Active control of self-excited roll oscillations of LAR wings

Abstract

Large amplitude roll oscillations are inherent to fixed-wing MAVs. This paper reviews our recent works on the suppression of the self-induced roll oscillations of LAR rectangular wings using active flow control techniques. Both acoustic excitation and synthetic jet blowing have been used to attenuate the self-excited roll oscillations. Three rectangular wings, of flat plate, NACA0012 and SD7003-085-88 profiles were tested. It was found that roll oscillations can be completely suppressed and the onset of the roll oscillations can be delayed by active flow control approaches. PIV measurements indicated that the excitations could restore a symmetric vortex flow over free-to-roll wings thus stabilize the roll oscillations.
