The low and medium speed impact damage of composite structure of wing leading edge under hail impact is examined by numerical simulations, using nonlinear dynamic finite element analysis software LS-DYNA. For different impact velocities, the dynamic responses of wing leading edge are obtained and the damage in composite panel is clearly demonstrated. The relations of impact energy, maximum displacement and the damage state are analyzed. The simulation results can provide some references for the design of wing leading edge.
