摘要
流体推力矢量(fluidic thrust vectoring,FTV)技术是利用二次流诱导主流偏转、实现推力转向的新型流动控制技术。概述了FTV技术的空气动力学原理,详细综述了FTV技术的应用验证研究进展,对FTV技术未来发展提出了几点建议:开展FTV喷管几何参数的精细化设计以实现高效可靠的推力矢量控制;通过不同层次的系统集成验证加速推动FTV技术的工程应用;探索环量控制机翼(circulation control wing,CCW)和FTV协同控制完全替代活动舵面的最优方案。
Fluid Thrust Vectoring(FTV)technology is a new flow control technology that uses secondary flow to induce mainstream deflection and achieve thrust steering.The aerodynamic principles of FTV technology are summarized.The application verification research progress on FTV technology is reviewed in detail.Some suggestions for the future development of FTV technology are proposed:conduct refined design of FTV nozzle geometric parameters to achieve efficient and reliable thrust vector control;accelerate the engineering application of FTV technology through different levels of system integration verification;explore the optimal solution of circulation control wing(CCW)and FTV collaborative control to completely replace the active rudder surface.
