A methodology for the numerical simulation of bird impact on a novel Leading Edge (LE) structure of a Horizontal Tail Plane is presented. The innovative LE design is based on a ‘tensor skin’ structure, which is an efficient impact resistant design, comprising one or more folded composite sub-laminates, which unfold during the bird impact, providing the required high-energy absorption efficiency. The simulation technique is based on the non-linear dynamic Finite Element PAM-CRASH code and is performed in two steps.
