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.
