摘要：

This paper proposes a circulation control device based on dual synthetic jets (DSJs), and its control effect was verified by wind tunnel tests. The experimental pressure and aerodynamic forces were measured to test the control effect of lift enhancement and aerodynamic moment control. After the circulation control is applied, the negative pressure on the suction surface is decreased. Correspondingly, the positive pressure on the pressure surface is increased. The pressure measurement indicated that the pressure distribution trend in a direction favors the lift enhancement. The maximum increment of the lift coefficient was 0.2 when the momentum coefficient was 0.015. The lift-drag ratio was increased by a maximum of 5.4. Applying circulation control before the stall angle of attack can provide stable increments of the roll and pitch moments. In general, the circulation control method based on dual synthetic jets performs well for lift enhancement and aerodynamic moment control.
