Because of its high stealth and high aerodynamic efficiency, the low-aspect-ratio flying wing layout has become an advanced fighter development platform. The particularity of the layout reduces the lateral stability, which makes it face the instability of wing rock, and affects the maneuverability and flying quality of the aircraft. Therefore, it is necessary to study the wing rock characteristics of the low-aspect-ratio flying wing layout. Through various wind tunnel tests, the wing rock characteristics of the standard wing of the flying wing with low aspect ratio are comprehensively analyzed. The results show that there are sudden stall problems such as wing rock and wing drop in the low aspect ratio flying wing configuration, which are mainly due to the stable equilibrium point of zero-crossing of the rolling moment coefficient near the wing rock equilibrium position, and the zero-crossing of the rolling damping derivative. At the equilibrium point, the slope of the rolling moment coefficient is negative and stable.
