Abstract

COST EFFECTIVE, YET OPERATIONALLY RELIABLE MUNITIONS CONTAINER CLOSURE SYSTEMS ARE OF VITAL CONCERN TO THE U.S. AIR FORCE. THE PAHSE I TECHNICAL RESULTS DOCUMENTS SUFFICIENT PROMISE FOR RESOLUTION OF THESE CONCERNS VIA CONTINUED EXTENSIVE PHASE II RESEARCH AND DEVELOPMENT. PRESENTLY, MUNITIONS CONTAINER DESIGN, MANUFACTURE AND EFFECTIVENESS ARE HEAVILY INFLUENCED BY THE TYPE OF CLOSURE SYSTEM USED TO MATE AND SECURE UPPER AND LOWER SECTIONS. THE MOST COMMON SYSTEM EMPLOYS THE OVER-CENTER-DRAW BOLT TYPE LATCH, WHICH BY NATURE OF DESIGN (SEE PHASE I SBIR CLOSURE SYSTEMS FINAL REPORT, HEREIN) IS DETRIMENTAL TO OBJECTIVES OF OPTIMUM OPERATIONAL CONFIGURATION. UPPER CONTAINER EXTRUSIONS HAVE CUT-OUTS TO INTERFACE WITH THE LTACH SHAFT AND BARREL-NUT, WHICH ARE COSTLY TO MANUFACTURE AND HIGHLY SUSCEPTIBLE TO FRACTURE. LOWER EXTRUSIONS, ALSO DESIGNED TO ACCOMMODATE THIS LATCH HAVE LIKEWISE EXPENSIVE MANUFACTURING FEATURES AND HIGH DAMAGE POTENTIAL. ONE EXAMPLE, IS THE INDEPENDENT FORKLIFT TYNE ACCESS AND HANDLING SKID, WHICH MUST BE WELDED ONTO THE EXTRUSION. COMBINED, THESE LATCH AND EXTRUSTION CHARACTERISTICS RESULT IN CONTAINERS THAT ARE OVERLY EXPENSIVE TO MANUFACTURE, NOT EASILY REPAIRABLE BY THE USER, AND LESS THAN OPTIMUM IN OPERATIONAL EFFECTIVENESS. OPERATIONAL MOVEMENTS/HANDLING THAT RESULT IN DEFECTIVE LATCHES, "OVER-TORQUED BARREL-NUTS", DAMAGED EXTRUSIONS, AND ULTIMATELY DEGRADATION OF ENCASED MUNITIONS SHELF/SERVICE LIFE.
