摘　　要：航空发动机点火系统是保证飞机完成飞行任务的一个重要部件,其研发和制造涵盖多个技术生产领域。介绍了国内外电点火系统的主要体系和发展现状,并根据航空发动机使用条件、起动包线、与燃烧室的兼容性、环境适应性等总体要求及元器件材料和工艺水平,结合发动机电点火系统自身研制特点和技术特征,分析了不同电点火系统的设计原理和性能优势。探讨了电点火系统的发展趋势,并指出变频变能电点火系统是未来主要发展方向。The ignition system, which involves multiple technology areas in development and manufacture, is one of important components for flight task. The design principle and current development of ignition systems were presented. According to the general requirements like use conditions, start envelop, compatibility to combustor and environment adaptability of aero-engine and element material as well as technological lev- el, the design principles and performances of different ignition systems were analyzed based on the develop- ment characteristics and technical features. The trend of ignition system was discussed and it was pointed out that variable-frequency ignition system would be the focus.
