Abstract:

Warfighters are in need of precision strike andor small payload type weapons commonly referred to as miniature munitions in order to fill a current gap with respect to surface to surface missiles. Manufacturing of miniature munitions is difficult due to the small size or miniaturization of missile components. Servos, electric motors, electronic boards, metallicnon-metallic components. energetics, etc. can be challenging in order to manufacture prototypes let alone significant quantities required to perform operationaldemonstrational tests. In order to mitigate risk, understand the manufacturing process201es202, and optimize assembly procedures, a virtual prototype modeling tool and methodology is in development for manufacturing and assembly of miniature munitions. Figure 1. is an illustrative example of a process model that depicts the inputsoutputs and the assembly line in a pictorial fashion. Low cost manufacturing, automation processes, and streamlining assembly proceduresmanufacturing cells are targeted in this virtual prototype development. Scenario based planning and predictive analysis can be achieved in order to evaluate critical paths, bottlenecks, and production volumes can be directly derived as outputs from this virtual prototype. In order to reduce cycle times and ensure that product can be quickly and efficiently produced. it is important to analyze the assembly procedures of the individual systems within the overall munitions 201seeker, warhead, rocket motor. servos, etc.202 as well as the munitions as a whole. Process optimization 201manufacturing lineassembly procedures202 can identify processes that are complex or that require significant times which can then be evaluated for cycle time reduction. When drawing conclusions from this modeling tool one should proceed with caution and verify assumptions and constraints. One can imagine that the tool will provide perfect optimization and that the tool rules when it comes to understanding
