Rupture Pressure Measurements in Modified M392 Rounds

摘要

Reduction of the vulnerability of the ammunition storage compartment for a tank is of current concern to the United States Army. The pressure at which cartridge cases containing propellant rupture is required as input for mathematical models used to design and evaluate new concepts in ammunition box design. A limited experimental investigation was conducted to determine what effects initial case volume and increased initial grain surface area have on the rupture pressure for typical metal cartridge cases used in tank ammunition. Detailed pressure-time curves are presented for each of five tests. Case rupture pressure varied from a low of 30 MPa to a high of 100 MPa. (Author)
