摘要:

为了提高冲压发动机在更高速度区内的性能,扩展发动机的运行速度范围,需要在并行于发动机的燃烧室处附加一套能量旁路系统。从能量旁路系统技术实现的角度,分析AJAX(俄罗斯学者提出的一种带有能量旁路的冲压发动机)中能量注入方式的缺点,改用电弧式能量注入方式,形成一种新型的高超声速推进系统——磁流体-电弧-冲压发动机(MHD-Arc-Ramjet)联合循环。热力分析表明:MHD-Arc-Ramjet联合循环的单位推力与AJAX是相当的;由于前者可以在更高的温度下进行能量注入,其在单位推力方面是具有优势的。最后对MHD-Arc-Ramjet联合循环的研究工作做了展望。

Abstract:

An energy bypass system located parallel to combustor is applied for the performance improvement at high flight speed and extension of flight envelop. The disadvantage of energyreintroduction in AJAX, proposed by Russian as a special case of ranjet engine with energybypass system, is explored in this paper, and a new hypersonic propulsive system named as MHD-Arc-Ramjet combined cycle is proposed, which uses arc for energy injection.
