Abstract
With the development of the aviation industry, the number of civil and cargo aircrafts is increasing. However, birdstrike is a major threat to the aircrafts. In order to conduct the influence study of the bird shape on the birdstrike response for flat blade, four bird shape models, i.e. cylinder, ellipsoid, sphere and cylinder with hemispherical ends are established. Through the birdstrike simulations of bird with different shapes on the flat blades, the maximum displacement of the flat blade, the peak of the impact contact force and the energy absorption of the flat blade are obtained. The results show that the spherical bird causes the most serious damage to the flat blade, and the bird with the shape of cylinder with hemispherical ends is weaker than spherical bird. Cylindrical bird and ellipsoidal bird are comparable, but both are weaker than the former two. Therefore, a spherical bird should be adopted in the numerical birdstrike study of the engine blade to ensure the safety of the engine.
