Influence of Propellant Loading Density on Computed Burn Rate in a Mini-Closed Bomb

摘要

An investigation was conducted to determine what loading density should be used to calculate propellant thermochemical properties used in closed- chamber data analysis to minimize the differences in computed burn rates observed as the propellant loading density in the closed chamber varies. A comparison between the traditional loading density of 0.2 g/sq cm and the actual propellant loading density was made. The traditional r = bP(exp n) burn rate law was used as the basis for the comparison.
