Definitions
- the invention relates to a practice cartridge with a smaller diameter of the sleeve bottom or end than sharp cartridges,
- the object of the invention is to create a training cartridge which is suitable for training purposes and, in particular, for training a weapon, such as the G36 rifle.
- the cartridge according to the invention is, for example, a 5.56 x 45 brass-plastic training practice cartridge which is suitable for firing from a G36 rifle (NATO standard) with a mass practice breech.
- This practice cartridge ensures precision at a distance of 75 m, with the maximum danger zone being around 400 m.
- the bullet of the cartridge according to the invention has a very short range. This is achieved by an extremely low cross-sectional load, for example by using materials with a lower density of around 1 g / cm 3 , and by a special shape of the projectile, which preferably has a blunt or flattened tip with tear-off edge.
- the bullet Due to the relatively low density, the bullet is susceptible to destruction. Embodiments described in this application which prevent the projectile from being destroyed are therefore of particular interest, particularly in connection with the low density.
- the guide collar with a comparatively large outer diameter is provided in relation to the other diameters of the projectile.
- the sleeve of the cartridge is reinforced in the area of the shoulder, so that it does not deform plastically when fired upon,
- the practice cartridge according to the invention preferably has a low-emission primer, a propellant charge powder, a brass sleeve and a plastic bullet made of petrochemical or biodegradable material.
- the plastic bullet is specially matched to the ballistic external parameters, i. H. takes into account a possible rapid drop in speed.
- the edge diameter of the sleeve base has a diameter of 9.05 mm, which is less than the diameter of 9.60 of a 5.56 x 45 sharp cartridge.
- a custom sharp 5.56 caliber cartridge must not be loadable or functional when using a G36 rifle lock.
- the practice lock only locks with its mass and the closing spring force. The firing of a sharp cartridge would put so much strain on the practice breech and accelerate the firing so much that the weapon housing could break apart and the shooter could also be damaged.
- the configuration of the MPT (brass-plastic training) cartridge together with the special short-track floor and a smaller edge diameter on the bottom or the grip groove of the sleeve, which is preferably made of brass, is a special feature of the present invention.
- the special short-track floor made of plastic is particularly suitable for training purposes,
- the cartridge comprises a projectile with a blunt tip, which is preferably formed by an angle of 1 20 ° and larger. Providing such an obtuse angle facilitates the feeding of the cartridge into the cartridge chamber. This is particularly advantageous when used in fully automatic and semi-automatic weapons. Forming the tip using rounded surfaces further improves the feed of the cartridge into the chamber,
- the projectile has a conical transition section (32) between the guide collar and the crowned or flat tip (31), which can be of a hollow conical shape.
- the hollow cone shape allows weight to be saved as desired.
- the total length of the cartridge case is 43.2 +/- 0.25 mm. This ensures a rapid separation of the projectile and the sleeve in order to counteract the destruction of the projectile.
- the guide collar 36 is then preferably shortened compared to the length that is used in combat ammunition.
- the cartridge can thus be used in standardized calibrations, the guide collar is typically at least 2.5 mm, preferably 3 mm +/- 0.2 mm long, the length of around three millimeters is preferred in order to ensure the transmission of the swirl when fired,
- the diameter of the guide collar is somewhat larger, in particular compared to the standard, in order to ensure the transmission of the swirl when fired and thus the stabilization of the flying projectile. If the diameter of the standard floor is 5.1 mm, the diameter of the floor according to the invention is preferably 5.2 mm.
- the propellant charge shell preferably has a greater material hardness in the front area than a combat cartridge. In particular, this amounts to 165 - 205 hardness drops. This has the effect that the sleeve in the cartridge chamber does not fit completely when firing. This makes it easier to pull out the shot propellant sleeve from the cartridge chamber.
- the projectile has a conical attachment at the rear end, which is typically at least 4 mm long and not longer than 6 mm, particularly preferably not longer than 5 mm.
- the conical extension is 4.5 +/- 0.2 mm long.
- a main body is provided between the conical extension and the guide collar, which is cylindrical in shape and has a smaller diameter than the guide collar. The precision of the projectile is improved
- the main body of the practice cartridge is typically 2.5 to 3.5 mm long, particularly preferably up to 3 mm long.
