A study on attenuating the self-induced roll oscillations of low-aspect-ratio flat-plate wings was conducted experimentally in a wind tunnel facility using a bionic flow control approach of the sinusoidal leading-edge (SLE). It was found that the effectiveness of the SLE on roll attenuation strongly...
