Abstract
A propellent charge powder for barrel-type weapons having a plasticizer on the basis of nitramine and nitrocellulose, nitramine and energetic and non-energetic plastic binders, or nitrocellulose or an explosive, and wherein the plasticizer is a mixture of at least two chemically different dinitro diaza compounds. The plasticizer facilitates the production and use of the propellent charge powder possessing a low temperature coefficient.
Claims11
A gun propellant composition comprising:
- an explosive charge powder;
- and
- 2-55%, by weight, based on the total weight of said gun propellant composition, of a liquid plasticizer comprising a mixture of at least two chemically different dinitro diaza hydrocarbons selected from the group consisting of dinitro diaza alkanes, dinitro diaza alkenes, dinitro diaza alkynes and mixtures thereof, wherein said gun propellant composition has a low temperature coefficient in the range of −50° to 70° C.
A gun propellant composition comprising:
- an explosive charge powder wherein said explosive charge powder is selected from the group consisting of solid nitramine and nitrocellulose;
- solid nitramine and an energetic or non-energetic plastic binder;
- nitrocellulose;
- and other explosives besides a solid nitramine;
- and
- 2-55%, by weight, based on the total weight of said gun propellant composition, of a liquid plasticizer comprising a mixture of at least two chemically different dinitro diaza hydrocarbons selected from the group consisting of dinitro diaza alkanes, dinitro diaza alkenes, dinitro diaza alkynes and mixtures thereof, wherein said gun propellant composition has a low temperature coefficient in the range of −50° to 70° C.
