Abstract
Abstract The present invention comprises a solid double-base propellant composition containing on a weight basis from about 5 to about 40 per cent of a crystalline substantially non-solvated aluminum hydride, from about 21 to about 33 per cent nitronium perchlorate and from about 30 to about 60 per cent of a plasticized nitrocellulose binder.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
49 words
A SOLID DOUBLE-BASE PROPELLANT COMPOSITION COMPRISING ON A WEIGHT BASIS, A. FROM ABOUT 5 TO ABOUT 40 PERCENT OF A CRYSTALLINE SUBSTANTIALLY NON-SOLVATED ALUMINUM HYDRIDE, B. FROM ABOUT 21 TO ABOUT 33 PERCENT NITRONIUM PERCHLORATE, AND C. FROM ABOUT 30 TO ABOUT 60 PERCENT OF A PLASTICIZED NITROCELLULOSE BINDER.
Claim 2
Dependent Claim
49 words
A SOLID DOUBLE-BASE PROPELLANT COMPOSITION COMPRISING ON A WEIGHT BASIS, A. FROM ABOUT 5 TO ABOUT 40 PERCENT OF A CRYSTALLINE SUBSTANTIALLY NON-SOLVATED ALUMINUM HYDRIDE, B. FROM ABOUT 21 TO ABOUT 33 PERCENT NITRONIUM PERCHLORATE, AND C. FROM ABOUT 30 TO ABOUT 60 PERCENT OF A PLASTICIZED NITROCELLULOSE BINDER.
Claim 3
Dependent Claim
49 words
A solid double-base propellant composition comprising on a weight basis; a. from about 28 to about 38 percent of a crystalline substantially non-solvated aluminum hydride, b. from about 21 to about 33 percent nitronium perchlorate, and c. from about 35 to about 50 percent of a plasticized nitrocellulose binder.
Claim 4
Dependent Claim
49 words
A solid double-base propellant composition comprising on a weight basis; a. from about 28 to about 38 percent of a crystalline substantially non-solvated aluminum hydride, b. from about 21 to about 33 percent nitronium perchlorate, and c. from about 35 to about 50 percent of a plasticized nitrocellulose binder.
Claim 5
Dependent Claim
46 words
The composition as defined in claim 1 wherein the nitronium perchlorate has a surface coating ranging from about 3 to about 10 percent based on the weight of said nitronium perchlorate, said coating being inert to said nitronium perchlorate and the other components of said composition.
Claim 6
Dependent Claim
94 words
A solid double base propellant composition consisting essentially of on a weight basis; a. about 29 percent of a crystalline, substantially non-solvated aluminum hydride, b. about 21 percent nitronium perchlorate, said nitronium perchlorate having a coating of from about 7 to 8 percent, on the weight of said nitronium perchlorate, of a polymeric dichlorostyrene, and c. about 50 percent of a plasticized nitrocellulose binder, said binder consisting of about 25 parts by weight plastisol grade nitrocellulose and 75 parts by weight of a mixture of 15 weight percent diethyleneglycol dinitrate-85 weight percent trimethylolethane trinitrate.
Claim 7
Dependent Claim
94 words
A solid double base propellant composition consisting essentially of on a weight basis; a. about 29 percent of a crystalline, substantially non-solvated aluminum hydride, b. about 21 percent nitronium perchlorate, said nitronium perchlorate having a coating of from about 7 to 8 percent, on the weight of said nitronium perchlorate, of a polymeric dichlorostyrene, and c. about 50 percent of a plasticized nitrocellulose binder, said binder consisting of about 25 parts by weight plastisol grade nitrocellulose and 75 parts by weight of a mixture of 15 weight percent diethyleneglycol dinitrate-85 weight percent trimethylolethane trinitrate.
