ABSTRACT:
A gun tube thermal shroud for reducing temperature gradients across the gun tube caused by asymmetric external and internal heat flux distributions, which includes an inner layer of high thermal conductivity extending about and along the gun tube in intimate thermal contact with the gun tube. In the preferred embodiment, this inner layer is formed of aluminum wire which is tightly wound about the gun tube and which is embedded in a thermally conductive flexible adhesive. The shroud also includes a middle layer of thermal insulating material and an outer layer of high thermal conductivity material, which may be formed in the same manner as the inner layer.
