Definitions

• the invention relates to a method for operating a weapon system, which comprises both a weapon with a direction in the side and height gun barrel and a Feuerleitrechner and, in the charged state of the weapon, a programmable by the Feuerleitrechner ammunition.
• the ammunition contains a trained as an explosive projectile warhead with programmable detonator, which is fired according to its programming, after firing the ammunition in a, with respect to a moving target, spatially predetermined air blasting point.
• the invention further relates to a weapon system for carrying out this method.
• the height and the distance of the airspray point with respect to the target are selected such that the splinters generated during the detonation of the warhead act optimally on the target.
• the gun of the weapon system may be, for example, the weapons system of a battle tank KPz and the ammunition, for example, the operated in the mode "Luftspreng Vietnamese", used under the name DM 1 1 in the Bundesvid, programmable explosive ammunition (see, for example, the article " The Panzerdetail - Ammunition 120 mm Cannon of RheinmetaH "on the Internet at: http://www.kotsch88.de/m_120_mm.htm (accessed on 19/03/2013)).
• the fire control computer of the fire control system of the respective battle tank usually calculates from the direction of the weapon with respect to the target, the target range, the ammunition-specific ballistic data (firing board) of the propellant charge temperature of the ammunition and the muzzle velocity of the warhead and the warp the battle tank in the area, the elevation and the lateral direction of the barrel and the tempier of the ammunition fighter.
• the transverse wind acting on the warhead is also taken into account.
• the Feuerleitrechner means of appropriate actuators straightening the gun barrel and a transfer of the data (Tempierzeit) on the programmable fuse of the warhead For targets moving toward or away from the weapon at high speed, the known methods are relatively inaccurate, as the target velocity for calculating the flight time of the warhead is ignored.
• a method for operating a weapon system is known from EP 1 452 825 B1, in which the elevation of the weapon barrel and the ignition time of the warhead are determined by means of a calculated muzzle velocity of the warhead of the loaded ammunition for determining an air strike point of the fire control computer.
• the pre-calculation may be performed prior to measuring the actual muzzle velocity. After firing the ammunition, the actual muzzle velocity of the corresponding warhead is then measured and the programmed tempier time of the next warhead to be fired is determined taking into account the measured muzzle velocity.
• the invention has for its object to provide a method of the type mentioned above, with which the optimal air-spot, and thus the tempo of the programmable igniter, can be determined very accurately even if the target moves at high speed to the KPz weapon system or away from it.
• the invention is further intended to disclose a KPz-specific weapon system for carrying out the method.
• the invention is based essentially on the idea that, in addition to the measurements of the target distance, the weft direction, the cross wind and the movement of the weapon, etc., the velocity component of the target (longitudinal velocity L v in) is also determined for the determination of the trajectory and the ignition time of the warhead Viewing direction). For this purpose, at least two temporally successive distance measurements are carried out between the weapon and the moving target and the speed of the target is determined from their difference and from the time interval between the distance measurements.
• the actual distance of the flight time and the measured velocity of the target, the corrected trajectory and the tempier time are determined by extrapolation by the Feuerleitrechner then the gun barrel aligned with respect to its elevation and programmed the detonator with respect to the exact ignition timing of the warhead ,
• the new distance thus results from the current distance plus flight time currently al target longitudinal speed.
• the new flight time is determined from the firing board and the new distance.
• the trajectory and tempier time is recalculated, the tempier time is better calculated for moving (moving) targets.
• a continuous distance measurement is not necessary. Ie. during the straightening process, the distance measurement takes place.
• the longitudinal wind component can, for. B. be queried by a present in the environment or build ble weather station.
• a further increase in accuracy to determine the tempier of the warhead can be achieved in that in addition to the speed of the target and the Speed component of the wind in the direction of the connection axis weapon target measured and then used by the Feuerleitrechner to calculate the elevation of the gun barrel and the ignition timing of the warhead.
• Fig. 1 is a main battle tank, which fires at a fast approaching target once with conventional method and once according to the inventive method.
• Fig. 2 is a schematic view of a weapon system with which the inventive method can be realized.
• Fig. 1 denotes a main battle tank comprising a weapon system 2, which is shown schematically in Fig. 2 as a block diagram.
• the weapon system 2 comprises a weapon 3 with a height adjustable by means of appropriate actuators 4 gun barrel 5 and a Feuerleitrechner 6 with control unit 6 ' .
• a weapon 3 with a height adjustable by means of appropriate actuators 4 gun barrel 5 and a Feuerleitrechner 6 with control unit 6 ' .
• the weapon barrel 5 a by means of the Feuerleitrechners 6 programmable ammunition. 7
• a landing craft to be bombarded which here, for example, in the water at high speed on the example located on a beach main battle tank 1 moves.
• the first trajectory of the warhead 10 assigned to the ammunition 7 is designated by 9 in FIG. 1, as it results when a conventional method is used. Since the speed of the target 8 in the direction of the weapon system 2 is disregarded in this case, the first target distance L 0 determined shortly before the launch by means of a laser range finder 1 1 and the distances of an optimum air-spot point predetermined with respect to the target 8 result. the marked in Fig. 1 with 12 first air blasting point. Due to the rapid movement of the target 8 in the direction of the weapon system 2, the target 8 is in the detonation of the warhead 10 but actually already at a distance L- ⁇ from the weapon system 2, which is so far in front of the first air snap point 12 that the warhead 10 has little or no effect on the target 8.
• the velocity component of the target 8 in the direction of the weapon system 2 is used to determine the elevation of the weapon barrel 5 and the tempier time of the programmable ammunition 7, so that instead of the first trajectory designated 9, a designated 13 (corrected ) second trajectory of the warhead 10 results.
• the second trajectory 13 and the temping time of the detonator of the warhead 10 are chosen such that the optimal second air blasting point 14 is located in front of the approaching target 8 and above it.
• the speed v z of the target 8 moving towards the weapon system 2 is determined from at least two successive distance measurements with the aid of the laser rangefinder 1 1.
• the fire control computer 6 also takes into account the wind speed acting on the target 8 in the calculation of the data for the alignment of the weapon barrel and the tempier time.
• the Feuerleitrechner 6 with a sensor 15 for determining the directed to the weapon 3 wind speed component or a corresponding input option for externally determined wind speeds is connected (Fig. 2). LIST OF REFERENCE NUMBERS
