液氮发动机的膨胀过程与参数分析研究

Research on Expansion Process and Parameters' Analysis of Liquid Nitrogen Power System

分析了液氮发动机的膨胀过程与过程参数 ,实现了计算机模拟 ,在选择适当运行参数的情况下 ,采用三级膨胀二次再热过程得到的比功可以达到理想等温膨胀所得到的比功的 90 % ,并且这种膨胀过程是可行的。

The research on expansion process and parameters, analysis of liquid nitrogen power system is introduced. The conclusions obtained here is that the specific energy gained by the three stage expansion two reheat process where some operating parameters to reach 90 percent of that gained by ideal isothermal expansion are selected.
