DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a directional shaped charge and an ignition tube in an armored armored casing, and a spacer which can be pulled out of the armored armored casing in the flight direction. The present invention relates to an armor-piercing warhead of the type in which the ignition of the directional shaped charge is exploded depending on the inside.

[0002]

2. Description of the Related Art Armor-piercing warheads with extractable spacers are known from German Patent No. 3,727,652. The spacers are withdrawn by the inertial forces generated during firing, with the spacer tips being automatically brought to a forward position as far as possible away from the respective conical directional shaped charge. When the tip of the spacer hits the target, it is directed by a shock sensor (which may be built into the ignition tube and triggered by a shock wave propagating through the spacer) at a defined time interval The shaped charge is ignited. Such shells create relatively narrow and localized holes in very thick concrete walls or armor. When such armor-piercing warheads are fired at relatively thinly armored targets or torches or castles,
The damage effect is relatively small. This is because directional shaped charges are designed to have a large penetration depth and do not act in the width direction.

[0003] Rebound armor has been developed, especially because of the threat of directional shaped charge ammunition. In the case of recoil armor, the outer surface of the object to be protected is equipped with a plate coated with explosives. The firing of the explosives exploded by the shells accelerates the plate, which significantly impedes the formation of a perforated flame beam of directional shaped explosives, so that even objects with relatively thin-walled depolarized armor are directionally shaped. Effective protection against perforated flame beams of explosives is possible. In the case of an object protected in this way, the shell first needs to remove the coating explosive.

[0004] The armor-piercing warhead described in West German Patent 3,804,992 incorporates a pre-directional shaped explosive charge in an extractable spacer and is called a tandem armor-piercing warhead. The pre-directional shaped charge is ignited before the main-directional shaped charge.

[0005]

SUMMARY OF THE INVENTION The present invention provides an armored armor with a directional shaped charge that can be adjusted for passive armor systems, i.e., in a single armored armor with a relatively narrow penetration. Allows the directional shaped charge to be adjusted depending on whether it is intended to produce a significantly higher penetration force or to drill a large hole in a relatively thin armor or structure, if that is the case. In addition, the adjustability is also provided in front of the main directional shaped charge, also for tandem shells having a forward directional shaped charge to explode the explosive in a recoil armor, and in the depth of penetration direction. Is somewhat suppressed so that the hole-expanding effect in the lateral width direction can be strengthened.

[0006]

Means for solving the above-mentioned problems in the armor-piercing warhead of the type described at the outset are:
Partial withdrawal or full withdrawal of the spacer in the armored warhead or retention of the spacer before the directional shaped charge is possible irrespective of the other functions of the armored warhead and when the spacer is in the fully withdrawn or partially withdrawn position It is possible to lock each time.

In a preferred embodiment of the invention, the front explosive, particularly preferably the front-directed shaped explosive, is accommodated in the spacer, and even in the case of such armor-piercing warheads, the spacer is usually Can be fully or partially withdrawn by the shooter (manually immediately prior to firing) or not withdrawn, and can be secured to the armored armored casing in the fully or partially withdrawn position.

[0008]

All known directional shaped charge cartridges with extractable spacers, also called spikes, require expensive and trouble-prone mechanical extraction and control devices. While it was not possible to match the effect (power) of such armor-piercing warheads to the target armor type, in the present invention the artillery gun was optimized for two types of armor each time. It is possible to easily adjust the armored warhead that has to be adapted, so that a single armored warhead can be optimally used depending on the armor type.

In principle, the partial or complete withdrawal of the spacer can be performed “automatically”. That is, when fired in conjunction with a control or delay device, the spacers can be moved by firing, usually by an electric signal, for example by firing a pyrotechnic power element. However, such a device may cause troubles, and the weight is additionally increased and the cost is increased. It is particularly advantageous in the device according to the invention that the adjustment of the spacer is mechanically possible and that the locking of the spacer can be easily carried out manually by the shooter shortly before firing. There is no problem with pulling out the spacer,
It can be released at any time and restored.

