摘　　要：推力矢量控制技术的喷管实施方案普遍存在着结构复杂、质量重和可靠性设计难度高等问题,而固定几何气动矢量喷管技术因具有不变的几何结构和巧妙的流体控制方式,有望得到结构简单、质量轻和高可靠性的矢量喷管。综述了该技术的设计原理、特点以及国内外的技术现状和发展趋势,并认为先进推力矢量喷管技术的设计和应用应从深入研究主次流参数对喷管性能的影响、引气对发动机主机的影响、喉道调节范围的合理确定、应用技术研究和新型流体控制技术的开发等多角度进行固定几何气动矢量喷管的技术研究。该技术具有较好的未来发展前景。The similar disadvantages include complicated structure, low reliability andoverweight in the nozzle project for thrust vectoring control technology. But the fluidic control fixed geometry nozzle technology has fixed geometry structure and subtle fluidic control method which can meet to simple structure, high reliability and light weight. The design principle, characteristics and the status and the development trend in the world were summaried. The design and application of the advanced thrust vectoring nozzle technology should be investigated deeply which include the effect of the aerodynamic parameters of main and secondary flow path on nozzle performances, the influence of the secondary flow path on aeroengine, research of optimum aerodynamic throat modulation range, the application of fluidic control fixed geometry nozzle and the new method of fluidic control. The technology will have better development.
