Theoretical Evaluation of the Structural Performance of Swedish Fighter Aircraft Windshields Subjected to Bird Impact.

Abstract : High velocity bird impact characteristics were studied theoretically and the critical velocity, windshield deflection, birdraulics and associated phenomena in Swedish fighter aircraft were predicted. The investigation was carried out for the Swedish Air Force in close cooperation with the Saab Scania Aerospace Co and the results were used to optimize the test program and to propose design improvements for existing crew enclosures.
