| 摘 要： | 采用测压、测力以及流动显示方法研究了头部微三角扰动块对飞机大迎角非对称背涡的主控作用和背风侧单孔位微吹气对背涡空间位置及相应侧向力的控制作用,以此为基础提出了基于微三角块扰动和单孔位微吹气扰动的组合扰动主动控制新技术,并在某飞机模型上进行了验证.实验是在北京航空航天大学D4风洞中进行的.研究结果表明:该组合扰动控制技术能够实现对飞机大迎角非对称侧向力的有效主动控制.

| Abstract: | The control capability of aircraft forebody asymmetric vortices with micro-triangle and the effect of blowing on lee side on asymmetric vortices are discussed in this paper. A new kind of active control technique, the perturbation-combined active control technique, which combines the micro-triangle and micro-blowing perturbation, is proposed on the basis of the above discussion. The test was conducted in the D4 wind tunnel in Beijing University of Aeronautics and Astronautics. The result shows that this perturbation-combined control technique is effective for controlling the side-force of aircraft with a high attack angle. |
