An Investigation of the Prevention of Ice on the Airplane Windshield
This 1939 NACA technical report, issued by the National Advisory Committee for Aeronautics and held by the NASA Technical Reports Server, investigates how to keep ice off airplane windshields, written for aeronautical engineers and pilots. Its photographs show windshield and cockpit installations, wiper blades, and a pilot inspecting an iced canopy in the field, giving a designer close, documentary views of early aircraft glazing and mechanical hardware.
