The invention belongs to the field of aerodynamics, and particularly relates to a combined high-pressure jet type circulation control system and method.The combined high-pressure jet type circulation control system comprises a circulation control device and a jet device; the jet device comprises jet outlets and high-pressure air chambers which are arranged on the upper side and the lower side of the rear edge end face of the wing; the circular rector control device comprises a Coanda curved surface piece and a driving mechanism. An outer Coanda surface is arranged at one end of the Coanda curved surface piece, and concave cavities are formed in the upper side and the lower side of the other end of the Coanda curved surface piece; the driving mechanism drives the Coanda curved surface piece to move in the vertical direction of the wing, so that the concave cavity is opened, blocked or communicated with the corresponding jet flow outlet; switching of a positive circulation control configuration, a negative circulation control configuration and a non-circulation control configuration can be achieved, combined flow control of reverse jet flow and Coanda jet flow on wing streaming is achieved, the effects are superposed, and compared with traditional single Coanda jet flow or reverse jet flow control, the efficiency is higher. The problem that the circular rector control capability is remarkably reduced after the flight speed of the aircraft is increased is solved.
本发明属于空气动力学领域,具体是涉及到组合高压射流式环量控制系统及方法,包括环量控制装置以及射流装置;射流装置包括设置在机翼后缘端面的上下两侧的射流出口和高压气室;环量控制装置包括柯恩达曲面件和驱动机构;柯恩达曲面件在一端设置有外柯恩达面,在另一端的上下两侧均设置有凹腔;驱动机构驱动柯恩达曲面件沿机翼的上下方向移动,使凹腔打开、封堵或连通相对应的射流出口;本发明能够实现具有正环量控制构型、负环量控制构型和无环量控制构型的切换,实现逆向射流和柯恩达射流对机翼绕流的组合流动控制,效果叠加,相比于传统的单一柯恩达射流或逆向射流控制的效率更高。解决飞行器飞行速度增大后环量控制能力显著下降的问题。
