Evaluation of Scratch- and Spall-Resistant Windshields
Abstract
A program was conducted to develop and assess materials configurations offering a potential improvement to the scratching and spalling problems present in existing Army helicopter windshields. Two prototype designs were fabricated for the UH-1 helicopter, flight tested at Ft. Rucker Alabama, and subjected to ballistic and bird impact tests while under flight-simulated conditions. The designs tested included an acrylic windshield (used as the standard), a monolithic polycarbonate windshield with an abrasion-resistant coating on both surfaces, and a glass-plastic composite using Chemcor and polycarbonate materials.
