A thermal analysis of the M61A1 VULCAN gun barrel was performed. This analysis included the calculation of bore boundary conditions by methods previously developed by the Research Directorate and the application of these boundary conditions to an outer barrel profile analysis. Pressure stress analyses were also performed. The final results are proposed outer barrel profiles for particular performance requirements.
