The Damage of Sandwich Composite Structure of Aircraft Radome under Debris-Strike
The low and medium speed impact damage of sandwich composite structure of aircraft radome shield under debris-strike during takeoff and landing along runway is examined by numerical simulations, using nonlinear dynamic finite element analysis software LS-DYNA. For different impact velocities, the dynamic responses of aircraft radome shield 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 design of aircraft radome.
