Birdstrike is one of the most dangerous threats for flight safety and, therefore, aircraft before being put into operational service have to be certified for a proven level of bird impact resistance. Since the experimental tests are expensive and difficult to perform, numerical techniques are usually used to develop high-efficiency bird-proof structures. In this work, bird strike and (subsequent) penetration inside the airframe are investigated. Different models of bird are considered: advantages and disadvantages of which have been discussed with regard to the impact of a bird against the intake of a turbofan engine.

Abstract

Birdstrike is one of the most dangerous threats for flight safety and, therefore, aircraft before being put into operational service have to be certified for a proven level of bird impact resistance. Since the experimental tests are expensive and difficult to perform, numerical techniques are usually used to develop high-efficiency bird-proof structures. In this work, bird strike and (subsequent) penetration inside the airframe are investigated. Different models of bird are considered: advantages and disadvantages of which have been discussed with regard to the impact of a bird against the intake of a turbofan engine.
