A visual technique for determining qualitative aerodynamic heating rates on complex configurations /

"An experimental investigation was conducted at a test-section Mach number of 4.95 and a stagnation temperature of 400 degrees F to evaluate a visual technique for obtaining qualitative aerodynamic heat-transfer data on complex configurations. This technique utilized a temperature-sensitive paint which exhibited the characteristic that a pronounced color change occurred at a known temperature. The visual results obtained with the temperature-sensitive paint indicated that this technique was satisfactory for determining qualitative heat-transfer rates on various bodies, some of which exhibited complex flow patterns. The results obtained have been found useful to guide the instrumentation of quantitative heat-transfer models, to supplement quantitative heat-transfer measurements, and to make preliminary heat-transfer studies for new configurations."p.[1]."Langley Research Center, Langley Field, Va."Cover title."October 1960."--Cover.Includes bibliographical references."An experimental investigation was conducted at a test-section Mach number of 4.95 and a stagnation temperature of 400 degrees F to evaluate a visual technique for obtaining qualitative aerodynamic heat-transfer data on complex configurations.
