A STUDY OF THE THERMAL CONDUCTANCE OF METALLIC JOINTS.

Abstract

This report presents the results of a study of the thermal conductance of structural joints utilized in aircraft and missiles. The purpose of the study was to determine the range of values for the thermal conductance of typical aircraft and missile structural joints as well as some of the more important factors which influence these values. It is concluded that the conductances may range from 150 to 1300 BTU/HR sq. ft. degrees F for typical skin-rib structure which is exposed to moderate aerodynamic heating. A more precise prediction of the conductance necessitates an experimental program. In addition, the effects of interface pressure and mating surface roughness were established as the most important factors contributing to the joint conductance. (Author)
