Improved Windshield and Canopy Protection Development Program

Abstract

The report discusses a program to develop high performance aircraft windshields and canopies capable of sustaining impacts by 4 lb birds at speeds of 500 knots and above. The designs were to interface with existing aircraft and deviate as little as possible from the physical characteristics or reliability of production designs. A multi-task program evaluated not only bird impact resistance but structural and thermal qualities of materials and designs which influenced overall performance. In the first task, basic material and design properties were established and constructions proposed for full-scale thermal and bird impact testing. Thermal tests on complete windshields compared glass-plastic vs. all-plastic configurations, while bird impacts established the effect of impact location, panel design and support structure. Conclusions from the test portion were the basis of construction selected for prototype production.
