| 摘 要： | 为了准确分析空气液化发动机为飞行器性能的影响，有必要分析发动机在整个飞行过程中的参数变化。对基本空气液化方案和空气液化分离方案两种发动机进行了构型和系统分析。计算表明空气液化发动机的推力、比冲等重要的总体参数在飞行过程中会有较大的变化。分析数据对全面、准确分析飞行器性能提供了依据。

| Abstract: | System analysis was done to show the relationship between engine parameters and the air flux, for accurate performance analysis of air liquefaction rocket engine. Air liquefaction rocket engine is divided into two parts, their characters are analyzed respectively. The result shows the important engine parameters such as thrust and specific impulse I sp change a lot during the fly process. The data will be useful in vehicle performance analysis. |
