Abstract:

A theoretical method is presented for determining a spectral and spatial description of the infrared radiation from aerodynamically heated surfaces. The basic laws of infrared emission from opaque surfaces are reviewed and put into a form useful in this application. Heat transfer rates to flat plates and cones in laminar and turbulent supersonic flow are examined and pertinent equations are presented. Solutions for equilibrium temperatures are obtained for representative flight conditions and the radiation laws are applied to produce characteristic radaition patterns at various altitudes and Mach numbers. As an example, the radiation from the skin of a hypothetical aircraft is found for various flight conditions.
