A mathematical model depicting the heat conduction in the rotating band of a projectile and the gun is formulated. A solid inner cylinder in contact with a hollow outer cylinder, both infinitely long, are used to represent the gun tube and the rotating band. The frictional heat flux is imparted to these cylinders at an initial instant and the temperatures in each cylinder are analyzed. The boundary value problem is solved first to generate the eigenfunctions for solving the initial value problem. It is found that the convergence of the temperature solutions are too slow to give accurate data at this time. Further results will be published in the future. Author
