POWDER CHARGE FOR LIGHT-GAS WEAPONS Russian patent published in 2013 - IPC C06B27/00 C06D5/00 C10L3/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to the field of small arms, namely, to a powder charge for light-gas weapons or firearms. The powder charge comprises gaseous borane and ammonia or borane solution in ammonia and is designed for placement under pressure in a charging powder chamber or a cartridge in the form of a metal or composite balloon, actuation of which is initiated by a source of heat arranged in the breech part of the weapon or on the front end of the cartridge from inside or outside. It is also possible to use catalysts in the form of coal, soot, graphite or methane, and also reaction moderators, such as hydrides, having negative enthalpy of formation, i.e. endothermic reaction of decomposition, for instance, hydrides of beryllium, lithium, aluminium, calcium or their mixture. The source of heat represents a cap, an electric spiral, a spark or an explosive or a cumulative charge arranged inside or outside the cartridge.

EFFECT: invention provides for high initial speed of a projectile, structural simplification of a weapon, increased rate of fire, lower weight of a weapon and cost per shot.
