Definitions
- the present invention relates to a device incorporated in an armour arrangement, which device reduces or eliminates the effect from armour-piercing ammunition.
- the armour arrangement can also be integrated in a box and can comprise an outer armour, IRA and ERA modules and main armour.
- Armour protection against armour-piercing ammunition is previously known in various embodiments. It is also known to put together different types of armour arrangement, which can here comprise outer armour which protects against small-bore ammunition and small-sized splinters. In addition, it is known to utilize the said IRA and ERA modules, main armour etc.
- An IRA module can here consist of steel plates with intervening inert material (for example plastics sheet). When an ammunition part strikes or acts against the IRA protection, shock waves are formed in the inert material, which makes the plating rise up next to the impact opening. The IRA module wholly or partially eliminates or arrests the ammunition effect. In the ERA module, the inert material is replaced with explosive substance.
- Various types of armour protection which are disposed in box-like arrangement and can be launched against approaching ammunition can also be found.
- the arrangement must be able to be provided for fixed installations, combat vehicles, etc. and must be able to produce a sensitive and effective means of protection against shelling.
- the invention solves this problem also.
- a device may be deemed principally to be characterized in that it comprises at least two IRA modules arranged at a distance apart viewed in the direction of action of the ammunition part, in which the respective IRA module is provided with separate sub-zones arranged at a distance apart in the direction of extent of the module and situated within one and the same region of extent for the material in question, for example plastics material, of the IRA module, and is assigned or comprises elements, for example crystals, piezoelectric layers, etc., which, in dependence on mechanical vibrations or shock waves in the region of extent, initiate electrical voltage.
- the ammunition-related part or effect which penetrates to the IRA modules and generates the said mechanical vibrations or shock waves causes voltage to be generated in one or more elements, which can be used to initiate, wholly or in part, and/or provoke triggering of one or more ERA modules (counteragents).
- sheet-shaped members are fixed or baked into a plate formed of inert material, which can here be constituted by a plastics plate, which forms part of the respective IRA module.
- the said shock waves or vibrations arise when the ammunition part or ammunition effect in question (for example RSV beam) strikes and possibly penetrates the plate.
- Member(s) running on current or voltage can be designed to react to the voltage generation or the voltage generations in one or more of the said elements. In dependence on the voltage generation in one or more elements under the action of the ammunition part or ammunition effect, the site of the point of penetration in the surface which is exposable to the ammunition effect is pinpointed with relatively great accuracy.
- the member(s) running on voltage and/or current can also be designed to detect the rate of penetration of the ammunition part or ammunition effect in question.
- the said member(s) running on current and/or voltage is/are designed to store generated electrical energy, for example in a capacitor.
- the energy can subsequently be used to produce counter-measures during the shelling, i.e. selection and/or triggering of an ERA module or part of such a module.
- An armour arrangement can be characterized in that two successive IRA modules are designed, when penetrated by an ammunition part or ammunition effect and in dependence on mechanical vibrations or shock waves, to generate electrical voltage(s) by means of crystals or piezoelectric elements disposed on continuous surfaces on the inert material of the IRA modules.
- Member(s) running on voltage, current and/or energy is/are designed, in dependence on the said voltage generation by the elements on the continuous surfaces, to detect the point of penetration on that surface of the arrangement which is exposed to the weapon action and, in dependence on the detection, to produce or create voltage, current and/or energy for initiation and triggering functions for an incorporated ERA protection.
- the armour arrangement in question can here require, as a security condition for the initiation of the ERA module(s), that the penetrating ammunition part or ammunition effect must have a predetermined velocity value or velocity value range.
- a security condition for the initiation of the ERA module(s) that the penetrating ammunition part or ammunition effect must have a predetermined velocity value or velocity value range.
- triggering condition can be included the rapidity of the voltage build-up in the respective crystal or piezoelectric layers and/or the requirement that the voltage level must have a predetermined value or value range.
- the invention enables the ERA part to be orientated and configured within wide frameworks.
- a new function, as well as structure and orientation, can be assigned to the IRA modules within broad frameworks.
- the IRA modules can detect various ammunition velocities. When the ammunition unit has struck a building, tree, natural object etc. and has therefore acquired low velocity at the point of impact, the ERA protection does not need to be triggered, which case can therefore be separated off by the new device. Likewise, the ERA protection must immediately be triggered in the event of velocities above a certain value, which can also be enabled with the new device.
- the generation of voltage or electricity can possibly be coordinated with an internal battery source and/or an external energy connection.
- the site of impact can be effectively located on the possible total impact surface, which increases the effectiveness of the counteragent since this can be aligned and nominated and thereby optimized.
- an armour arrangement is fundamentally represented by 1.
