    Device for protecting active armor
    The invention relates to a device for protecting active armor in combat by means of a sensor-guided armor defense projectile with a double hollow charge and a distance sensor using an inflatable hollow body as a disturbing target or masking.
    Modern defense technology has a series of electronic and electro-optical sensors for recognizing and fighting targets. For example, thermal imaging equipment as target interpretation and a sensor-controlled flying body are used as target control. In both applications, the target's own radiation resp. with active, eg radar or laser sensors, the reflected radiation is analyzed, recognized as a target characteristic and used as a control from the flying body to the target. Many attempts have been made to camouflage the target and lead the sensors astray and deflect from the target.
    For example, German Offenlegungsschrift 32 17 977 discloses a device for camouflaging stationary objects against an exploration by thermal imaging equipment, which device is the object to be camouflaged with a stationary geometric structure, heat-sensitive sensors and thermal energy sources, e.g. in the form of a Covered in such a way that the heat-sensitive sensors partially scan the background of the object and simulate the thermal energy sources on the object side facing the enemy thermal imaging device with the same temperature distribution, corresponding to the object background, via a control device. This means that the object can no longer be distinguished from the background.
    German Offenlegungsschrift 33 12 169 shows a jamming object which is ejected from a container in the form of a multi-chambered, inflatable air mattress-like hollow body. This also does not directly protect the armored vehicle, since it throws or rolls, etc. after activation, the jamming target away from the target, in order to deflect the enemy projectile towards the jamming target.
    The purpose of the known devices is therefore to deflect the flying body from the target. However, if this is not successful, these devices do not provide protection against the combat head of the flying body. Such a flying body is generally provided with a hollow charge, which has a rod-shaped, mechanically stable remote detonator. The camouflage device or any, but preferably a short distance in front of the target is pierced thereby, and first the solid surface of the target, e.g. an armor, activates the hollow charge at an optimal distance of about 3 calibers.
    In order to obtain effective protection against this, armored vehicles have recently been equipped with so-called active armor. As a countermeasure, the usual anti-armored missiles are equipped with a double hollow charge, the first of which - a so-called pre-hollow charge - must already be actuated at a very small distance of about 3 to 3.5 m in front of the target, which can only be done with the help of a touchless remote igniter, eg by an LEM. (laser distance measurement) is possible. Protective measures against such projectiles are not known to date.
    The object of the invention is therefore to provide a device with which such remote detonators can be activated prematurely and thus the active armor can be effectively protected against double hollow charges, and the effect remains effective even during longer combat operations, without the dexterity and prevent your own view of the armored vehicle. In addition, the camouflage measures tested so far should also be possible.
    The object is achieved in that according to the invention the object mask-forming inflatable hollow body consists of a composition of separate segments, which are arranged on the total surface of the object to be protected, each segment being inflated from a small house into a "shielding mushroom" - optionally several segments are arranged one behind the other in a disc-like manner with different tempered gas - and in each house from redundancy grounds.
    The invention will be explained in more detail below with reference to an exemplary embodiment and with reference to the drawing. In the drawing: Fig. 1 shows a diagram of an armored vehicle protected by a device; Fig. 2 shows a perspective representation of the device indicated as a masking element; FIG. 3 is a circuit diagram for activating the individual masking elements; Fig. 4 is a block diagram of the control unit and the elements co-operating therewith.
    The armored vehicle 100 shown in Fig. 1 has relatively small boxes 12 on its surface at certain distances and in certain places. In these boxes 12 some preferably a plurality of inflatable, element 11, which expand into an elongated mushroom shape, are arranged. These segments 11 are designed as inflatable hollow bodies and are composed of an elongated stem-like spacer 11b and a wide-face shield portion 11a (Fig. 2). This shield part can preferably be rectangular or square and have a surface of one or more square meters. The spacer 11b, on the other hand, has a stem-like, round, relatively small cross-section, and extends from the armored vehicle over a length of more than 1 to 3 m. The material used is a combination of a highly elastic gum-like film and a tear-resistant, non-elastic , e.g. Kevlar-reinforced foil, in which this foil forms the shield part surface 11c as well as the band-like reinforcements member for the mechanical stabilization of the individual elements 11. The application of the boxes 12 ejecting the individual elements 11 to the armored vehicle 100 is preferably carried out in such a way that the inflated shield parts 11a of all individual elements 11 camouflage the armored vehicle almost without openings and moreover gives a better stabilizing effect.
