Snap-Assisted Stackable Hardened Applique Fastener System

To address the U.S. Army need to attach applique armor packages to Combat Vehicle Structures, Physical Optics Corporation (POC) proposes to complete the development of a new Snap-Assisted Stackable Hardened Applique (SASHA) fastener system. SASHA is based on POC's proven, patented line of ruggedized, military connectors, and can be integrated on virtually any structural member (metallic, composite-based, etc.) allowing Army personnel to quickly and easily (un)mount applique armor to/from a vehicle's outer structure during vehicle repair or maintenance operations. This capability directly addresses the PEO Combat Support & Combat Service Support requirements including decreased time for repair (MTTR). In Phase I, POC demonstrated the feasibility of four SASHA design concepts (variants) via finite element analysis and moment loading and blast (shock) testing of four (4) functional SASHA applique fastener prototypes fabricated to support demonstration efforts at TARDEC. POC also developed a relationship with a commercial armor partner to conduct further testing in Phase II. In Phase II, POC plans to fully design, develop, and fabricate two SASHA concepts (variants) and integrate them with deployed armor systems for installation on representative light tactical vehicles. Structural, environmental, and blast testing will be performed to validate the SASHA system at TRL-6.
