Abstract:
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 external 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.
