BURNING CHARACTERISTICS OF STANDARD GUN PROPELLANTS AT LOW TEMPERATURES (21 TO -52 C)

Abstract

The burning characteristics of M-1, M-2, M-6, M-10, M-15, M-17, T-28, T-34, and T-36 propellants were determined in a closed bomb between -52 and +21 C. Burning rates for most of these propellants either decreased 1 to 2%/10 C decrease in temperature or remained essentially constant throughout the temperature range. The apparent burning rate of the M-17 propellant, however, increased abruptly at -21 C. The maximum pressure developed by these propellants at -52 C averaged 7% less than the pressure developed at ambient temperature. Equations for the pressure-burning rate relationship as well as temperature coefficients of burning rate were calculated. The effect of loading density on the maximum pressure is shown to be highly significant, and its effect on burning rate is also discussed.
