摘要:

在发动机初步设计阶段,要根据对发动机的构型方案进行分析与评价,来选择发动机主要设计参数,并从多个发动机方案中选择最佳方案。作者以液体推进剂火箭发动机为研究对象,建立了一个发动机构型分析与评价软件IRE/CAA。本文阐述了软件LRE/CAA的设计思想,介绍了软件所包括的模块和各个模块的功能,并说明了在软件实现过程中一些问题的处理方法。

Abstract:

In the preliminary design phase of engine, engine configurations must be analyzed and assessed to choose main design parameters and to select optimal engine scheme from multiple candidates. A configuration analysis and assessment software for liquid propellant rocket engine LRE/CAA has been set up by author. This paper explains the main idea in design thinking of LRE/CAA, introduces, software blocks and their function, and illustrates how to deal with some problems in software realizing process.
