Resw cartridge and propellant charge

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to ammunition, in particular, to remote electric-shock weapon (RESW) cartridges and propellant charges for them. RESW cartridge comprises a non-current-conductive case with a barrel channel, a shell with a current lead laying and a device for fixing on the target, as well as a propellant charge with an obturator. Barrel channel is made with a blind bottom with a thickness of at least 1.5 of the barreled channel wall thickness in the most thick section place. Inside the barreled channel there is an output of the conductive element from the external surface of the case or the current lead inside the case. Laying of the current lead is made in a solid or a deformable shell with an output and fixing of the current lead end from the laying rear end to the front end of the case. Propellant charge of the RESW cartridge is sensitive to an electric-spark and a thermal initiating pulse. Charge is a mixture of a fuel and an oxidizer. As the fuel the charge comprises dehydrated with partial thermal decomposition of potassium hexacyanoferrate(II), and as the oxidant – potassium perchlorate.

EFFECT: provided is higher efficiency of the ammunition.

FIELD: general-purpose systems with transfer of fluid medium, mainly of gases, by changing its pressure and subsequent transformation into kinetic energy of the projectile.

SUBSTANCE: the device has a body with two cavities, in particular, a cartridge case, barrel and a launching tube. The spaces are separated by a partition with through holes. Positioned in the first space is the source of fluid medium, mainly propellant powder charge that is connected with the device of its ignition. The projectile is installed in the body for movement in the longitudinal axis in the direction from the partition under the action of the fluid medium. In the second space provision is made for an additional transverse partition separating it into two parts with one or more longitudinally oriented through channels, whose diameter is not less than 4 times lower than their length and exceeds the diameter of the holes in the first partition.
