The invention discloses an underwater glider closed-loop active flow control device based on synthetic jet, and relates to the field of active flow control. The underwater glider closed-loop active flow control device comprises a piezoelectric film vibration type synthetic jet exciter arranged at the rear end in an underwater glider wing, and the piezoelectric film vibration type synthetic jet exciter is electrically connected with a control unit and a sensor in sequence; and a plurality of synthetic jet nozzles are formed in the rear end of the upper surface of the underwater glider win, nozzles are formed in the piezoelectric film vibration type synthetic jet exciter, and the nozzles are located at the positions of the synthetic jet nozzles. According to the underwater glider closed-loopactive flow control device based on the synthetic jet, local or global effective flow changes are obtained through local disturbance, and then the purposes of increasing lift, reducing resistance, improving a flow field, restraining noise and the like are achieved.

    本发明公开一种基于合成射流的水下滑翔机闭环主动流动控制装置,涉及主动流动控制领域,包括设置于水下滑翔机机翼内后端的压电膜振动式合成射流激励器,所述压电膜振动式合成射流激励器依次电连接有控制单元和传感器;所述水下滑翔机机翼上表面后端开设有多个合成射流喷口,所述压电膜振动式合成射流激励器上开设有喷口,所述喷口位于所述合成射流喷口位置处。本发明提供的基于合成射流的水下滑翔机闭环主动流动控制装置,通过局部扰动,获得局部或全局的有效流动改变,进而实现增升减阻、改善流场、抑制噪声等目的。
