Bird Strikes Analysis On Aircraft Wind Shields

Abstract

The purpose of this testing were to determine the effects of bird strike upon the windshield, to determine the best solution to minimize the damage of collision and to study the kinetic energy and momentum during the impact. The pressure can be setting as lowest as 200 psi. This is the limitation of this testing. At 200 psi, all specimens cannot stop the bullet from penetrate. When the penetrations occur, the outbound energy cannot be determined. For the next testing, the machine used must be capable to set the pressure as low as possible. The testing should start from no penetration until penetrations that damage the windshields. The best solution to minimize the damage is by replacing the Perspex to the polycarbonate. The thickness also must be appropriate to absorb the impact collision. Ten millimeter thickness is not able to stop the bullet in the testing. It is highly advised for the next project to increase the thickness of specimens. The kinetic energy and momentum values influence the damage of specimens. The higher the kinetic energy, the more damage occurs. For example, a stork is a large bird with mass nine kilogram. When it collides with an aircraft, the windshield can break and shatter if the thickness is not suitable. In this testing, the Perspex was proved that it could not withstand the impact. The testing can be summarized as a successful testing in achieving the objectives of project. The entire fields in the objectives were covered.
