Curtis, D D

This patent describes a solid propellant comprised on a weight basis of about 15.15% hydroxyl terminated polybutadiene polymer combined with isophorone diisocyanate. About 0.05% carbon black and about 84.8% of a mixture of unground HMX has an average means diameter of about 150 microns and ground HMX, has an average mean diameter of about 8 - 16 microns, wherein the ratio of the ground to unground HMX is from 60:40 to 70:30 by weight and wherein the composite HMX particle size distribution is within various limits.
