摘　　要：S/VTOL(short/vertical take-off and landing)战斗机用推力矢量喷管是飞机实现短距起飞垂直降落,摆脱对跑道的依赖,减小航母的设计难度,及显著提高飞机机动性能的关键技术,已成为第4代战斗机和战斗机用航空发动机的设计标志。结合不同时期推力矢量喷管的特征和不同战斗机对推力矢量的技术要求,对短距起飞垂直降落战斗机用矢量喷管的结构特点、工作原理及发展状况进行了归纳及总结。详细提出了S/VTOL战斗机用推力矢量喷管的关键技术,并对开展S/VTOL战斗机用矢量喷管技术研究提出建议。Thrust vectoring nozzle applied for short/vertical takeoff and landing （S/VTOL） fighters, which has become a landmart design for the fourth generation fighter and aeroengine, is the key technology for aircraft to achieve short takeoff and vertical landing, get rid of the limit of the runway and significantly improve the aircraft maneuvering performance. According to the characteristics of thrust vectoring nozzles in different periods and the thrust vector requirements for different fighters, the structure characteristics, working principle and the development status of the thrust vectoring nozzles for S/VTOL aircraft were summarized and concluded. The critical technologies for thrust vector technology of S/VTOL fighters were proposed in detail, and the suggestions for thrust vector technology research of S/VTOL fighters were also proposed.
