Abstract

ABSTRACT
The high-explosive device has a rear hollow charge 12 with a liner 14 and, axially separated from and ahead of this, a charge with a flat insert 20 that forms a projectile. On approaching a target that is to be engaged, the charges 18 and 12 are initiated in sequence, so that the projectile formed from the insert 20 is effective at the target ahead of the jet that is formed by the liner 14.

Description

~3~
1 26130-~7 The present invention relates to a hiqh-explosive munition device for the engagementr in particular the active engagement, of armoured targets.
DE-OS 34 16 787 discloses such a high-explosive devi~e incorporating ~wo charges, arranged in tandem and inltiated by means provided for this purpose, kinetic energy being generated at the target from the first charge, in order to render harmless an interference system at the target, so that subsequently a hollow-charge jet from the second charge can be unrestrictedly effective at the target. The two charges are essentially of the same diameter, and each of them is arranged in its own housing with stabilizlng fins. After initiation of a separation charge, each forms an indepeadent projectile.
This known arrangement is not only complicated and extremely costly from the point of view of space and production;
it also entails a large amount of dead weight that has no effect at the target. These disadvantages come into play in operations of all kinds such that it becomes a matter of urgency to create a device of this type, which includes very little dead welght and takes up only a small amount of space.
The present invention provides an active munition element for combatting a target provided with a jamming devlce, the munition element comprising: a shaped front chaxge element includlng a front insert and a front charge behlnd said front insert; a shaped rear charge element including a rear inser~
mounted behind said front charge and a rear charge behind said rear insert; means, including a proximity fuze for igniting said front charge, connected for actuating said front charge at a given .

distance ahead of the target in order to develop kinetic energy in the taryet so as to neutralize the jamming device; means for actuating said rear charge after actuation of said front charge with a given time delay so as to be effective against the target without interference from ~ha jamming device; and a tube means deflning a narrow longitudinal channel having a smaller diameter than, and coaxial with, said rear charge element, said channel extending forwardly from said rear insert so as to direct said rear insert therethrough upon actuation of said rear charge, said channel having a front end region housing said front charge.
The invention wlll further be descrlbed in yreater detail below, and by way of example only, on the bas.ls of the drawings appended hereto, wherein:-Figure 1 is a simplified illustration of the principles of the high-explosive munition element according ~o the present invention, shown in longitudinal sertion;
Figure 2 shows a warhead that can be ejected from a payload projectile and that can be guided, incorporating the high-explosive device of ~igure 1;
Figure 3 is a prospective view of an aimable antitank missile with the hi~h-explosive device of Figure 1;
Figure 4 shows a fin-stabilized full-calibre antitank projectile.
In Figures 2r 3, and 4, for purposes of greater clari~y, detailed representation of the structure shown in Fiyure 1 has been omitted.
As can be seen from Figure 1, a munition element or projectile 10 has a casing 11 that is rationally symmetrical about .

the longitudinal axis A, and contains a charge 12. A connector piece 13 serves to accommodate the systems 22 for supplying power to the control electronics 24. A tube 15 defines a channel 16, coaxial with A, for a shaped-charge jet that is to be formed from a liner or insert 14 once the charge 12 has been initiated. In the front area of the channel 16 the tube 15 serves to accommodate a charge 18 with a casing 19 and a flat insert 20 that forms a projectile.
The munition element or projectile 10 is particularly well-suited for the engagement, in particular the active engagement, of armoured targets. A proximity ~uze, not shown hereln and known in and of itself, sends a signal to tbe control electronics 24 when at a set distance from the target. A first control signal to initiate the forward charge 18 is formed from this signal, and the flat insert projectile 20 precedes the main projectile to the target. At the target, the impact of this first projectile 20 causes the interference system or jamming means to be activated and thus neutralized for the hollow-charge jet that i5 formed from the insert 14 of the rear charge 12 that is initiated by a second control signal. The "interference suppression" effect at the target is thus achieved by means that take up very li~tle space, with very little dead-weight, and without the complicated separation charge that renclars the projectile vulnerable to jamming, as is known from the cited publicat1On.
The flat insert 20 of the front charge lB consists preferably of a material having an averaga density of between approximately 16 and approximately 19 g~am3. This means ~ha~

,, ~ ' :L3~3)3~3~i be rendered innocuous so that the hollow charge jet from the insert 14 can be totally effective at the target. It is also possible to achieve a more effective standoff because of this. 3ecause of the comparitive smallness of the insert 20 the advantage arises that the price of the insert material does not play a very great role, so that, for example, there is no real cost barrier to the use of tantalum.
On examining Figures 2, 3, and 4 in conjunction with the foregoing description it can be seen how versatile the pro-jectile 10 according to the present invention is.
As is shown in Figure 2, the high-explosive device 10 is incorporated in a warhead 40 that can be ejected from a carrier pro~ectile as a controllable submunition unit. In this connection, reference is made to a brochure issued by Allied Bendix Aerospace and the applicant Rheinmetall GmbH that has been published since October 1985. The connector 13' extends as far as a target-seeking head 52, known in and of itself, and serves to accommodate the electronics 44 and a control unit 46 with gas generators 48 and control nozzles 50; the above systems and devices are grouped behind the target-seeking head 52, around the tube 15 with the channel 16 so as to take up very little space. Stabilizing fins 42 can be pivoted in known familiar manner from a space~saving transportation position into the operating position shown in the drawing. The direction of flight of the warhead 40 with the high-explosive device 10 is indicated by the arrow F.
As is shown in Figure 3, the high-explosive device 10, :, ~

`` 13~.~3~
- 5 - 26].3~-47 slightly modified (reference is made to -the configuration of the liner 64), has been integrated into an aimable antitank projectile 60. This comprises a launcher tube 62 on a tripod m~unt 74. The central longitudinal axis (not shown herein) of a known sighting system 66, which incorporates the necessary control electronics) is parallel to the longitudinal axis A. A rocket motor 70 can be initiated through the firing system 68. The launcher tube 68 is so adjusted by means of the mount 74 that its longitudinal axis is trained onto an area in which armoured targets that are to be engaged are anticipated. Once the sighting system 66 has identified such a target, a signal initiates the firing system and this in turn ignites the rocket motor 70. The high-explosive device 10 leaves the tube 62 in the direction indicated by the arrow F after the cover 76 has been blown off, and the stabilizing fins 72 are deployed from their retracted or stowed position as shown in the drawing to their operating position. The operating sequence is described in conjunction with Figure 1.
Figure 4 shows an antitank projectile 80 in the form of a known munition for a cannon. With the exception of conical liner 84 for the rear charge 12, details of the integrated high-explosive device have been omitted. The tube 15 is formed as a standoff tube 82 which, at the front, has a known and thus not further detailed or described proximity fuze a6. A known, fixed stabilizing tail assembly 90 is arranged on the tail shaft 88.
