1. A propellant composition, which comprises a particulate organic nitramine propellant and an effective amount for burn rate acceleration of a metal tetrahydridoborohydride of the following formula: Me(BH 4 ) x, wherein Me represents an alkali metal or an alkaline earth metal and x is 1 when Me is
1. A propellant composition, which comprises a particulate organic nitramine propellant and an effective amount for burn rate acceleration of a metal tetrahydridoborohydride of the following formula: Me(BH 4 ) x, wherein Me represents an alkali metal or an alkaline earth metal and x is 1 when Me is an alkali metal and x is 2 when Me is an alkaline earth metal. 2. A propellant composition according to claim 1, wherein the metal tetrahydridoborohydride is present in amount up to about 20% by weight of the nitramine compound. 3. A propellant composition according to claim 1, which additionally contains a binder. 4. A propellant composition according to claim 3, wherein a binder is present in amount up to about 50% by weight of the propellant composition. 5. A propellant composition according to claim 1, wherein the nitramine is at least one of the group consisting of 1,3,5-trinitro-1,3,5-triazacyclohexane and 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane. 6. A propellant composition according to claim 1 or 5, wherein Me is at least one of the group consisting of lithium, sodium, potassium, beryllium, magnesium and calcium. 7. A propellant composition according to claim 1 or 5, wherein Me is sodium or magnesium. 8. A method of increasing the burn rate of a nitramine propellant, which comprises incorporating therewith an effective amount for burn rate acceleration of a metal tetrahydridoborohydride of the formular Me(BH 4 ) x, wherein Me represents an alkali metal or an alkaline earth metal and x is 1 when Me is an alkali metal and x is 2 when Me is an alkaline earth metal. 9. A method according to claim 8, wherein the nitramine is at least one of the group consisting of 1,3,5-trinitro-1,3,5-triazacyclohexane and 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane. 10. A method according to claim 8 or 9, wherein the metal is at least one of the group consisting of lithium, sodium, potassium, beryllium, magnesium and calcium. 11. A method according to claim 8 or 9, wherein Me is sodium or magnesium.
