摘要

Subscale vented vessels of two sizes were tested at various levels of vent ratio to determine the effects of vent area and scale (vessel size) on pressurization rates for cannon propellants. Two cannon propellants, M26 and M30, were used in the experimental work. Test results were used to predict the performance of a full-scale vessel - Continuous Automated Multi-Base Line (CAMBL) dryer. Analyses of the results show that the CAMBL dryer containing 680 kg of M26 or M30 propellant would produce a burning-only reaction if these propellants were ignited. The CAMBL dryer should, therefore, be classed a 1.3 burning only hazard. The results of the test were subjected to math modeling efforts. The modeling efforts demonstrated that the variables--vent ratio, scale, and pressure exponent--can be used to predict vented vessel performance. General recommendations for performing similar studies, at some future date, were made.
