Further Calibration and Reconfiguration of Single-Stage Gas Gun for Impact Studies

In this study, features of a single-stage gas gun at the Adaptive Intelligent Materials & Systems Center are reconfigured to achieve the optimum performance of the system with consistent results. These features include a new barrel and chronograph. Impact/dynamic tests are conducted using a wide range of applied gas pressure and projectiles with varying shapes and weights to investigate the influence of these changes on the impact velocity. A velocity-pressure relation diagram will be obtained, which will be calibrated with a simplified analytical model. This will facilitate testing a range of structures under dynamic conditions by providing suitable pressures.
