摘要:
分析了适应升力体外形和矩形流道的RBCC动力系统的推阻特性及其影响因素。矩形流道RBCC动力系统推阻力主要包括：进气道产生的风阻力与升力、火箭发动机推力室产生的推力、燃烧室流道的流动阻力、壁面压力产生的推力及尾喷管产生的推力与升力等。影响动力系统推阻力的主要几何因素有进气道构型与迎风面积、支板/凹腔的构型与尺寸、燃烧室流道的型面与扩张角及尾喷管的构型，来流的动压及气体黏度、燃气物性及燃烧室燃烧效率等也会对其产生影响。高性能RBCC动力系统研发需要考虑进气道、火箭发动机推力室、燃烧室、支板、凹腔、尾喷管等部件的优化设计，以及部件间的相互协调。
Abstract:
The thrust/resistance characteristics of RBCC power system adapting to rectangle section flow passage and its influence factors are analyzed. The thrust and resistance of RBCC power system consist of inlet wind resistance and lift, rocket engine thrust, ramjet combustion chamber wind resistance and thrust that produced by gas pressure on flow passage wall, as well as nozzle thrust and lift. The chief factors that affect RBCC power system thrust and resistance are air inlet configuration and wind area, structure and dimension of pylon/cavity, molding surface and divergence angle of combustion chamber, and configuration of nozzle as well. Besides, the thrust and resistance are affected by dynamic pressure and viscosity of incoming flow, gas form and ramjet combustion efficiency. To improve thrust performance of RBCC, all units (inlet, rocket, pylon, cavity and nozzle) should be
