Naval Weapon Cook-Off Improvement Concepts and Development
Abstract
Cook-off of ordnance due to accidental ship fuel fires has long been a problem. Effort concentrates both on delaying an ordnance reaction long enough for fire fighters to quench the flames and on reducing the severity of a reaction when and if it occurs. The purpose of the report is to concisely inform the Aerothermochemistry Div. NAVWPNCEN of the major developments (along with accompanying stumbling blocks) directed towards a solution for cook-off; and in so doing, provide the division with a flavor for the experimental techniques and analyses. In part 2 sections are presented in order of increased complexity of concept and computer modeling solvability. In Section A, the early stages of a computer model that simulates cook-off conditions are discussed. In this one- dimensional model, all components, except the explosive, are considered inert. Next, chemically reactive insulative external coatings used to delay reactions times are discussed. Adaptability to a model similar to that in Section A has already been accomplished. Application techniques that will eliminate direct heat paths plus methods that correct the resulting char's erosive and splitting properties are being investigated.
