The report is a continuation of a heat-transfer investigation performed as In-House Laboratory Independent Research to determine the effect of interface thermal-resistance on multilayer gun barrel radial temperature distributions. In previous Technical Reports 69-121 and 70-155, published under the same title, the task of establishing the feasibility of induced interface- resistance was discussed. During this reporting period, heat-transfer analysis and experimental correlation were continued. An experimental M60 gun barrel was fabricated and tested. The reduced outside barrel temperatures, of this firing test, demonstrated the effect of interface thermal resistance. Also, a significant effort was directed toward establishing fabrication techniques for a full-length thermal interface barrel.
