Description

The invention relates to a projectile with a projectile casing, an ogive, a guide band and a projectile casing liner arranged on the outside of the projectile casing, the projectile casing having a shoulder on the circumference above the guide band.

The invention further relates to an artillery ammunition comprising such a projectile.

In the case of artillery ammunition, the detonator and warhead form the projectile. In the case of large-caliber ammunition, the drive is usually carried out separately from the projectile and, in conjunction with preselectable propellant charge levels and increases in the weapon barrel, largely enables any trajectory. There are different forms of propellant charge, but depending on the charge weight, they can always be variably adjusted to the required flight path. The storeys themselves can be designed differently and can perform different tasks accordingly. With regard to these tasks, the projectiles can be divided into explosive, explosive, practice, light, and fog projectiles, for example. A division is also based on their basic functionality in storeys with and without emissions.

Projectiles without ejection, for example, conventional explosive projectiles, in which the shell of the projectile is disassembled in the target area using a detonator and the shell produces detonation of an inserted explosive charge into effective ballistic fragments. A cutting floor with a marker load, for example, reveals the DE 3919314 A1 ,

In contrast, projectiles with ejection, often also referred to as cargo projectiles, have a carrier shell and an inserted ejection system, by means of which one or more secondary units are ejected in the target area. The effect of the secondary unit is often adjusted via a delay element only after the ejection. Well-known representatives are, for example, illuminated and fog bullets, such as in the DE 10 2007 057 184 A1 disclosed.

As practice ammunition, there are solutions that aim to recreate the signature of a regular explosive bullet for the purpose of training military forces, for example with regard to smoke bang and lightning. In the DE 10 2011 010 183 A1 For example, a known internal structure of an explosive projectile with a one-piece shell in a multi-part cargo-shell shell is disclosed.

All of the aforementioned bullets according to the prior art have a bullet shell which is made entirely of metal. Such projectile casings, however, have a relatively large dead weight, so that the payload inside the projectile is relatively low if correspondingly high muzzle velocities are to be achieved.

To avoid this disadvantage, bullets with a complete housing jacket made of high polymer plastic, as in the DE 1 174 213 B shown, suggested. However, the high manufacturing outlay and the low stability of the projectiles due to the plastic jacket have proven to be disadvantageous.

Another known approach to setting the weight and center of gravity of a large-caliber projectile is to wrap it with a glass fiber wrap. However, it has proven to be disadvantageous here that the wrapping with glass fibers is relatively complex and the manufacturing outlay is relatively high in order to obtain a uniform surface of the shell. In addition, a smaller diameter is usually formed in the area of the glass fiber winding than above and below it. Furthermore, the cost of bullet casings with glass fiber coils is relatively high.

From the CH 598 562 A discloses a projectile with a projectile casing, an ogive and a guide band. The projectile casing has a shoulder on the circumference and a projectile casing liner arranged on an outside of the projectile casing. The projectile casing liner is formed below the guide band. A screwed-on base cap is provided underneath the shell liner. It is disadvantageous that the grenade body and the interior of the grenade body are considerably smaller in relation to the caliber of the weapon barrel and thus the load that can be taken up inside the projectile is also relatively small. In addition, the weight and center of gravity of the projectile cannot be adjusted.

The invention is therefore based on the object of creating a weight and center of gravity projectile which is easier to manufacture in terms of production technology.

This object is solved by the features of claim 1. Advantageous refinements and developments are the subject of the dependent claims.

According to the invention, a projectile is provided with a projectile casing, an ogive and a guide band. The shell of the projectile has a shoulder above the circumference Leader bands. The projectile body comprises an ogive counter sleeve, which is preferably arranged on the outside of the projectile sleeve, and a projectile sleeve liner which is arranged on an outside of the projectile sleeve and which is arranged between the ogive counter sleeve and the shoulder of the projectile sleeve.

