Definitions
- the invention relates to a cartridge ammunition, especially medium caliber, and in particular to a training ammunition, with a cartridge case and a projectile inserted into this and mechanically connected to the cartridge case.
- a drive chamber is provided which receives a propellant charge, the z. B. pyrotechnic with the help of a primer is flammable. After lighting the propellant gases of the propellant charge act on the bottom of the projectile, so that after releasing the mechanical connection between the cartridge case and projectile this is expelled from the cartridge case.
- Such cartridgeed training ammunition is described in U.S. Patent No. 5,936,189.
- This cartridge ammunition is used in conjunction with medium-caliber rapid-fire weapons of about 40 mm.
- a plurality of such cartridges are received in a belt, which is then fed to a rapid-fire weapon.
- the drive chamber in the cartridge case is subdivided into a high pressure chamber in which the propellant is received and into a low pressure chamber communicating with the high pressure chamber via transfer ports.
- Cartridge and bullet are mechanical connected via a central screw, which is designed as a predetermined breaking point.
- Such cartridge ammunition is used in high volumes and must be stored both safely and safely transported from the manufacturer to a user. Storage and transport usually take place in larger boxes, z. B. Tin boxes that receive a variety of such cartridges.
- the invention has for its object to provide provisions to avoid a tearing of cartridge case and projectile at a strong increase in the outside temperature on the ignition temperature of the pyrotechnic ignition charge.
- a further object of the invention is to provide provisions to prevent the accumulation of many such cartridges, e.g. B. in a transport or storage container, with excessive increase in the outside temperature, z. B. to avoid damage to the environment by a fire.
- a further object is to weaken the effect of the propellant charge in a danger trap after ignition of the ignition charge to the extent that in the environment neither large pressure damage nor large mechanical damage occur.
- Such a melting material is preferably a molten metal.
- molten metals are z.
- the passages between the propellant and the exterior of the cartridge case can be varied: So z. B. the housing of the primer are made of such a melting material or molten metal; Also around the primer arranged relief holes that are filled with the melt material are possible. Preferably, two or four holes are provided here. Likewise, bores are possible from the drive chamber, starting through the side wall of the cartridge case.
- the passages must be designed so that during the normal firing of the projectiles from the cartridge case, the melt material will withstand the high pressures within the propellant chamber. Compressive strength can be assisted by tapering the passages outwardly as tapered or tapped holes, etc.
- Figure 1 is a longitudinal section through a cartridge ammunition from a projectile and a cartridge case which receives a drive chamber with a propellant charge, wherein between the drive chamber and the outer wall of the cartridge case according to the invention relief holes are provided which receive a molten metal and in this case have a conical shape ;
- Figure 2 shows a second embodiment of a cartridge ammunition with stepped relief holes between the drive chamber and the outer wall of the cartridge case
- Figure 3 shows a third embodiment according to the invention, wherein the housing of a primer for the propellant charge is made of a molten metal.
- a cartridge ammunition 1 shown in Figure 1 consists of a projectile 2 and a cartridge case 3.
- the cartridge case 3 has a drive chamber 4, in which a propellant charge 5 is arranged.
- the wall of the drive chamber 4 is provided with overflow openings 6, which open into a low pressure chamber 7, which is located below the floor 8.
- the drive chamber 4 is provided with a central threaded connector 9, which engages in a central thread 10 in the floor 8. With the floor 8, a flare set 11 is still connected, which dives through the threaded connector 9 into the propellant chamber.
- the cartridge 1 has a caliber of z. B. 40 mm and is also shot down from a pipe weapon, not shown here with swirl, including the projectile here only hinted guide or twist band 12 has.
- the propellant charge 5 is pyrotechnic ignited by a primer 13, wherein the primer 13 is inserted centrally in the bottom of the cartridge case 3.
- channels 14 are provided between the bottom of the drive chamber 4 and the lower bottom of the cartridge case 3, which taper towards the bottom of the cartridge case.
- the channels 14 have z. B. at the bottom of the drive chamber at the caliber of 40 mm, a diameter of 7 mm and taper to about 6 mm.
- B Symmetrical to the center line of the projectile and the primer two channels 14 or three or four channels may be provided, which are located around the primer.
- the channels 14 are filled with a molten metal 15; this molten metal is z.
- the molten metal 15 may, after appropriate heating z. B. poured into the channels 14; or conical rivets are prepared from the molten metal, which then into the channels 14 z. B. be hammered or screwed.
- the driving chamber With the molten metal 15, the driving chamber is sealed tightly and pressure-resistant to the outside, so that the cartridge 1 can be shot down like a conventional cartridge from a gun barrel. Due to the conical design of the channels prevents the molten metal 15 is pressed out of the channels 14 by high pressure in the driving chamber.
- FIG. 2 shows a longitudinal section through a cartridge case 3 and a part of the projectile 2;
- Cartridge sleeve and projectile are the same except for the channels 14 with the molten metal 15, as in Figure 1.
- the channels 14 are stepped holes into which the molten metal 15 is introduced.
- the molten metal poured either in the production of the cartridge into the channels 14 or made out in advance as a rivet and hammered into the channels, or if the channels and the molten metal are provided with a thread, are screwed.
- the relief channels 14, as shown, are located either on both sides of the central primer 13 or in any other arrangement around the primer.
- This cartridge can also be fired like a conventional cartridge; in case of fire or the like the function is the same as described for FIG.
- FIG. 3 shows a further variant of a cartridge, with only the cartridge case 3 and a part of the projectile 2 being shown in FIG.
- the cartridge case 3 is constructed the same in the area of the drive chamber as in the exemplary embodiments according to FIG. 1 and FIG. 2.
- the primer 13 is inserted into a primer housing 14 ', the z. B. is screwed into the bottom of the cartridge case 3 in an insertion opening 14.
- the primer housing 14 ' consists of the mentioned molten metal 15th Climb z.
- the primer housing 14 ' in a fire, the ambient temperature above the melting temperature of the molten metal 15, the primer housing 14 'melts and thus releases a discharge channel corresponding to the insertion opening 14 between the bottom of the drive chamber and the bottom of the cartridge case 3.
- the primer 13 ignites at further increasing temperature and thus ignites the propellant charge 5, it burns only from without pressure can build up, so that the cartridge case and projectile are not torn apart. Pressure damage and major mechanical damage are avoided.
- relief channels 14 always extend from the bottom of the drift chamber to the outer bottom of the cartridge case, it is common for any expert to arrange these channels differently, for. B. through the side wall of the cartridge case and the drive chamber to lead.
