Abstract
So far quite a few papers have been published on controlling separated flow around wings. However, attempts to establish a self-contained, feedback control system for the separation seem to be just started recently. Fundamental elements of the control system are sensor, actuator, and controller. In order to establish a basis of a smart control system for wing separation, an attempt was made to detect separation flow in use of a new receptor sensor on a slope simulating suction surface of wing. It was found that the output of the sensor worked well as flow-direction discriminator. In the present experiment, flows with and without separation were controlled by using a static, roughness element. Results of the separation experiment gave us important hints regarding specifications of actuators to be developed.
