HIGH-VELOCITY BIRD STRIKE ANALYSIS ON AIRCRAFT LEADING EDGE USING SPH METHOD

Abstract

Bird strike poses a major threat to aircraft structural integrity, particularly during takeoff and
landing phases. At high impact velocities, a bird behaves as a soft hydrodynamic body rather than
an elastic solid, producing high-intensity, short-duration loads on aircraft structures.
This study investigates high-velocity bird strike impact on an aircraft leading edge structure using
the Smooth Particle Hydrodynamics (SPH) method. Numerical simulations are performed using
ANSYS AUTODYN and explicit dynamic solvers. The bird is modeled as a soft body using an
appropriate equation of state (EOS), and the leading edge is modeled using carbon fiber composite
material.
