A Precision Launch Technique for Insensitive Munitions Fragment Impact Testing

Abstract

A precision launch system for conducting Fragment Impact testing as defined in MIL-STD-2105B was designed and developed at the University of Denver, Denver Research Institute (DRI) as an alternative to the FRAGMAT explosive launcher. DRI and National Technical Systems (NTS) are collaborating to use this precision system to conduct Fragment Impact tests against component and All-Up-Round (AUR) munitions at NTS's Arkansas test facility. This specialized launch system has the ability to precisely target and impact shielded and highly sensitive S&A and fuzing train components to enhance reliable determination of reaction origins. The technique utilizes high velocity 40 mm powder guns to deliver two 0.5-inch (12.7 mm) cubical fragments at 8300 300 ft/s (2530 +/- 91 m/s). The primary advantages of this system as compared to the FRAGMAT explosive launcher are, (1) drastically improved impact control and consistency and (2), reduced parasitic overpressure and test area damage which often obscures and confuses test article reaction.
