Bullet

The invention relates to a projectile according to the preamble of the patent application Spruchs J, in which often a high dead load portion of an increase in performance sets narrow limits.

The invention is to increase the performance zugr the task; ide> to reduce the dead load share in a projectile of the aforementioned type.

This object is achieved by the invention specified in the characterizing part of claim 1.
SO

The material mentioned in the characterizing part of claim 1 is known from DE-PS 14 28 679, which is a hard core bullet to combat

Tank targets. In doing so, it forms damping intermediate layers low sound hardness and disadvantageously reduces an average Targeted density of the relevant missile.

Advantageously, according to the teachings in the characteristics of the claims 2 to 3 a considerable reduction in the dead load share and thus an increase in performance can be achieved.

According to the teaching in the characterizing part of claim 4 connects with the Reduction of the dead load component, advantageously an improved permeability for electromagnetic radiation.

Furthermore, reference should be made to the advantages that emerge from the teachings the characteristics of claims 5 and 6 result. So can be with one

J5 wing-stabilized full-caliber bullet a very long and light one Design tail girders. This advantageously leads to a more favorable stabilization tilting moment. A tip-side spacer for a wing-stabilized full-caliber bullet also proves itself as advantageous that the material provided according to the invention disturbs a shaped charge spike less than the material customary up to now, for example steel.

Finally, the doctrines appear in the labels of the claims 7 to 9 are beneficial in several ways:

Usually contains a payload projectile, for example to generate fog or the like. at the destination, a predetermined number of containers in a shell. A dead load portion resulting from this is drastically reduced by the invention: it is possible according to the invention to design the projectile casing material itself as a container; each container formed by a hollow sphere is itself part of the load-bearing structure of the projectile casing material. Furthermore, according to the above teachings, a particularly serious problem can be solved:
Some active ingredients prove to be aggressive towards a particular container material, especially if they are stored for a long time, so that they can become an environmentally harmful hazard. You can now

partly not only in numerous small containers »namely the Hollow spheres, but also separated according to components in the latter to store. As long as the individual components are not aggressive per se, there are general advantages in addition to the already obvious advantages significantly improved shelf life.

The teaching in the characterizing part of claim 10 is finally on a. Safe removal of the relevant projectile directed · After Remove the matrix, for example by dissolving, the spherical ones Containers with different properties for reselection. according to different procedures. Examples include: sieving, stream classifying, air sifting, foting, centrifuging, Electrophoresis and magnetic disks. !

JS The invention is illustrated below with reference to the drawing Embodiments of the more detailed explained.

It shows, in longitudinal axial section,
Figure J a wing-stabilized sub-caliber bullet with a sabot,

Figure 2 a twist-stabilized sub-caliber bullet with guide hood and propulsion floor,

Figure 3 is a wing-stabilized full-caliber projectile with a

tip-side spacers for a detonator and a Support for a stabilization tail unit and

FIG. 4 shows a guided missile with a seeker head.

A wing-stabilized lower caliber projectile 10 according to Figure J has a sabot 12 consisting of several, unspecified segments. The segments are essentially made of a composite material manufactured, which has hollow spheres made of glass and / or quartz held together by a matrix, each of which has an individual shell material Phase forms. As a result of the extremely low density of the composite material in question, there is a very low dead load proportion the storey arrangement shown. In an area IJ are

Means for mutual interlocking between the projectile 10 and the Sabot 12 arranged. The form fit is given during the projectile passage in the tube. After leaving the pipe, the Segments from floor 10 and fall to the ground. This proves the low density of the composite material used in addition to an increase in performance of the projectile 10 is also advantageous: the segments only have a very small range and this creates a hazard own troops in the vicinity of the firing position largely excluded. In addition to the weight saving, another benefit is through the extensive replacement of a usually metallic material through the composite material in lower costs for material and production and in a saving of higher quality material and a protection its occurrence given.

In the case of a spin-stabilized projectile 14 according to FIG. 2, it is advantageous both a guide hood 16 and a propulsion floor 18 are made entirely or largely from the composite material. the The advantages resulting therefrom have already been described in connection with the exemplary embodiment according to FIG.

A guided missile 32 according to FIG. 3 has a seeker head 34 with a cladding 36 on the tip side. The latter is made of the composite material having hollow glass spheres, which advantageously not has only a low density to reduce the dead load proportion and an increase in performance, but also by a high density It is characterized by permeability to electromagnetic radiation.

A wing-stabilized full-caliber projectile 22 according to Figure 4 has a tip-side spacers 24 for a detonator 26 and a tail unit support 28 for a stabilization tail unit 30. As a result of Very low density of the composite material already described above, the tail unit carrier 28 can be used to achieve a favorable Stabilization tilting moment and at the same time reducing the Train dead load portion for a very long time. A manufacture of the top-side Spacer 24 results in addition to the reduction in the dead load share the further advantage that a formed from a shaped charge insert 25 Sting is significantly less disturbed by the composite material than by metallic material in the previously common designs.

With all bullets with wedges made of the composite material, which not immediately after leaving the pipe from a missile separate, the hollow spheres of the composite material can be designed as an active ingredient container. The active ingredient is released when the Ball shell by impact or the detonation effect of an explosive device Disassembly charge breaks. In this way, a projectile according to Figure 3 in an advantageous manner in addition to the shaped charge and explosive effect Intended purposes. So the active ingredient can either be used for target marking or to support the aforementioned effects, for example may be used due to additional fire, glare or irritation effects.

A projectile according to the invention can be made using the composite material also designed primarily or exclusively as a payload carrier be.

The composite material is advantageously used for parts which mainly have to withstand pressure loads. If there are other types of stress, for example train, then the composite material can have fiber reinforcements in the relevant areas. With one storey According to FIG. 1, form-locking means on the sabot side can be found in the area 11 contain reinforcements running transversely to the longitudinal axis of the projectile or made entirely of metallic material to absorb the high shear forces be made, which is enclosed on the outside by the composite material.

For example, thermosetting plastics or thermoplastics are used as the matrix material into consideration, in order to achieve a particularly low density of the composite material, the interstices between anainandei'st butt ends Hollow balls can remain largely hollow.
