抄録

An attempt was made to construct a self-contained, feedback control system for separation. The fundamental elements of the control system are sensors, actuators, and their controllers. To establish the basis of a smart control system for wing separation, a cantilever sensor (CS) and a control system using it were tested successfully. A fiber Bragg grating sensor (FBG) was tested using a suction-blowing type actuator. In this study, we confirmed that 1) the CS was an effective flow direction discriminator, 2) the closed-loop control system for wall separation with a CS worked well, 3) the present FBG sensor system could measure the flow drags precisely, and 4) the suction-blowing type actuator actually reduced the turbulent skin friction drags.
