Abstract

Collisions between a bird and an aircraft, known as “bird strike event” is a common and dangerous phenomenon in aviation industry. In this study, three numerical methods namely Lagrange, Smoothed Particles Hydrodynamics (SPH) and Arbitrary Lagrangian Eulerian (ALE) have been implemented in order to investigate bird strike incident. The results have been compared with each other and also with exeperimental data. In order to compare the results obtained from three methods, pressures at the center of impact and also deformation of bird models have been compared. Results indicate that all the three methods are able to predict the pressure at the center of impact almost accurately in both perpendicular and inclined impacts. In addition to that all the methods are able to predict same deformation of bird at particular time intervals. Shorter solution time, not having much parameters to deal with and low probability of numerical errors make the SPH METHOD as a good candidate to analyze bird strike problems.
