Reduction of Photographic Heat-Transfer Rate Data at AEDC

Abstract

The development of the phase-change paint technique has provided access to a wealth of information in the form of photographs of heating rate patterns on wind tunnel test models. However, difficulty is experienced in the transformation of the data from the photographs to model coordinates because of the distortion of the model image caused by oblique camera views. This report documents the unique capabilities recently developed at the AEDC-VKF for transformation of the photographic information into a model axis system and for presentation of the data in machine generated plots.
