摘　　要：为了研究不同燃料对火箭基组合循环(rocket based combined cycle,RBCC)发动机总体性能的影响,建立了RBCC发动机准一维总体性能仿真模型,分别研究了以液氧煤油、过氧化氢煤油、液氧甲烷和液氧液氢为燃料的RBCC发动机推力和比冲性能。结合飞/发一体化性能分析模型,研究了不同燃料发动机性能对完成飞行任务能力的影响。结果表明:氢燃料RBCC发动机引射模态推力是煤油燃料RBCC发动机的1.3倍;氢燃料RBCC动力飞行器巡航距离最远,为4 470 km;相同的飞行器参数下,过氧化氢煤油燃料RBCC动力飞行器机动性最大。本方法可为RBCC发动机总体性能方案设计和燃料选取提供参考。In order to study the impact of different fuels on the overall performance of rocket based combined cycle(RBCC) engines,a quasi-one-dimensional overall performance simulation model of RBCC engines was built.The thrust and specific impulse performance of RBCC engines fueled with liquid oxygen kerosene,hydrogen peroxide kerosene,liquid oxygen methane,and liquid oxygen liquid hydrogen were studied.Combined with the integrated aircraft engine performance analysis model,the effects of different fuel engine performance on flight mission capability were studied.The results showed that at ejector mode,the thrust of hydrogen fuel was 1.3 times greater than kerosene fuel;the hydrogen fueled RBCC engine had the farthest cruising distance of 4 470 km;under the same aircraft parameters,hydrogen peroxide kerosene fuel RBCC powered aircraft had the highest maneuverability.This method can provide a reference for the overall performance scheme design and fuel selection of RBCC engines.
