EXPLOSIVE TUBULAR BOOSTER Russian patent published in 2003 - IPC

FIELD: mechanical engineering, applicable for projection of solids. SUBSTANCE: the booster has a propellant charge, electric primers, projected body and a metal tube representing a barrel for acceleration of the projected body. The propellant charge is positioned in combustion chambers separated by movable partitions. The electric primers are installed in the propellant charge, and the combustion chambers are connected by an electric circuit. The last combustion chamber serves as a locking mechanism. The quantity of combustion chambers makes up two and more. A through hollow tube is used for the barrel. EFFECT: enhanced mass and volume of the projected body and reduced mass of the propellant charge. 3 cl, 1 dwg