In this way, a floor is created which, on the one hand, is easier to manufacture in terms of production technology and, on the other hand, is adjusted for weight and focus. In addition, the provision of the ogive counter sleeve and the bullet liner creates a bullet that is lighter than a conventional bullet but has the same good aerodynamic properties. The ogive counter sleeve, like the ogive, is aerodynamically advantageously shaped so that the ogive is extended by the combination of the ogive and the ogive counter sleeve. The ogive counter sleeve can be arranged on the circumference of the shell. Likewise, the projectile casing liner can be arranged on the circumference of the projectile casing. The ogive counter sleeve, the projectile casing liner and the projectile casing can connect to one another in the longitudinal direction of the projectile, so that a continuous and aerodynamically advantageous surface contour is created. The shoulder on the projectile casing creates a stop against which the casing casing liner rests. The other side of the bullet liner lies against the ogive counter sleeve. The projectile can preferably be an artillery projectile, in particular as part of an artillery ammunition.

Furthermore, an artillery ammunition is provided according to the invention, which comprises such a projectile or a projectile according to the further development described below. The projectile can be a light, fog, smoke, bang, lightning, signal, exercise or explosive projectile.

In a further development of the invention, the ogive counter sleeve can extend the ogives. The ogive counter sleeve is preferably aerodynamically shaped, just like the ogive, so that the ogive is extended by the combination of the ogive and the ogive counter sleeve. The ogive counter sleeve can be designed such that the shape of the ogive counter sleeve continues the shape of the ogive. For example, it can be provided that the ogive has a curved area and a cylindrical section. The curved area is designed such that it extends the shape of the ogive. In particular, it can be provided that the curved area of the ogive counter sleeve and the ogives at least partially have a common ogive radius.

The projectile casing liner can preferably consist of a plastic without fibers. This plastic is in particular not a fiber-reinforced plastic and also not a fiber composite plastic. Furthermore, the bullet liner can consist of a fiber-reinforced plastic, in particular PA GF 30. However, metallic materials such as aluminum are possible. Such plastics can be machined well by machining manufacturing processes, such as turning in particular. This enables simple and efficient machining of the projectile with existing machines and tools. This also ensures that the required tolerances can be met. Furthermore, by using such a plastic, a projectile can be created that has an impact-resistant envelope. The projectile therefore has a casing which protects it from damage. In addition, a bullet liner made of a plastic without fibers ensures that the bullet's outer shell has good haptics and that the bullet's handling is improved. In particular, if this is carried out manually, the user will find that such a plastic is easier to grip than was the case with the previous surfaces of the conventional projectiles. In addition, such a projectile can be handled with bare hands, i.e. without gloves, even at cold temperatures of significantly below -30 ° C due to the plastic coating.

The ogive counter sleeve can also be made of plastic. However, metallic materials such as aluminum are possible. consists of a fiber-reinforced plastic, or of aluminum.

It can preferably be provided that the projectile casing liner 8th , as a cylindrical, preferably closed, sleeve, and further preferably not as a winding, in particular not as a glass fiber winding.

Furthermore, the projectile can be designed such that at least one cylindrical section of the projectile casing, the projectile casing liner and at least one cylindrical section of the ogive counter casing have a cylindrical region with a common cylindrical surface contour.

In an embodiment of the invention it can further be provided that the common cylindrical surface contour of the cylindrical region is produced by jointly turning the projectile casing, the projectile casing liner and the ogive counter casing. The fact that it can be produced by joint turning allows the entire outer contour of the cylindrical area to be defined in one production step.

In this way it can be achieved that manufacturing deviations are minimized and a repeatably good quality can be achieved. In addition to the improved quality of the projectile, this can reduce the cost of the projectile.

Furthermore, it can be provided that the total concentricity tolerance of the cylindrical region with respect to a first position, which is located on the cylindrical section of the projectile casing, and a second position, which is located on the cylindrical section of the ogive counter sleeve, at a maximum of 0.25 mm, preferably at a maximum 0.1 mm. The overall tour is according to DIN ISO 1101 - the associated standard for shape and position tolerances - defined.

Furthermore, it can be provided that the ogive is integrally connected to the projectile casing or is part of the projectile casing. This integral connection can be formed in particular by gluing.

In addition, it can be provided in an embodiment that the cylindrical section of the projectile casing is formed between the guide band and the shoulder.

Furthermore, it can be provided that the ogive is detachably connected to the shell.

In an embodiment it can be provided that the bullet casing liner is fixed on the outside of the bullet casing by the ogive counter sleeve. In addition, the projectile casing liner can be shrunk on or glued to the projectile casing.

In a further development of the projectile it can be provided that the ogive counter sleeve is glued to the projectile casing. In addition, the ogive counter sleeve can also be shrunk on or glued to the projectile shell.
