空间推进系统静态特性通用仿真方法

Versatile numerical simulation on static characteristics of space propulsion systems

针对采用液体推进剂的空间推进系统,提出了一种基于图论和面向对象技术的通用数值仿真方法,该方法适用于空间推进系统各种形式设计方案的检验及推进系统静态工作过程的仿真研究。应用此方法开发的软件对某空间推进系统进行了静态特性的仿真,获得良好效果,显示了很好的通用性。

A versatile numerical simulation method based on the graph theory and object-oriented technique was presented for the space propulsion systems with liquid propellant. The motivation for developing the method is to provide the conceptual-level space propulsion systems designer with a tool capable of providing quick-look answers to systems traditional studies and checking. According to the method, a software written in C++ was developed. It simulated the performance of sorts of space propulsion systems. The results of simulation agree well with available theoretical data. Meanwhile, the software displays very well versatile capability.
