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.
