摘要： A rocket engine comprises first and second rotary injectors for injecting respective fuel and oxidizer propellant components into a first combustion chamber, and the effluent therefrom drives a turbine that rotates the rotary injectors. The mixture within the first combustion chamber is preferably fuel-rich so as to reduce the associated combustion temperature, and the fuel-rich effluent mixes in a second combustion chamber with additional oxidizer injected by a third rotary injector so as to generate a high temperature effluent suitable for propulsion. The rotary injectors are adapted so as to isolate the low pressure propellant supply from the relatively high pressures in the respective combustion chambers.

摘要： A multiple fluid feed system for, for example, a turbine engine, comprises a fuel tank, a fuel pump, and means for switching fuel flow from said pump between a return to tank condition and an engine supply condition. A starting fuel reservoir has a cylinder with a fuel inlet and a fuel outlet. A piston in the cylinder is movable from a start position to a run condition in response to movement of the switching means from the return to tank condition to the engine supply condition. A supply of starting fuel is disposed in the reservoir and is biased out of the reservoir upon initial movement of the piston.
摘要翻译：用于例如涡轮发动机的多流体供给系统包括燃料箱，燃料泵，以及用于在回返罐状况和发动机供应状态之间切换来自所述泵的燃料流的装置。起始燃料储存器具有带有燃料入口和燃料出口的气缸。响应于开关装置从返回罐状态到发动机供应状态的移动，气缸中的活塞可以从起始位置移动到运行状态。起始燃料的供应设置在储存器中，并且在活塞初始移动时被偏压出储存器。
