FE Model for Bird Strike Simulation on ARALL Leading Edge

Abstract

This paper deals with the development of a finite element (FE) model for the simulation of a bird strike event on an innovative leading edge made of ARALL (ARamid ALuminum Laminate) material. To assess the reliability of the FE analyses, a preliminary model is developed aiming to simulate a tensile test, according to literature, involving ARALL specimens. Such model provides a good level of accuracy. So, the same modeling technique has been used for the bird strike simulation. Finally, the structural response of the ARALL leading edge has been compared against a conventional Aluminum one. Such a comparison has highlighted the capability of ARALL material in withstanding bird strike events with an improved performance.
