Abstract

The bird strike incidents have
been a problem since the start of modern aviation. It remains one of the most
dangerous threat to the flight safety. Although catastrophic failure is
uncommon, flight safety authorities require aircrafts to be designed to
complete the flight without any harm. In addition to experimental investigation
of bird strikes, finite element modeling is adopted in numerous researches on
bird strike. A finite element model based on smooth particle hydrodynamics
(SPH) is developed to analyze the bird strike effect on a leading edge of an
aircraft wing. Since birds strike at the leading edge of the wings from
different orientation, bird strike simulations are performed from various
orientations. Results presented in the current work that the advancing angle of
birds toward the leading edge has a minor effect on the deformation of the
leading edge of an aircraft wing.  The
deformation behavior of the wing leading edge after bird strike is discussed in
detail by presenting the results in figures. Simulations illustrated that the
advancing angle of a real bird causes substantial structural deformations on
wing profiles.
