Abstract
A typical spar/skin aircraft structure was heated nonuniformly in a laboratory and the resulting temperatures were measured. The heat transfer function of the NASTRAN computer program was used to provide predictions. The measured and calculated data were compared. Calculated temperatures based on a thermal model with conduction, radiation, and convection features compared closely to measured spar temperatures. Acceptable results were obtained without varying the thermal conductivity, specific heat, or emissivity with temperature since the range of temperature variations was not large. All modes of heat transfer (conduction, radiation, and convection) were shown to significantly affect the magnitude and distribution of structural temperatures.
