Corrosion-Resistant Composite Launch Tube for Out-Board Systems

The developed concept of an advanced hybrid (composite-metal) launch tube for out-board submarine systems addresses feasibility, serviceability, and cost-efficiency of the new hybrid launch tubes which can be used either in conjunction with an existing system or as a stand-alone technical solution that substantially extends service life of the launch tubes (for ten years or more). The performed study proves both the technical merit and cost-efficiency of the new design with regard to a wide spectrum of potential military and civilian applications where a composite/hybrid construction is exposed to extreme loading and/or harsh operational environment. The analytical tool being conceptually developed seems worthy for serviceability characterization of a composite structure undergoing changing force-environment conditions during long-term operation.
