Abstract:

Thrust vectoring technology is a key technology for future aircraft, especially high-maneuverability aircraft. The core component of the technology is the thrust vectoring nozzle. The fluidic thrust vectoring nozzle achieves airflow deflection at the nozzle outlet, and has many revolutionary advantages. It can further derive various functions such as short distance/vertical takeoff and landing and reversing thrust to adapt to more diverse application scenarios. Through decades of research, the fluidic thrust vectoring nozzle has gradually gone through stages such as conceptual conception, preliminary exploration, mechanism research, and engineering experiments, continuously improving its technological maturity and developing towards preliminary engineering applications. This paper focuses on introducing the research achievements of representative domestic and foreign researchers on various fluidic thrust vectoring nozzle in recent years. It explores the development trends and future research priorities of fluidic thrust vectoring nozzle, and points out that it is necessary to further strengthen the research on the mechanism of the internal flow field, overcome key technologies such as multi-objective and multi-disciplinary comprehensive optimization, and the overall matching of the aircraft, engine and fluidic thrust vectoring nozzle. By promoting engineering applications, it is expected to provide a reference for the application of fluidic thrust vectoring nozzle technology.

Key words: exhaust system, thrust vector, fluidic thrust vectoring nozzle, flow control, dual throat
