摘要:
An encapsulated propellant charge comprised a sealed combustible container comprised of a consumable material and having a substantially cylindrical shape. The sealed combustible container comprises a top wall, a bottom wall, and a side wall therebetween. The top wall, the bottom wall and the side wall define a chamber; which contains a propellant composition.

The invention relates to a personal weapon, intended for semi-automatic and automatic firing of caseless ammunitions, provided with an electronic fire controller with biometric identification of the person firing. The weapon has a sealing device for the chamber based on using segments or corollas with variation of bore size mechanically or with gas pressure. A delay in opening the barrel/breech unit may be introduced using spigots driven by propellant gases. A device for sequencing compartments in tandem of the magazine uses the volume reduction of ammunition to double the power of the firearm. A removable locker permits the integral locking of breech unit, trigger, magazine and dismantling bolt for an absolute weapon safety. A telescopic extension device for the barrel increases the power of the ammunition and a gas bleed in the chamber permits the stabilisation of the firing.

According to known techniques for winding an ammunition shell the number of thread layers is often reinforced as compared to the remaining part of the shell wall, especially in those zones of the shell where the load is the highest, thereby, however, inevitably increasing the thickness of the shell wall. If the space for the propelling charge in the wound shell is to be enlarged while the outer geometry of the wound shell remains the same, that is with the same space provided in the weapon for the charge, the wall thickness has to be reduced. In order to provide the shell with the same mechanical stability, despite the reduction in wall thickness, as shells whose wall thickness is not reduced, the wound body of the shell (50) is produced from chemical fibers (53), preferably from synthetic and inorganic chemical fibers.

A process to control resin migration in combustible cartridge cases composed of nitrocellulose fibers and cellulose fibers is provided by adding to the conventional method the step of dipping the already formed and resin impregnated case into a liquid which is miscible with the solvent used to impregnate the resin into the felted cartridge case, but which is a non-solvent for the resin thereby precipitating the resin in situ and subsequently completing the formation of the case by drying.
摘要:
A method for producing a shell and a shell produced by this method, wherein the shell has a projectile, a combustible propellant charge casing, and a casing cover that joins the propellant charge casing with the projectile, such that the projectile has a sealing ring adjacent to the casing cover. To realize cost-effective assembly of a shell of this type, the casing cover is produced as an injection molded part made of an elastic plastic, such that the front end region of the casing cover facing the projectile forms the sealing ring.
