Development of a Venting Selection Methodology for Fast and Slow Cook-Off Mitigation
Abstract
Most high explosive warheads respond violently to unplanned cook-off in fires and do not comply with NATO insensitive munitions (IM) test STANAGs. The Program Executive Office for Ammunition (PEO Ammo) developed an IM strategic plan to establish methods for improving the IM characteristics of munitions. A design guide was developed to provide a venting decision methodology to assist Program Managers and systems developers in selecting the best venting concepts for application to their munitions. A structured framework was developed that incorporates customer's requirements and corresponding engineering metrics. The engineering metrics along with their rating were used to rank the effectiveness in achieving various munition requirements. By comparing candidate concept venting scores, one can see which venting concepts offer the greatest value to the customer. Several munition examples were run through the template to select the most appropriate venting approach. Based on the template output, the selected approaches were experimentally evaluated and demonstrated to show improved IM response under slow cook-off conditions resulting in a cost savings over using a standard experimental design approach.