- the arrangement includes an outer armour 2, which protects against small-bore ammunition, small-sized splinters and the like. Should something penetrate the outer armour layer 2, for example a bolt or RSV beam, the velocity of the penetrating ammunition part or ammunition effect is measured in a unit 3, formed by two IRA modules 3a, 3b, which are known per se.
- the IRA modules 3a, 3b are followed by an ERA module 4, which in turn is followed by a main armour 5.
- the arrangement can be disposed on a fixed installation or on combat vehicles and can, per se, be enclosed in a box 6 or other enclosure arrangement.
- An approaching ammunition unit is denoted by 7 and the direction of approach by 8.
- the modules 3a, 3b are arranged one behind the other.
- the arrangement parts 2, 3, 4 and 5 can be constituted by a type which is known per se and which shall not therefore be further described here.
- the modules 3a, 3b can consist of steel sheets with a plate, for example a plastics material plate, of inert material in between. In the ERA module, the plate is replaced with explosive material.
- FIG. 2 shows parts of the IRA modules 3', 3" in more detail.
- the two IRA modules each comprise a plate 9 and 10, which, according to the above, can here be constituted by plastics plates of a material which is known per se.
- the IRA modules are mutually arranged such that the plastics plates remain arranged substantially parallel to each other.
- the respective plate bears sheet-shaped layers 11, 12 and 13, 14 on both its sides.
- the layers are provided with mutually separate zones (sub-zones), two of which are denoted by 15 and 16.
- sub-zones mutually separate zones
- elements 17 of the type which generate electrical voltage in dependence on mechanical vibrations or shock waves which arise in the respective plate as a result of the action of the ammunition part or ammunition effect (RSV beam) upon the plate.
- the said elements can consist of crystals or piezoelectric layers of a type which is known per se.
- FIG 3 for the sake of clarity, only the plastics plates of the IRA modules, with associated foils, are shown.
- a distance A is indicated between the parallel-arranged plates 9', 10'.
- the time between the penetration of the ammunition part 7' into the first plate 9' and the second plate 10' in the direction of approach 8' can be measured with electrical detection members 18 and 19, indicated only in basic representation.
- the detection members are connected to the elements 17' on the sheet-shaped members 11', 12' and 13', 14' of the first and second plates 9' and 10'.
- the elements are connected to the said detection members 18, 19 by electrical connections, for example electric wires, two of which are denoted by 20 and 21.
- the ammunition unit 7' first strikes the plate 9' (i.e.
- the IRA part 3b in Figure 1 acts upon the voltage-generating elements of this plate, which voltage is registered by the detection members.
- the ammunition part strikes the second plate 10' (the IRA module 3a) and thereby generates voltage in the elements of this plate.
- the time difference between the penetration of the ammunition unit into the two plates can be measured and thus, for example, the velocity of the penetrating object or the ammunition part 7' can be measured or calculated.
- This calculation can be performed in a unit 22 which is connected to the units 18 and 19. In dependence on the detection and the calculation, the unit 22 can produce an outgoing aiming or triggering signal i1 to another part of the armour arrangement, for example to the ERA module 4.
- the penetrating ammunition part 7" is shown from the rear.
- the penetration causes shock waves or vibrations 23 to propagate in the material of the plate 9".
- the shock waves act upon the elements in dependence on how close these are to the point of penetration 24 in question.
- a unit 25 is used, which detects the effects or the voltage generations from the elements 17''.
- the unit 25 can here have electrical components in the form of a resistor 26, an energy-storing member (capacitor) 27, etc.
- the unit 25 can in this case store energy which has been generated by the penetration and can produce an outgoing signal i2 for the aiming and triggering of a counteragent (ERA module) in the armour protection.
- the members which run on voltage, current and/or energy, as well as the signal-processing members, can be constituted by circuits which are known per se and shall not therefore be further described here.
- the circuits 18, 19, 22 and 25 it is possible to measure the speed difference with which the crystal voltage is generated in the various crystals and in this way to position each exactly on the protection or the total protective surface 28 at which the penetration occurs, i.e. the site 24, so that the possibility is given of choosing a suitable initiation point in the ERA part, which can here be of the type having a plurality of initiation points.
- a security condition for the triggering of the ERA part can be used, inter alia, the velocity of the ammunition part 7' or equivalent and, for example, the requirement that this velocity must exceed a certain value.
- Another condition can be to indicate, for example with the aid of the unit 25, the speed with which the crystal voltage level is built up, and/or the requirement that the built-up crystal voltage must reach a certain level.
- the elements 17 can have any chosen shape (round, hexagonal, etc.).
- the box 6 according to Figure 1 can include a battery source B and/or an external energy supply Y.
