Abstract
A method for increasing the burn rate of a gas generant formulation is provided involving the addition of a quantity of at least one transition metal complex of diammonium bitetrazole to the gas generant formulation.
Claims25
A method for increasing the burn rate of a gas generant formulation, the method comprising:
- adding a quantity of at least one transition metal complex of diammonium bitetrazole to the gas generant formulation, wherein, after the addition, the at least one transition metal complex of diammonium bitetrazole is present in the gas generant formulation in a relative amount of at least 5 wt. %.
A method for increasing the burn rate of a gas generant formulation, the method comprising:
- adding a quantity of at least one transition metal complex of diammonium bitetrazole to the gas generant formulation, wherein the at least one transition metal complex of diammonium bitetrazole comprises the transition metal copper.
A method for increasing the burn rate of a gas generant formulation, the method comprising:
- including a quantity of at least about 5 composition weight percent of a copper complex of diammonium bitetrazole having an empirical formula of CuC2H6N10 in the gas generant formulation.
A gas generant formulation comprising:
- a primary fuel component selected from the group consisting of copper bis-guanyl urea dinitrate, guanidine nitrate and mixtures thereof;
- a primary oxidizer component selected from the group consisting of ammonium nitrate, basic copper nitrate, copper diammine dinitrate and mixtures of ammonium nitrate and copper diammine dinitrate;
- and
- at least one transition metal complex of diammonium bitetrazole effective to enhance the burn rate of the gas generant formulation as compared to the same gas generant formulation without inclusion of the at least one transition metal complex of diammonium bitetrazole.
