Munition Crush Tests in Support of the Navy's High Performance Magazine Program

摘要

The U.S. Navy has currently undertaken a task to improve the design of their land-based ammunition magazines. This effort is part of the Navy High Performance Magazine Program. One of the improvements sought in this task is to prevent ammunition in one cell or bay from being sympathetically detonated by rounds which are detonated in an adjacent bay. One of the means by which this sympathetic detonation can occur is the process of crashing of ammunition by the interior walls of the magazine. The interior walls are propelled into the adjacent bay by the force of the explosion in the bay containing the first initiated ammunition. To determine the conditions under which such a wall can initiate ammunition, ARL has conducted experiments to determine the onset of various types of ammunition reactions when crashed by specially designed moving crush packages and flyer plates. In particular, ARL has conducted experiments to determine the reaction of thin-walled and thick-walled warheads to crushing. By knowing the parameters such as kinetic energy or impulse required to produce certain levels of reaction in ammunition, one can effectively design the internal walls of the magazine and determine the amount of ammunition which can be safely stored in each bay.
