| 摘 要： | 为了考察氢氧发动机参数选择对可重复使用运载器性能的影响,基于氢氧发动机参数建立了可重复使用运载器入轨飞行过程的计算模型,包括运载器运动方程、飞行控制条件和质量模型,研究了发动机混合比对运载器飞行参数和运载器质量的影响规律.在运载器总质量恒定的情况下,随着发动机混合比由4增大到14,推进剂质量和发动机质量先减小后增大,储箱质量减小,三者的综合效果使得有效载荷质量先增大后减小.

| Abstract: | In order to investigate the influence of hydrogen engine parameters on launch vehicle performance,the mathematical models suited for single stage to orbit reusable launch vehicle flight process were brought up based on hydrogen engine performance parameters,including rocket motion equations,flight control conditions and vehicle mass model.The vehicle mass variety rules were discussed in detail changed with hydrogen engine mixture ratio during flight to orbit.The results show that on the condition the vehicl... |
