising the power losses upon maintaining the fan (2) rotation. The piston-engine (4) drive is substantially more economical than the gas-turbine drive used on such power units. This piston engine also exhibits good response characteristics over the whole range of its operation modes and allows for instant reaction to any change in the flight mode in that the fan (2) may be restarted in flight. This system may also be used to avoid pumping as well as flame explosion in the after-burning chamber (7) which are typical of ramjets engines. During economical modes such as subsonic-speed air inspection or cruise flights, the power unit is switched to a fan-engine operation mode with a very high bypass ratio by shutting the fuel supply into the after-burning chamber. The method of the present invention may be used to substantially increase the economical features of the aircraft at any flight speed, while increasing flight reliability and safety thanks to the aircraft improved dynamic features.
