Correlation of HMX (Cyclotetramethylenetetranitramine) Particle Characterization Techniques to Propellant Burn Rate

摘要

Present methods of correlating solid propellant burn rate to oxidizer particle parameters solely depend upon the weight median diameters of the particle distribution. With the broad and variable distribution of the oxidizer particle, vastly different particle surface areas may results in variations in propellant burn rates. This study compares the burn rate of solid propellant to weight median diameters, calculated surface areas from size measurements, measured surface areas, and a new surface area distribution dependent solvolysis method. Comparison of the characterization techniques is performed to determine the role of surface area in the burning process, and the best parameter for propellant burn rate correlations.
