Distribution of Temperatures over an Airplane Wing with Reference to the Phenomena of Ice Formation
This is a 1938 NACA technical memorandum, a government aeronautical research report on temperature distribution over an airplane wing and how ice forms on it, issued for engineers and researchers. The page shows three photographs of test apparatus: a pressure and temperature tap on a model, a model mounted in a wind tunnel, and a wing mounted for testing in a tunnel. For a designer, the images offer grainy, high-contrast views of industrial laboratory equipment, with long receding tunnel walls and bare instrumentation.
