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 NTSs Arkansas test facility. This specialized launch system has the ability to precisely target and impact shielded and highly sensitive SA 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 fts 2530 - 91 ms. 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.
