摘　　要：简述了军用航空发动机的发展历程，介绍了变循环发动机的相关概念，总结了第三、第四代战斗机发动机的结构/性能特点和技术特征，重点分析了第五代战斗机推重比12~15发动机的技术特征。结合自适应发动机技术发展（AETD）项目，预估了三外涵变循环发动机的结构和性能特点，得出了第五代军用航空发动机的性能优势。根据归纳出的军用航空发动机总体性能发展趋势，对未来战斗机发动机的发展进行了展望。The development of military aero-engine and the concepts of variable cycle engine were intro-duced. The structure/performance characteristics and technical features of the third and fourth generation fighter engine were summarized. The technical features of the fifth generation fighter engine with thrust-weight ratio 12~15 were specially analyzed. Combining the development of Adaptive Engines tech-nology （AETD）, the structure and performance characteristics of triple-bypass variable cycle engine were predicted, and performance advantage of the fifth generation fighter engine was concluded. Finally accord-ing to the development of military aero-engine performance, the trend of future fighter engines was summa-rized and predicted.
