Abstract : This report discusses the design, analysis, and testing phases of a modification in subscale, kinetic energy projectile technology. Typically, subscale penetrators are posh launched, while the actual full-scale penetrators are traction launched. This condition was acceptable until recently when posh launch technology could no longer fully satisfy the needs of the researcher. Therefore, a technique for implementing traction launch technology into the subscale laboratory environment was needed. This report presents the theory, finite element analysis, and actual testing of one concept. The design process was highlighted by the use of several finite elements codes (implicit and explicit) and the exceptional agreement between the results. (MM)
