ABSTRACT
Various bird strike incidents have been reported which pose safety threats to any aircrafts. The wing has been recognised as one of many aircraft structures to be vulnerable to the bird strike. Responsible for an aircraft's lift means that the wing's structural integrity is highly important. With bird strike being rather unpredictable, it is required for the wing to be able to counteract any collisions-minimising damage to both external and internal part of the wing. This research scopes to the modelling and simulating of a wing's leading edge subjected to a bird strike. Modelling and simulations are performed through Finite Element (FE) approach by using ANSYS Workbench. The bird is optimised as a rigid body, having a similar weight to an actual bird. Varying desired parameters of the leading edge-curvature radius (R), skin thickness (T), and number of ribs (N) behind the leading edge provides a better understanding of the extent of each design modification. Six different values of R and T are studied, with one (N1) and two ribs (N2) behind the leading edge's skin considered. Effect of T is seen to exhibit linearly to the amount of Energy Absorbed (EA) and Specific Energy Absorbed (SEA). For R, a peak EA and SEA has been identified. The best configuration, by considering both R and T only, was found to be R5T6 which corresponds to R of 750 mm and T of 2.0 mm. Adding ribs behind the leading edge's skin was also proven to provide more strength. Spacing of ribs is expected to vary the performance, as well as location of impact.
