Abstract : The purpose of this investigation was to provide a more advanced radiant heat source capable of heating an area of 1 sq cm with up to 15 cal/sq. cm - sec of radiant heat flux with a uniformity of plus or minus 1 percent. The source and the optical imaging system were to provide a high degree of stability and reproducibility for extended periods. The imaging system is to be used in a study of the effects of intense thermal-radiation on living tissues being carried out at the U.S. Naval Air Development Center in Johnsville, Pa. The specified radiant heat flux and uniformity has been achieved by using a resistance heated graphite element, 16 mm wide and 38 mm long, as the radiation source in conjunction with a compound thermal imaging system. A heat flux-redistributor installed external to the system provided the desired flux uniformity. An operation manual for the source and imaging system is included as an Appendix to the report.
