Definitions
- the present invention relates to a training weapon system for a portable recoilless anti-armour weapon of the type which comprises a sub-calibre insert barrel arranged in the bore of the launching barrel of the anti-armour weapon.
- a recoilless anti-armour weapon in which the invention can be used is the 84 mm Carl Gustaf recoilless gun m/48.
- sub-calibre ammunition training weapons it is previously known to use sub-calibre ammunition training weapons .
- the training weapon has a sub-calibre insert barrel arranged inside the barrel of the parent weapon in question.
- sub-calibre insert barrel arranged inside the barrel of the parent weapon in question.
- 9 mm and 20 mm calibre have been developped.
- SE 9400043-7 One example of a 20 mm calibre training weapon of this type is illustrated in SE 9400043-7.
- the 20 mm training system provides a due, realistic sound level around the weapon and this system also provides an out-blow effect because of its recoilless function.
- the sub-calibre barrel is disposed in the bore of the full-calibre weapon in a body shaped as a round of ammunition similar to the full-calibre high explosive shell.
- the sub-calibre barrel is smooth-bored.
- the accuracy of such a system is unsatisfactory as soon as the firing distance exceeds 250 m.
- Recoilless ammunition rounds of this type also have a plastic bottom plate member which is broken when the round is fired.
- the bottom plate member When the bottom plate member is broken it is divided into small splinters which could be dangerous up to 70 m behind the weapon. This can be compared with a required safety distance of 15 m for the service weapon under war conditions.
- the object of this invention is to provide a sub-calibre weapon system for training purposes in which the accuracy and safety has been improved but at reduced cost compared to previous systems of this kind. According to the inven- tion this is achieved by providing the sub-calibre insert barrel with a rifled bore and arranging the insert barrel so that the forward aligning member of the barrel is engaging the ridges of the rifles in the rifled section of the full-calibre weapon.
- the reason for choosing a calibre 20 mm system is the fact that such a system provides a realistic sound level around the weapon, as already mentioned. It also seems as if a calibre around 20 mm has an optimal cost efficiency relative to the required training and feeling experience.
- the sound-level for a 20 mm system is approximately 170 dB to be compared with approximately 180 db for the full-calibre version.
- the duration of the sound wave (A-duration) is approximately 1/3 of the real system and is experienced as fully satisfactory.
- the training weapon comprises an insert barrel 1 for a sub-calibre projectile.
- the insert barrel is mounted in a body 2 shaped as an ordinary ammunition round and which is loaded in the gun in the same manner as the ordinary full- calibre round.
- the body 2 has a conventional, elongated cylindrical portion 3 and a conical forward portion 4 and a calibre of 84 mm.
- the insert barrel 1 is mounted in the body 2 by means of a forward aligning member 5 for centering the barrel and a rear breech block 6 with an ignition channel 7 and threads 8 for the nozzle screw.
- the rear part of the barrel has a conventional firing chamber 9 for the training projectile.
- the insert barrel 1 has a rifled bore instead of being smooth-bored like previous training weapons of the insert type.
- the retardation of the projec- tile in each point of the trajectory should be as similar to the corresponding live projectile as possible. This is achieved if the ratio of the projectile mass to the air resistance area is the same for the two types of ammunition units. Consequently, a spin stabilized projectile can be made with a less projectile mass compared to a corresponding fin stabilized projectile. As a result the amount of powder could be reduced which means a less expensive product.
- the accuracy of a spin stabilized training weapon system is also improved due to the inherent stability in such a system. It is well known that it is very difficult to provide a corresponding accuracy in a fin stabilized system.
- the forward aligning member 5 of the weapon is engaging the ridges of the rifles of the rifled portion in the bore of the gun barrel instead of engaging the conical (not rifled) firing chamber portion of the gun like in other similar training systems .
- the forward aligning member 5 is made as an annular sleeve having a circumferential portion 10 forming the contacting surface against the projecting ridges of the rifles.
- the longitudinal dimension of the contacting surface exceeds the width of a rifle groove so that the aligning member 5 bridges a rifle groove and is contacting the projecting part (ridges) of the rifles only.
- a vent hole 11 is made in the cylindrical wall of the breech block to reduce the pressure on the nozzle screw. Any gas leakage at the rear surface of the cartridge case can then escape through this hole instead of passing through the threads 8, like in other systems. The risk for an unintentional unscrewing of the nozzle screw can then be eliminated.
