Overview of Proposed Joint Air Force and Navy Subscale Fast Cook-off Program
Abstract
Department of Defense (DoD) and Department of Transportation (DOT) hazards classifiers as well as propulsion hazards personnel from the military and industry have long recognized the potential hazards of storage and transportation of solid rocket motors. DoD hazard classification guidelines in Technical Bulletin (TB) 700-2, NAVSEAINST 8020.8B, TO 11A-1-47, and DLAR 8220.1 (hereafter referred to as TB 700-2), and 49 CFR 100-180, UN Test Manual, and other related documents address the specifics of testing and classifying materials and articles containing explosives. At the present time, the Department of Defense Explosive Safety Board (DDESB) and Joint Hazard Classifiers (JHC) require compliance with the United Nations (UN) Test Series 6 (c) external fire fast cook-off (FCO) test protocol (or pre-approved test plan) for any solid propellant system that is to be classified into Hazard Divisions 1.1, 1.2, 1.3 and 1.4. The protocol requires that full-scale articles in their shipping containers be subjected to a series of external fire FCO tests and meet the specific requirements as listed in TB700-2 to qualify for a Hazard Division (HD) 1.3 classification. A project is described to identify the critical features needed for a subscale analytical and experimental alternative to the UN Test Series 6 (c) external fire FCO test protocol. The work would include a definition of fire scenarios and characteristics of the fire hazards associated with transportation and storage of large rocket motors. The response of an item to thermal threat would be obtained through the compilation of existing data, in combination with a synergistic analytical and experimental program. A hazards response protocol, which identifies the controlling parameters of fast cook-off, would be generated. Analytical tools would be used to perform a sensitivity analysis on the control to identify their importance.
