摘　　要：针对氢氧发动机主要性能的敏感性问题,运用敏感性分析方法对影响发动机性能的内外因素进行评估和分析,得到了发动机主要性能对不同影响因素的敏感度。结果表明,相比于其他影响因素,涡轮泵效率水平和调节元件特性对发动机主要性能参数的影响较大,在工程实践中应予以重点关注。Aiming at the performance parameter sensitivity of the hydrogen/oxygen rocket engine, the sensitivity analysis method was adopted to assess and analyze the influence of internal and exter- nal factors on the main characteristics of the rocket engine by means of sensitivity theory and the numerical models. The parameter sensitivity corresponding to different influencing factors was obtained. The analysis result indicates that efficiency of TPA and the characteristic of regulator are the most important influencing factors to the main performance parameters comparing with other factors. The conclusions herewith can be used as a reference of the design and testing analysis.
