摘　　要：利用射流主动流动控制方法,飞行器无舵面飞行控制技术取消了传统的机械舵面,具有附加重量小、控制性能优异等优点,适合隐形设计。本文针对现有定常射流控制方法控制效率较低、耗气量大等问题,介绍了振荡射流在无舵面飞行控制中的应用,概述了2项无舵面飞行控制技术——环量控制技术和流体推力矢量技术——的研究现状,讨论了振荡射流在扩大控制区域、增强掺混和频率调节方面的机理和优势。从环量控制和流体推力矢量2个角度出发,详细介绍了振荡射流在无舵面飞行控制中的应用机理和优异表现。The flapless aerodynamic control technology of aircraft has the advantages of low additional weight,excellent control performance and suitability for stealth design by using the active flow control method of jets and eliminating the traditional mechanical flap surface.This paper presents the application of sweeping jets in flapless aerodynamic layouts to address the problem of high air consumption caused by the low control efficiency of existing steady jet control methods.This paper outlines the current research status of two flapless control technologies,i.e.,circulation control and fluidic thrust vectoring,and then discusses the mechanism and advantages of the sweeping jet in terms of control area,enhanced flow mixing,and frequency regulation.The mechanism and performance of the sweeping jet in flapless flight control are presented in detail in terms of circulation control and thrust vectoring.
