| 摘 要： | 根据氦气和氮气在可贮存推进剂中的溶解度与发动机泵入口压力关系，以及对美国上面级火箭“阿金纳”增压系统的分析，计算和研究，对我国可贮存推进剂上面级火箭的发动机泵入口压力要求和增压输送系统进行分析和研究，认为采用氦气增压，我国可贮存推进剂上面级火箭发动机氧化剂泵入口压力要求可以大幅度地降低，较大地提高火箭的运载能力，并提出相应的改进建议。

| Abstract: | This paper attempt from relationship between the helium or nitrogen solubility in the storable propellant and engine pump inlet pressure, as well as analysis, computation and research for the Agena pressurization system of the upper stage rocket of the America to analyze and study engine pump inlet pressure requirements of our country's storable propellant upper stage rocket and the pressurization system. The author considers that adopting the helium pressurization can decrease greatly the engine pump inlet pressure of the upper stage rocket, and considerably increase transport capacity of the rocket. This paper also puts forward a proposal of the corresponding improvements. |
