Abstract : Bird strikes are a continuing challenge in the aviation industry, especially for aircraft with leading-edge structures. This study uses LS-Dyna, a powerful finite element analysis tool, to investigate the effects of bird strikes on these structures. A detailed FEA model representing the receding leading-edge structure is created and simulations are performed under different bird impact. The resulting structural damage can be carefully analysed to identify critical design parameters that influence resistance to bird strikes. To comprehensively understand the influence of wing design on bird strike resistance, we compare the structural damage of different swept leading edge wing designs. Maintaining consistent parameters across all simulations allows us to isolate the effects of wing design and directly compare structural damage. This comparative analysis reveals which designs are most resistant to bird strikes and provides valuable insight into future aircraft designs. The results reveal that bird strikes can cause substantial structural deformations on wing profiles. Additionally, kinetic energy and stress distribution are analysed, demonstrating the impact of bird strikes on aircraft wing leading edges.
