Mechanical Analyses Supporting The Design of a Heavy-Walled Tomahawk Concentric Canister Launcher.

Abstract

Structural calculations used to support the design of a heavy-walled Concentric Canister Launcher to withstand a Tomahawk restrained firing are summarized. The loads on the components arise from internal pressure, temperature, and the motor thrust. These loads are used to size components and to predict factors of safety. The test canister is over-designed for the thrust and pressure loads. The largest concern is the thermal loads on the structure. High thermal stresses may cause localized yielding in the lower portion of the uptake. Additionally, localized 'hot spots' not accounted for in one-dimensional fluids calculations have the potential to erode or melt the structure.
