Abstract

As a successful application of the Velocity Inter ferometry System for Any Reflector (VISAR) to the performance study of a gas gun, in-bore projectile velocity measurements of a 15 mm bore single-stage gas gun with VISAR are presented. For understanding the gas gun operation analytically, a one-dimensional numerical simulation code was developed and the results were compared to that of the experiments. In addition, in order to verify the accuracy of the VISAR measurement, an optical flow visualization of the flow around the launched projectile with holographic interferometry was also carried out.
