The impact of birds against aircrafts and helicopters is not a so remote eventuality, especially during take-off and landing phase and it is one of the biggest economic damage to companies today. To evaluate the effects of this kind of events many experimental tests and numerical models of the phenomenon have been carried out in the last years. The aim of this research work is to numerically analyse the bird impact against oblique target structures. Two case studies are here shown: the impact against a simple plate and against a more complex structure. Different bird models, impact angles and impact velocities were considered. Some considerations on results are finally presented as prescriptions for future works.

Abstract

The impact of birds against aircrafts and helicopters is not a so remote eventuality, especially during take-off and landing phase and it is one of the biggest economic damage to companies today. To evaluate the effects of this kind of events many experimental tests and numerical models of the phenomenon have been carried out in the last years. The aim of this research work is to numerically analyse the bird impact against oblique target structures. Two case studies are here shown: the impact against a simple plate and against a more complex structure. Different bird models, impact angles and impact velocities were considered. Some considerations on results are finally presented as prescriptions for future works.