- the leadership association typically have a diameter greater than 5.75 mm, preferably a diameter of 5.82 +/- 0.02 mm,
- the conical approach preferably includes an angle greater than 10 ° and / or less than 20 °. It is typically 13 ° +/- 1 °.
- a small angle counteracts destruction of the projectile, on the other hand one would have to Small angle means that the projectile mass would be too low and the operating distance would be too short.
- the transition section section (32) is not longer than 5 mm, preferably not longer than 3.5 mm. If the transition section were too long, the material would melt in the barrel of the weapon.
- the projectile material is enriched with barium compound such as barium sulfate. In particular 5-1 0% by weight is contained in the projectile material.
- the projectile can then be detected in the body (human or animal) using X-rays. The material is not toxic. If a human or animal has been accidentally hit by the exercise cartridge, the patient can be helped better.
- FIG. 1 is a side view, partly in longitudinal section, of a first embodiment of the cartridge according to the invention
- Fig. 2 shows a side view, partly in longitudinal section, of a second embodiment of the cartridge according to the invention
- Fig. 3 is a side view of a further enlarged bullet to be inserted into the cartridge sleeve as shown in Fig. 2.
- the practice cartridge I shown in Fig. I has a sleeve 2, preferably made of brass, in the bottom 3 of which a low-emission primer 4 is inserted, which can ignite a propellant charge 6 located in the sleeve 3 through channels 5 arranged in the bottom 3 when the firing pin a weapon, not shown here, from which the practice cartridge is to be fired, strikes the primer 4,
- the disc-shaped end 7 of the sleeve 2 has a reduced diameter compared to live ammunition, so that only this cartridge can be fired in a mass lock specifically designed for training purposes if the weapon has a special mass lock intended for training purposes.
- a neck 9 which is also cylindrically shaped and narrower than the cylindrical sleeve 2, is arranged via a conical shoulder 8.
- a projectile 10 consisting of material of lower density and having an extremely low cross-sectional load, which consists, for example, of petrochemical or biodegradable plastic.
- This bullet has a flattening 11 at the tip or at the front end with a tear-off edge 12, which contributes to the bullet 10 having an unfavorable external ballistic behavior and therefore only having a short range.
- the shoulder 8 of the sleeve 2 is reinforced so that it does not deform when fired at, because the sleeve end 7, which has a reduced diameter, is not adequately held by the weapon’s mass lock used to fire the practice ammunition,
- the sleeve 22 is similar to the practice cartridge 21 or the same as in the practice cartridge 1 according to FIG. 1 trained.
- a low-emission primer 24 is arranged in a corresponding recess, which can ignite a propellant charge 26 located in the sleeve 22 through channels 25 arranged in the bottom 23 when the firing pin of a weapon (not shown here) comes out of the the practice cartridge 21 is to be fired, striking the primer 4.
- the disc-shaped closure 27 of the sleeve 22, which is connected to the sleeve 22 and its base 23 via an extraction groove 33, has a diameter which is reduced compared to live ammunition, so that the practice cartridge 21 can only be loaded and fired when the weapon in question has a special one intended solely for practice purposes Ground lock, which is not shown here.
- the projectile 30 consists, for example, of petrochemical or biodegradable plastic. This projectile 30 has at the outer or front end a low, spherically shaped tip 31 which closes off a conical section 32 of the projectile 30.
- the main body 34 of the projectile 30 is cylindrical and has a conical extension 35 at the inner or rear end.
- the main body 34 is provided with a cylindrical guide collar 36 which is enlarged in diameter and lies in front of the outer end 37 of the neck 29 of the sleeve 22, as shown in FIG. 2.
- the outer diameter of the guide collar 36 is preferably approximately 1.0 to 1.5% larger than the outer diameter of the cylindrical main body 34 of the projectile.
- the conical section 32 forms a transition between the guide collar 36 and the spherical or conical tip 31 of the projectile 30.
- the shoulder 28 of the sleeve 22 is reinforced so that it does not deform when fired at, because the disc-shaped end 27 of the sleeve base, which has a reduced outer diameter, is not adequately held by the rifle lock of the weapon used to fire the practice ammunition.
- the outer diameter of the disk-shaped end 27 of the sleeve 22 is preferably approximately 6% smaller than the outer diameter of the sleeve 22.
