The invention discloses an underwater glider open-loop active flow control device based on synthetic jet, and relates to the field of active flow control. The device comprises a mechanical double-cavity vibration type synthetic jet exciter arranged at the front end in a wing of an underwater glider; the mechanical double-cavity vibration type synthetic jet exciter is electrically connected with acontrol unit, and the control unit is fixedly arranged in the underwater glider; and a plurality of jet nozzles are formed in the front end of the upper surface of the underwater glider wing, and themechanical double-cavity vibration type synthetic jet exciter is located at the positions of the jet nozzles. According to the underwater glider open-loop active 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.
