| 摘 要： | 全隐身布局飞行器采用无尾飞翼布局,此种布局具有很多优点,但是在动态特性上存在一些新的问题,造成了飞行器稳定和操纵的困难.通过对小展弦比飞翼布局飞机进行涡流控制,可以产生较大的控制力矩,从而对飞机进行纵向和航向的控制,改善飞机的操纵效率.控制力矩是非线性变化的,其大小与飞机飞行状态(迎角、速度等)以及喷流的状态(喷流速度、喷孔位置、喷流方向等)有关.将喷流产生的控制力矩应用于飞机的控制,通过对增加喷流后飞机静操纵特性的分析,表明其改善了飞机静操纵特性和隐身性能,具有较好的实用性.

| Abstract: | Because the flying wing aircraft with low aspect ratio cancels the traditional stabilizers and control surfaces which are used in traditional configuration,many disadvantages of dynamic characteristic arise.The goal of this research is through vortex control over low aspect ratio flying wing to overcome some disadvantages.Vortex control could provide a large fore and moment,which could be used to manipulate airplane.The moment is nonlinear,and varies with the fly state and injection state such as attack ang... |
