The invention belongs to a weapon namely to the automatic weapons without ammunition. Particularly it belongs to the weapons using the energy of the explosion mixture gas, flammable liquid or other mixture in the combustion chamber as a mover of bullets. A weapon without ammunition, arranged according to the bullpup scheme, contains: the barrel; the receiver in the form of a cylinder rolling in a rectangular box; the trigger mechanism; the piston for supplying combustible mixture to the combustion chamber and for cooking the compressed air in the mixing tube. This piston is connected by a rod with the piston gas tube; the cylinder full of compressed gas, flammable liquid or other mixture; the drum with several chambers of internal combustion in the form of elongated cylinders. When moving to the trunk a drum is pushed by the nozzle of the lower chamber in the rear part of the bullet and toilet it in the trunk from the top of the camera. This occurs by the rotation around its own axis and longitudinal movement along this axis; the ignition mechanism consisting of a piezoelectric element and the spark; the secondary ignition system consists of a battery and a capacitor; the venting mechanism with the gas tube and piston, in which the gases are directed toward the muzzle; the return mechanism; the multi-function ammunition cartridge of extended capacity, feeding the bullets into the machine vertically. There is a function of the butt, and when you transfer the spare magazines on the body of the soldier there is a function of armor plates.

A case jacket made of a felted, in particular combustible fibrous material, comprising a cylindrical case jacket portion and a calotte-shaped case bottom which is connected to an end of the cylindrical case jacket portion, wherein the bottom-side end of the case jacket portion has a first inside diameter and a first outside diameter, and wherein the case bottom has an annular connecting edge towards the case jacket portion, which has a second inside diameter that is smaller than the first inside diameter, and a second outside diameter which is smaller than the second outside diameter, includes a conical connecting portion whose one end has the first inside diameter and the first outside diameter and is connected to the bottom-side end of the case jacket portion, and whose other end has the second inside diameter and the second outside diameter and is connected to the connecting edge of the case bottom, wherein the angle of inclination of the inner wall and the angle of inclination of the outer wall of the conical connecting portion with respect to the cylinder axis are not more than 10?.

An axisymmetric disk-shaped cartridge is provided for firing from a gun having a fluted bore. The cartridge is initiated by a firing pin and includes a primer core, a propellant charge, a booster charge, a projectile mass, an ablative cap and a ductile metal coating. The projectile mass is disposed over the booster charge while the ablative cap is disposed over the projectile mass. The coating and mass elongate and radially narrow to maintain axial symmetry while being accelerated along the bore.

The invention relates to a charge container device, said charge container device having a volume suitable to substantially fill a barrel chamber, said charge container device is formed from a substantially rigid and combustible material, wherein said charge container device comprises at least one wall to define a cavity for the retention of at least one cartridge case, said at least one cartridge case comprising an energetic material, wherein said at least one cartridge case is arranged in a stacked formation within said charge container, the charge container device further comprising a base portion and a top portion, wherein the top portion comprises an aperture to allow for expulsion of energy and the base portion comprising an ignition means.

The invention relates to a modular charge container device formed of one or more combustible modular cartridges, wherein said combustible modular cartridge comprises two ends, a first end comprising a base portion and a second end comprising a top portion, wherein the combustible modular cartridge is formed using a substantially rigid and combustible material, said combustible modular cartridge comprises at least one wall to define a cavity, wherein the cavity further comprises at least one combustible canister, wherein said combustible canister comprises an energetic material.

A caseless cartridge with a projectile, a propellant, and an ignition source. The ignition source is configured to ignite the propellant in response to an activation of the firearm. The propellant is molded around the projectile and is configured to propel the projectile from the firearm upon ignition. When the firearm is activated, the propellant is consumed, and the projectile and the ignition source are discharged from the firearm. The projectile has a bullet, an ignition housing, and a shaft. The bullet is positioned on a leading end of the projectile, while the ignition housing is positioned on a trailing end opposite the leading end. The shaft extends between the projectile and the ignition housing. The projectile may also have a plurality of fins to stabilize the projectile during flight and a plurality of ignition ports. The ignition source may ignite the propellant through the plurality of ignition ports.

A muzzle loaded ammunition round having a bullet and a consumable cartridge case. The cartridge case is hollow and is filled with at least one propellant composition, the cartridge case being constructed from a consumable material, such as foamed celluloid. The bullet is commonly engaged to the propellant composition at least via the cartridge case, the propellant composition having a charge weight.

A projectile (14) for an ammunition round (10) for use with a small arms or light firearm comprises an elongated projectile body (16). The projectile body (16) has first and second axially opposed ends (18, 20) respectively and a cavity (20) extending there between. The cavity is able to hold a quantity of propellant (24). A plurality of seals (26) extend about an outer surface of the body (16). The seals (26) protrude radially from the body (16) and operate to form a substantial seal against an inner circumferential surface of a barrel (12) of the firearm. Two of the seals (26b and 26c) are mutually adjacent and spaced apart in a direction of a longitudinal axis of the body to form a seal bound outer surface portion (36) of the body (16). One or more holes (38) are formed in the body (16) enabling fluid communication between the cavity (22) and the seal bound outer surface portion (36) of the body (16). This enables pressure equalization inside and outside of the cavity (22) about the seal bound outer surface portion (36) when the projectile (14) is travelling through the barrel (12).

The invention relates to a combustible cartridge case (1) for ammunition, comprising a cylindrical envelope (2) intended to contain a propellant charge and to receive a projectile at a front end (AV). The cartridge case comprises, at a rear end (AR), a bottom (3) that is integral with the cylindrical envelope (2) and is intended to be positioned in a base. The cartridge case is characterised in that the bottom (3) comprises a combustible central ring (5) that is connected to a peripheral cup (4) by at least two combustible radial arms (6) delimiting openings (7).
