| Research Abstract |
To validate our concept of aerodynamic characteristics control for a slender body, wind tunnel tests and numerical simulations have been conducted. In our concept, the separation flow over a slender body is actively controlled by DBD plasma actuator. The wind tunnel tests showed that multi-point installation of the actuators on the body surface could provide proportional control of the pitching moment and the side force. The accurate separation flow structure has been numerically simulated, and meaningful knowledge about the flow structure has been sccessfully obtained for finding more effective control method.
