Investigate the Crashworthiness of high-velocity bird impact on three
different designed model wings by using Coupled Eulerian-Lagrangian
approach
Abstract
Bird strike is a significant threat to the parts of the flying
aircrafts. The wing is a central part, which provides stability to the
aircraft. Mostly at wing, bird attack the leading edge. Worldwide
aviation regulation FRA, EASA, required 4Ib bird strike on the wing of
aircraft, and after this bird strike, aircraft is able to be safely
landed. This study aims to investigate the resistance of the wing
against the bird strike and damage analysis of the high-velocity bird
collision on the model wing, inner structure, spar, and ribs. By using
the Coupled Eulerian-Lagrangian (CEL) approach in ABAQUS/Explicit. Our
contribution 1) bird strike on a wing with assembled inner structure by
aluminium and outer skin composed of unidirectional fiber-reinforced
composite material. 2) bird strike on-wing which is similar with the
first test in which the difference is of spar designed layers of
horizontal plates like a comb. 3) bird strike on-wing which is similar
with second model wing difference in this wing put an aluminium leading
edge on the skin leading-edge, final to analyze the damage of bird
impact on the wing, the velocity of bird strike is 200m/s and analyze
the behavior of the bird at this velocity. Resistance behavior of
composite skin After penetration in the wing, analyze the impact on the
spar and stress on the inner structure. Analysis of the kinetic and
internal energy graph and Comparison all of these results and check the
performance, which gives an excellent result at this velocity. based on
these results suggest which inner part is sensitive.
