Claim 1
Independent Claim
36 words
A composite propellant composition comprising (1) an oxidant selected from the group consisting of cyclotetramethylene tetranitramine, cyclotrimethylene trinitramine, ammonium nitrate, 5-aminotetrazole nitrate, ammonium perchlorate and mixtures thereof, (2) triaminoguanidine nitrate, and a compatible synthetic polymer binder.
Claim 2
Dependent Claim
36 words
A composite propellant composition comprising (1) an oxidant selected from the group consisting of cyclotetramethylene tetranitramine, cyclotrimethylene trinitramine, ammonium nitrate, 5-aminotetrazole nitrate, ammonium perchlorate and mixtures thereof, (2) triaminoguanidine nitrate, and a compatible synthetic polymer binder.
Claim 3
Dependent Claim
74 words
The composite propellant composition of claim 1 wherein said oxidant is present in an amount within the range of from about 5 to about 85 percent by weight, said triaminoguandine nitrate is present in an amount within the range of from about 5 to about 70 percent by weight and said binder is present in an amount within the range of from about 5 to about 30 percent by weight of the total composition.
Claim 4
Dependent Claim
