Propellant compositions containing cyclic nitramines that are susceptible to unintentional detonation are desensitized by the incorporation of a linear nitramine having a backbone containing one to three ethylene groups and one or two nitramine groups.
1. A low-sensitivity propellant formulation comprising a cyclic nitramine and a linear nitramine, wherein said linear nitramine is a solid energetic material having a melting point within a range of 50° C. to 150° C. and has the formula wherein: m is zero or 1;n is 1 or 2;R1 is a member selected from the group consisting of C1-C6 alkyl, nitrato, azido, nitrato-C1-C6 alkyl, and azido-C1-C6 alkyl; andR2 is a member selected from the group consisting of C1-C6 alkyl, nitrato, azido, nitrato-(C1-C6 alkyl) and azido-(C1-C6 alkyl);such that the total number of...
