| 摘 要： | 提出了一种新的液体火箭发动机静态仿真模块化计算方法。该方法按照预定的计算顺序，对发动机系统的各个模块进行迭代计算，并采用拟牛顿法求解系统可调变量。该方法对各种发动机静态仿真具有通用性，可用于分析发动机系统内外干扰因素对发动机性能的影响、发动机静态故障仿真或发动机调整计算。该方法能较大地减少系统未知量数目，求解速度快，精度高。该方法已在计算机上采用面向对象程序设计实现，本文给出了用该程序对某液体火箭发动机进行静态特性计算的结果。

| Abstract: | A new modular method is proposed for static simulation of liquid rocket engine.The modules of the engine system are calculated iteratively in a predetermined sequence,and a modified Newton method is used to find the unknown variables of the system.This method has generality for the static simulatin of liquid rocket engine,and it can be applied to analyzing the effects of the disturbances on the performance of the engine.The number of the system unknown variables can be cut down by using this method,and the solution can be found quickly and accurately.The program based on the method is realized by the object-oriented programming.The static simulation results of a liquid rocket engine are obtained from this program. |
