Abstract: Thrust vectoring can significantly expand the operational envelope of fighter aircraft and improve their flight safety and combat capabilities. A key technology in aerospace study and one of the typical features of advanced fighter aircraft, thrust vectoring involves multiple fields such as aerodynamics, air intake/exhaust, engines, and flight control. The integrated implementation of thrust vectoring is an interdisciplinary, closely-coupled and high-risk systematic project. This paper reviews the development of fighter aircraft thrust vectoring with an analysis of its key technologies. Based on the engineering practice of the first axial-symmetric thrust vectoring demonstrator in China, this paper elaborates the research on high angle of attack aerodynamic design for internal and external airflow, thrust vectoring engines, integrated flight and propulsion control and post-stall maneuvering flight test verification of fighter aircraft and other related key technologies. Finally, the contribution of thrust vectoring technology to the combat effectiveness of fighter aircraft is summarized and its future applications predicted.

Key words: thrust vectoring, high angle of attack aerodynamics, thrust vectoring engines, integrated flight and propulsion control, flight verification
