The low and medium speed bird-strike impact damage of sandwich composite structure of drone radome during takeoff and landing is examined by numerical simulations, using nonlinear dynamic finite element analysis software LS-DYNA. For different impact velocities, the aircraft radome’s dynamic responses are obtained and the damage in composite panel is clearly demonstrated. The relations of impact energy, maximum impact force and the damage state are analyzed. The simulation results can provide some references for the aircraft radome design.
