Design Modification and Calibration of the Picatinny Activator for Setback Safety Testing of SADARM
Abstract
The relationship between conditions in the Picatinny activator setback testing machine and conditions during an artillery launch of a projectile having a base gap is elucidated through computer simulation of both events. The testing machine simulation is used to prescribe a much improved design for the device, which can then come close to duplicating the launch conditions. The previous design produced overly high pressures and very lengthy pulse durations compared to what is expected during a launch. It also suffered from vibrations which adversely affected repeatability of results. The new design eliminates these problems and can be used to simulate launches even at accelerations high compared to typical artillery launches.
