Bird Strike Analysis on Aircraft Wing

Abstract

Bird strike, also known as avian ingestion, is the collision between a bird and an aircraft.Bird strikes have always been a cause of worry in the aeronautical industry: Aircraft both old and new have suffered from bird strikes.Aircraft ingestion occurs when the bird hits an aircraft wing and gets sucked in.Given that the Aircraft Wings moves at a high Speed, bird strike on a Wing causes its displacement into the wing.This leads to a cascading failure, wherein the entire system fails, thereby resulting in a lot of damage.In this article, we intend to investigate the impact of bird on wing and eventually strengthen its' resistance to bird strikes.I. IV.METHODOLOGY A. The blade and the bird are initially modeled in Ansys.B. AUTODYN-3D is used for the collision simulation.C. The bird was modeled as a cylinder with hemispherical ends.D. To replicate the behavior of the actual bird during strike, rubber (density =1000 kg/m3) is selected as the bird material.E. The bird was given a translational velocity range and the wing moves at aircraft speed.F. The resultant stress and deformation patterns of the blade and bird were obtained.
