This paper shows the numerical prediction of bird strike induced damage on the structure of a typical large airliner inboard flap. The results show that the imposed damage critically depends on bird velocity deflection and impact location. An impact with a 1.8 kg bird, which is used for certification requirements, causes severe damage to the flap skins as well as interior structure. The substructure modelling approach showed excellent results when compared to the complete model, reducing computational time and output file sizes. A number of material models has been considered to correctly simulate bird behaviour, resulting in appropriate EOS material and the typical shape for numerical bird strike analyses. The results of bird model validation show good correlation with theory and other published references.
