Thermal Loads and Threshold Criteria for Acceptors in the High Performance Magazine
Abstract
The paper presents the results of an analytical and numerical investigation of the High Performance (HP) Magazine for thermal cookoff hazards and mitigation. The HP Magazine consists of an earth-covered box structure enclosing a vehicle accessible shipping and receiving area and two storage wings. Each storage wing is divided by relocatable walls into covered storage cells which can contain up to 30,000 lbs net explosive weight of palletized or containerized munitions. Thermal cookoff threshold models have been developed for three (out of eight) HP Magazine Storage Compatibility Group categories of munitions considered most hazardous with respect to cookoff that could be stored in the magazine (explosives and flammable liquids, bombs, and solid propellant missiles). Gas temperature histories within the magazine have been predicted for fires involving worst case donors. These temperatures were then used to predict subsequent reactions of other munitions stored in storage cells. Total energy release predictions were based on a fire consuming an established amount of energetic material in either the shipping and receiving area or in a storage cell over a 30-minute period. The gas temperature histories were used in conjunction with the munition cookoff models to predict responses. The results indicated that the Bombs category was the most sensitive to thermal hazard. Mitigation techniques were explored to prevent cookoff of the stored munitions.
