Recently IR thermography has been utilized in Japan and Europe in the wind tunnel tests to obtain not only the surface temperatre but also heat flux distribution of the model. The heat flux is deduced from the surface temperature history assuming 1-dimensional semi-infinite conduction of heat. To assure its quantitative capability, there are some issues to be characterized and resolved such as accuracy of the. acquired temperature and the degree of realization of assumed thermal model, etc. Measures and correections for the accuracy enhancement at NAL are discussed.