    In order to achieve the goal of igniting the remote igniter prematurely, i.e. at inoperative distance, it is sufficient to render the shield portion surface 11c opaque and scattering, i.e. reflective, for the radiation of the active remote igniter. This is done by paint coloring (against LEM and other optical sensors) or metallisation (against radar, inductive and capacitive sensors), whereby both measures are coupled in a meaningful way. However, it is advantageous to also camouflage the surface against detection sensors. On the one hand, the device according to the invention thus shields the actively armored target against double hollow charge projectiles, and on the other hand also offers the hitherto known concealment possibilities. The shield portion surface 11c may also be coated, painted, roughened, corrugated, textured or made for special purposes. To stimulate an armor surface, this can be a non-woven metal layer or for further masking of the armored vehicle by roughening, grooves, etc., which return signals corresponding to the running gear, grass, etc.
    Fig. 3 shows an embodiment which, in addition to reliable protection against double hollow charge projectiles, guarantees excellent masking of an armored fighting vehicle. In this case, a foil sector switch 14 with several gas inlet nozzles 14a is added to the boxes 12, in which a plurality of foils are connected layer-wise one behind the other to form the individual segments 11, this foil sector switch 14 being connected over a tube system 13c to a gas generating system 13. . This gas generating system 13 has a hot gas generator 13a, which can also utilize the engine exhaust gases and a cold gas generator 13b. Both are connected directly or mixed via valves 13d, 13d 'and the tube system 13c, by the temperature supply 19a and pressure sensor 14d, controlled supply for the individual elements to be inflated to the foil sector switch 14. Therefore, for additional camouflage against infrared sensors, it is possible to inflate the individual elements 11 in accordance with the environmental requirements, the own temperature or the like requirements with different tempered gas. By inflating the cold gas hollow body 10 disposed in the engine range and in the gas range, thermal imaging devices cannot perform sufficient armor identification, etc.
    The proposed concept also allows the exchange of electro-optical followers by rapid target signature changes, which can be achieved by repeated emptying and refilling of the individual elements 11 with a gas of a different temperature. Target shape and size recognizing sensors, e.g. scanning LEM or image sensors are also interchanged by the significantly changed target peripheral shape and size. If an inflated individual element 11 is damaged or otherwise disturbed by a driving maneuver, which is also noticed by the pressure sensor 14d, among others, the film sector switch immediately switches to the next film of the new separate segment 11.
    The gas controlled by the temperature sensor 19,19a according to the ambient and the fill gas temperature as well as by the pressure sensor 14d of the control unit 15 flows into the gap 12a of the boxes and immediately closes the masking of the armored vehicle 100 again. variants possible.
    In order to fully or partially restore the starting position after the alarm condition has ended, a discharge valve 14b is arranged on the box 12, through which the overpressure in the separate segment 11 can be discharged, so that this suitable elastic material and design are provided, again entirely or partially assumes its starting position. The separate element 11 is also covered by the cap 14c present.
    These measures ensure almost complete mobility of the armored fighting vehicle, even in difficult areas, as well as the adaptability of the protection device to the threat situation.
    Fig. 4 shows an exemplary embodiment of a switching control device. A control unit 15 controls the operation of the individual elements 11 via the valves 13d and 13d 'of the pipe system 13c and the foil sector switch 14. For this purpose it obtains, for example from a laser warning sensor 16 or from vision equipment 17 etc., the required activation signals. This control unit 15 is also provided with a manually operated device 18 and, moreover, one or more temperature sensors 19 and the pressure sensor 14d. Finally, the discharge valve 14b and the sealing device 14c are also operated by the control unit 15.
    This has created a device that protects vehicles with active armor against missiles with double hollow charges and also offers more proven camouflage possibilities, without affecting the mobility of the vehicle.
