摘要

仿真技术是研究液体火箭发动机动态特性的主要手段之一.总结了国内外液体火箭发动机动态特性仿真技术的研究进展,将仿真技术的研究进展分为三个阶段:专用仿真程序阶段、 通用仿真软件阶段和多学科联合仿真阶段.对各个阶段的进展进行了总结和评述,分析了各阶段仿真技术的主要特点.在总结研究进展的基础上,对今后发动机动态特性仿真技术的发展方向提出了设想.%The numerical simulation technology is one of the important methods to investigate the dynamic characteristics of liquid rocket engine ( LRE) . A review on numerical simulation technology of LRE dynamic characteristics is done in this paper. Development of the technology can be divided in-to three stages:special simulation program phase, general simulation software phase and multidisci-plinary collaborate simulation phase. Key work of each developing phase is summarized and evalua-ted. Main characteristics of the simulation technology in each stage are analyzed. Based on summary of the research progress, the development direction of the future numerical simulation technology of LRE dynamic characteristics is proposed.
