Abstract:

Additive manufacturing provides an opportunity to realize gun tube designs that are not normally considered. Optimization techniques to determine the possible advantages of finned gun tubes over existing tube designs were examined. Two methods were implemented to explore the effect of gun tube geometry on thermal and mechanical performance. One method used a boundary integral approach. The other used a parametric fin design with a finite element method. It is shown that the long-term maximum temperature in a barrel can be reduced by the addition of fins. However, without increased external convection, this advantage is of minimal consequence as the overall temperature rise is still unacceptable.
