Feedback Control of Flow Separation Using Plasma Actuator and FBG Sensor

Figure 19

Pictures of feedback control system constructed in a 1 kW-class wind turbine. (a) String-type DBD plasma actuator attached to the suctions surface of a turbine blade made of CFRP. Power transmission and FORJ system is connected to a rotary shaft near the tail of nacelle. (b) Pictures under illumination and (c) without ambient illumination. DBD plasma is formed around the copper wire coated with PTFE not only on copper tape, but also on CFRP surfaces.
