摘　　要：本文提出了一种新的液体火箭发动机功率平衡通用计算方法。该方法按照预定的计算顺序，对发动机系统的各个部件进行迭代计算，采用拟牛顿法求解系统可调变量。该方法对各种发动机系统方案的分析具有通用性，适用于液体火箭发动机系统循环方案论证。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采用液氧、丙烷作为推进剂的分级燃烧循环进行计算的结果。A general method for the cycle power balance calculation of the liquid rocket engine is proposed in this paper.The components 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 is universal for the analysis of liquid rocket engine cycles.The program based on the method is achicved by the object oriented programming.The stage combustion cycle using the liquid oxygen and methane as propellant is calculated with the program,and the calculation results are also given.
