Control structure and method for weakening large-flow orbit control jet flow interference based on small-hole jet flow

The invention relates to a control structure and method for weakening large-flow orbit control jet flow interference based on small-hole jet flow, small-hole jet flow is arranged at a proper position of an aircraft model, local high pressure induced by the small-hole jet flow can change model surface pressure distribution and nearby flow field results, and therefore the influence of orbit control interference is reduced, and the stability of an intercepted missile is improved. Small hole jet flow is arranged in a jet flow disturbance area, so that the disturbance force control method is optimal, and compared with an attitude control engine control method, the energy input is small, the interference with incoming flow is small, and the method can also be used as a supplement of the attitude control engine control method. 本发明涉及一种基于小孔射流减弱大流量轨控喷流干扰的控制结构及方法，通过在飞行器模型合适的位置布置小孔射流，小孔射流诱导的局部高压会改变模型表面压力分布和附近流场结果，从而减小轨控干扰影响，提高拦截导弹稳定性。通过在喷流干扰区布置小孔射流，使得干扰力的控制方法达到最优，本发明与姿控发动机控制方法相比，能量输入小，并且与来流干扰小，也可作为姿控发动机控制方法的一种补充。
