Explosive Hazards Tests for Establishing Hazards Classifications for M1 Propellant for Automated Single-Base Finishing Operations
Abstract
Subscale vented vessels of three sizes were tested at various levels of vent areas to determine the effects of vent area and scale (size) on pressurization rates for cannon propellants. Three cannon propellants, M1, M26 and M30 were used in the experimental work; however, only M26 was used to generate data for use in estimating the effects of the above mentioned variables. The overall results were used to predict the pressurization rates resulting from initiation of M26 or M30 propellant in the full-scale AMP dryer. Analyses of the test results and limited mathematical modeling of the pressurization rate in terms of vessel variables indicate that a burning reaction is likely for 680 kg of M26 propellant in this dryer confinement. The properties of M30, relative to M26, indicate that M30 would produce a less severe reaction, under the same conditions as M26 and would, therefore, produce a burning only reaction. Recommendations were made for continuation of the study, using heavy walled test vessels in order for complete reactions to be achieved under the various degrees of confinement. This program would be concerned with M26 and M-30 cannon propellant testing. The final verification of the modeling approach would require testing of the full scale process vessels.
