Lightweight Composite Launcher Components

The technical objectives of this project are to design, analyze, test, and build a lightweight, corrosion-resistant missile cell and uptake hatch covers to replace the existing metal hatches that are currently used on the MK 41 Vertical Launching System.  Under effort, PEI is proposing will modify the Cell and Uptake Hatch design to incorporate a lightweight unique armor concept.  This new armor design is expected to provide a weight savings of approximately 50% as well as increase the insulative properties of the hatch.  Using the novel armor design will give the hatch an Areal Density (AD) of approximately 8.7-8.8 psf.  In addition to the upgrade in armor which will provide significant weight savings, PEI will investigate improvements for the trunnion design.  Currently, corrosion in the trunnion bearings affects timing which impacts availability and necessitates regular rebuilds.  PEI will develop materials and processes that will result in a composite canister with laminate properties that meet or exceed that of the current autoclaved canister.
