Abstract
An energetic plasticizer for double base propellants comprising (1) a mixe of sorbitol tetra-,penta-, and hexa-nitrate (MSN) and (2) a polyolpolynitrate selected from the group consisting of diethyleneglycoldinitrate (DEGDN), triethyleneglycoldinitrate (TEGDN), nitroglycerin (NG) and mixtures thereof. Also included are compound formulations for double base, modified double base, and composite modified double base propellants incorporating the above energetic plasticizer.
Claims18
As energetic plasticizer for solventless double base propellants comprising, based on total energetic plasticizer weight,
- (1) from 40 to 86 weight percent of a sorbitol nitrate mixture comprising, based on total sorbitol nitrate mixture weight,
- (a) from about 10 to about 20 weight percent of sorbitol tetranitrate,
- (b) from about 60 to about 85 weight percent of sorbitol pentanitrate, and
- (c) from about 5 to about 20 weight percent of sorbitol hexanitrate;
- and
- (2) an additional polyolpolynitrate selected from the group consisting of diethyleneglycoldinitrate, triethyleneglycoldinitrate, nitroglycerin, and mixtures thereof;
- wherein the amount of said polyolpolynitrate is from 15 to 60 weight percent if diethyleneglycoldinitrate is selected, from 14 to 60 weight percent if triethyleneglycoldinitrate is selected, from 18 to 50 if nitroglycerin is selected, and from 15 to 60 weight percent if a mixture of the polyolpolynitrates is selected.
