IEMN/LEMAC-LICS Magneto-mechanical micro-actuators and active flow control: review of the last 15 years results

Abstract : In this paper, we present an overview of the microjet solutions developed by IEMN/LEMAC-LICS during these last ten years for active flow control in the framework of the GDR "Control of separations", the European FP6 "ADVACT" program, and different projects from DGA, the aeronautic foundation, EADS foundation, and CNRT-R2A. The work within these different research projects has been made in collaboration with the major French and European aeronautic and automobile industrials. The IEMN/LEMAC-LICS solutions are based on Micro-Magneto-Mechanical Systems (MMMS) and concern integrated devices delivering pulsed microjets, continuous microjets with bistable « ON-OFF » actuation, and synthetic microjets. These devices were combined in arrays of 8 to 30 elements distributed near the leading edge of a physical model of air wing, within an engine blade, inside a S-duct, around an engine exhaust and at the rear end of a Ahmed car model. Several wind tunnel experiments were made for separation control, and aero-acoustic control. It was demonstrated that the microjets satisfied the functional specifications defined by the industrial partners. Efficient flow control was obtained. MMMS actuators have demonstrated a good robustness in severe wind tunnel environments (temperature, compressibility, humidity, structural vibrations…).
