Abstract:

An experimental investigation of the effects of various thermal and environmental conditions, such as sunlight, rain, wind, and internal heating resulting from firing, on the accuracy of tank cannons is undertaken. The approach taken in this report, is to shroud the tank cannon, thereby negating the environmental effects. The shrouds consist of high-strength filaments S- glass embedded into a low thermally conductive matrix epoxy and in some cases aluminum sheets are also embedded in the matrix. This study ascertains the usefulness of a composite shroud in negating the effects of solar radiation, internal heating and rain. Through the use of thermal shrouds, reduction in muzzle temperature gradients of 83 solar radiation, 11 internal heating, and 90 solar radiation and rain were achieved. This study also reviews all of the past work, experimental and theoretical, and testing that has taken place to date.
