Abstract:

Significant structural design information on bird-impact resistant windshields was extracted from all available reports of test programs conducted on transport category aircraft since l956. This information was compiled and analyzed for use as a supplement to test and design data contained in CAA Technical Development Reports Nos. 74 and l05. New state-of-the-art developments were emphasized and the validity of previously developed design principles was confirmed. The study revealed that the glassvinyl-glass type windshield continues to be the most utilized design for bird-impact resistance. New developments include the substitution of corrosion-resistant steel for aluminum in the edge design for glass-vinyl panels, the use of an acrylic-vinyl-acrylic laminate in one new aircraft forward windshield, and the incorporation of an acryliccastable interlayer-acrylic laminate in one skylight window design.