In an advantageous embodiment of the invention, besides the (main) directional shaped charge, the explosive body is incorporated inside the spacer as a front charge, particularly preferably as a front directional shaped charge. In the case of such armored warheads with tandem explosives, the penetration capability of the perforated flame beam of the main directional shaped explosive is greater for purely passive armor. In the case of recoil armor, the pre-explosive eliminates the recoil armor, so that the primary directional shaped charge can act on the passive armor without interruption. As described above, according to the present invention, such a tandem-type armor-piercing warhead can quickly and reliably set the protrusion distance of the tip of the spacer from the armor-piercing warhead immediately before firing without danger. It can be used very effectively on armor.

The intentional deterrence of the usual formation of a perforated flame beam of a main directional shaped charge, ie a "late" ignition of a directional shaped charge is necessary and advantageous in the case of less robust armor. is there. Both in the case of an armor-piercing warhead incorporating only a "single" directional shaped explosive and in the case of a tandem armor-piercing warhead, according to the present invention, a directional shaped explosive warhead that acts entirely only in the penetration depth direction Alternatively, a penetrating warhead having a sweeping action that cuts the penetrating site laterally can be obtained.

[0012]

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIGS. 1 to 4 show the creation of a very deep hole in the armor when the ignition takes place at the right time and there is sufficient free space to form a perforated flame beam of a directional shaped charge. A directional shaped explosive piercing warhead that can be used is shown. Insert body 2 in armored warhead casing 3
The directional shaped explosive charge 1 partitioned by the ignition can be ignited by an ignition tube 4 screwed into the bottom. The ignition tube 4
Has a built-in electrical converter, fuze and explosive for generating the ignition voltage. The ignition voltage is generated when the shock wave generated when the spacer tip 5 is in the middle of the target is applied to the tubular spacer 6.
And enters the ignition tube 4 through the armored warhead casing 3. The ignition of the directional shaped charge 1 is known in a different way, for example by means of a sensor integrated in the spacer tip 5 and transmitting the signal of the sensor from the sensor to the ignition tube 4 via a conductive cable. Can also be done. In this case, the spacer 6 is the insert 2
Is designed such that a perforated flame beam of a directional shaped charge can be formed without obstruction in the free space 8 above.

The spacer 6 can be locked at each desired position to the spacer tube guide 7 by, for example, a snap fastening mechanism or a bayonet fastening mechanism. In many cases, the intermediate position of the spacer 6 can be omitted. That is, the tubular spacer 6 is completely drawn out (FIG. 2 or FIG. 4) so that the largest possible space and the longest possible time can be used to form the perforated flame beam of the directional shaped charge, or the spacer 6 is not provided at all. Whether it is not withdrawn (Fig. 1 or 3)
Any position may be selected. In the latter case, the penetration effect is poor, but a "slow" detonation of the directional shaped explosive 1 results in a significantly stronger side effect, and therefore if the armor is not very strong or if it is a wall It is possible to cut out a hole as large as the human body.

FIGS. 3 and 4 show, for example, West German Patent No. 38.
A tandem-type armored warhead having a pre-explosive (in this embodiment, a pre-directional shaped explosive 10) as disclosed in U.S. Pat. It is shown. Predirectional shaped explosive 1
0 is ignited before (main) directional shaped charge 1. FIG.
The armor-piercing warhead shown in Figure 1 has a particularly high penetration force, even with very strong passive armor. In this case, of course, the through-path is only formed relatively thin. Such armor-piercing warheads according to the invention are relatively large in relatively thin armor, even with reaction armor, even if the spacer 6 is pulled out or only partially (FIG. 3). It has a function and effect.

The ignition timing of the pre-explosive and the main explosive is determined according to the requirements of each armored warhead. As can be seen from the above, it is possible, but not necessary, to change the relative ignition times of the pre-directional forming explosive and the main-directional forming explosive when the spacer 6 is pulled out little or no. is not. The firing time interval between bidirectional shaped charges is not critical, especially when an armor-piercing warhead is to be fired in the situation shown in FIG.
