In order to simulate an accidental propellant fire, blocks of aluminized solid rocket propellant, with mass in the range of 2-11 kg, were burned in a full-scale enclosure representative of an ammunition storage room onboard naval vessel. Wall heat flux and temperature, as well as gas pressure and temperature were measured to provide information regarding fire behaviour and thermal response of the structure. Burn characteristics of the propellant block, including shape and geometry, were deduced from visible and infrared images. The role of confinement, interior wall insulation or water spray on fire consequences was also investigated. Simulation results from a global model were compared to some experimental data. Agreement and discrepancies were identified.
