    • 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.

    • 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.
    • 本发明涉及机器结构领域,更准确地说涉及用于飞行器的组合的喷气发动机动力单元。 本发明基本上包括在起飞或亚音速飞行期间主要使用由以标称功率运行的二冲程活塞发动机(4)旋转的风扇(2)来增加空气压力。 风扇(2)产生湍流的加压空气进一步进入燃烧空气燃烧负荷的后燃烧室(7)。 燃烧产物在喷嘴(9)中进一步膨胀以产生飞机推力。 入口装置(1)中的压力增加率与飞行速度一起增加。 一旦达到超音速飞行速度,通过将发动机(4)提供给风扇(2)的力减小,同时保持压力建立,动力单元从马达压缩运行模式切换到冲压喷气发动机运行模式, 上涨比接近1。 该系统在保持风扇(2)旋转的同时最小化功率损失的同时降低了位移的空气阻力。 活塞式发动机(4)驱动器比在这种动力单元上使用的燃气轮机驱动器更经济。 该活塞发动机在其整个操作模式范围内也表现出良好的响应特性,并且允许对飞行模式的任何变化的即时反应,因为风扇(2)可能在飞行中重新启动。 该系统也可以用于避免在经典的ramjets发动机的后燃烧室(7)中的泵送以及火焰爆炸。 在诸如亚音速空气检查或巡航飞行之类的经济模式下,通过关闭燃烧后的燃烧室中的燃料供给,将动力单元切换到具有非常高的旁路比的风扇发动机操作模式。 本发明的方法可以用于以任何飞行速度显着增加飞行器的经济特征,同时由于飞机改进的动态特征而增加飞行的可靠性和安全性。
