Definitions

  • the invention relates to a method for operating a weapon system which comprises both a weapon with a weapon barrel that can be adjusted in side and height and a fire control computer and, when the weapon is loaded, ammunition programmable by the fire control computer.
  • the ammunition contains a warhead designed as an explosive projectile with a programmable detonator, which, according to its programming, is ignited after the ammunition has been fired in an air explosion point that can be spatially predetermined in relation to a moving target.
  • the invention also relates to a weapon system for carrying out this method.
  • the height and the distance of the explosive point in relation to the target are selected in such a way that the fragments generated when the warhead detonates have an optimal effect on the target.
  • the weapon of the weapon system can be, for example, the weapon system of a MBT battle tank and the ammunition, for example, the programmable explosive ammunition operated in the "air explosive point” mode and used by the Bundesvid under the designation DM 11 (see, for example, the article " The tank detail - ammunition 120 mm cannon from Rheinmetall "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 in relation to the target, the target range, the ammunition-specific ballistic data (firing board), the propellant charge temperature of the ammunition and the muzzle velocity of the warhead and the tilt of the main battle tank in the field, the elevation and the lateral direction of the gun barrel and the time of the ammunition fuse.
  • the cross wind acting on the warhead is also often taken into account.
  • the fire control computer then activates the corresponding actuators Alignment of the weapon barrel as well as a transfer of the data (Tempierzeit) to the programmable detonator of the warhead.
  • the fire control computer first determines the elevation of the weapon barrel and the ignition time of the warhead by means of a calculated muzzle velocity of the warhead of the loaded ammunition. The pre-calculation can be carried out before measuring the actual muzzle velocity. After the ammunition has been fired, the actual muzzle velocity of the corresponding warhead is then measured and the programming time to be programmed for the next warhead to be fired is determined taking into account the measured muzzle velocity.
  • the U.S. 5,814,755 A describes a method for calculating the dismantling time of a programmable projectile, the calculation being based on at least one impact distance to a target object determined from sensor data, a projectile speed measured at the muzzle of a gun barrel and a predeterminable optimal dismantling distance between a point of impact and a dismantling point of the projectile.
  • the advantage of the proposed method is seen in the fact that a given separation distance is independent of the currently measured projectile velocity.
  • the proposed correction factor for the correction of the dismantling time is based on the shooting elements of the meeting point for the control of the weapon.
  • a device carrying out the method comprises a fire control and a gun, the fire control having a search sensor for the discovery of the target and a follow-up sensor connected to this for target acquisition, 3-D target tracking and 3-D target measurement.
  • a fire control computer is also included.
  • a main filter directs that from the slave sensor received 3-D target data in the form of estimated target data such as position, speed, acceleration, etc. to a lead processing unit.
  • the lead arithmetic unit calculates a hit distance from a lead speed and the (estimated) target data.
  • the lead speed is determined, for example, from the mean value of a number of measured speeds supplied via the data transmission which does not correspond to the currently measured speed.
  • the lead arithmetic unit determines a corresponding gun angle of the azimuth and the elevation.
  • the invention is based on the object of specifying a method of the type mentioned above, with which the optimal air explosion point, and thus the temperature of the programmable detonator, can also be determined very precisely when the target is moving at high speed towards the MBT weapon system or move away from it.
  • the invention is also intended to disclose a MBT-specific weapon system for carrying out the method.
  • the aim is to show a method which can be used for targets at high speed, in particular for movement components of the movement of the target in the direction of fire.
  • the invention is essentially based on the idea of determining the flight path and the ignition time of the warhead, in addition to the measurements of the target distance, the direction of fire, the cross wind and the movement of the weapon, etc., also the speed component of the target directed towards the weapon (longitudinal speed v z in Viewing direction) must be taken into account.
  • the speed component of the target directed towards the weapon longitudinal speed v z in Viewing direction
  • the fire control computer determines the current distance, the flight time and the measured speed of the target, the corrected trajectory and the tempering time by extrapolation, taking into account the target, and then the gun barrel with regard to it Aligned elevation and programmed the detonator with regard to the exact ignition time of the warhead.
  • the new distance thus results from the current distance plus flight time currently as the target longitudinal speed.
  • the new flight time is determined from the shooting board and the new distance. With the extrapolated distance to the target, the trajectory and tempo time are recalculated, the tempo time for moving (moving) targets is better calculated.
  • the method results in an improvement in the accuracy of a MBT in the case of rapidly moving targets, due to the determination of the target longitudinal speed, the consideration of the determined speed and, preferably, the consideration of the longitudinal wind speed.
  • the longitudinal wind component can, for. B. can be queried by an existing or buildable weather station in the area.
  • a further increase in the accuracy of determining the temperature of the warhead can be achieved in that, in addition to the speed of the target, the speed component of the wind in the direction of the connecting axis weapon-target is measured and then used by the fire control computer to calculate the elevation of the weapon barrel and the Ignition time of the warhead is used.
  • Fig. 1 1 denotes a main battle tank, which comprises a weapon system 2, which is shown in Fig. 2 is shown schematically as a block diagram.
  • the weapon system 2 comprises a weapon 3 with a weapon barrel 5 which can be adjusted in height by means of corresponding actuators 4 and a fire control computer 6 with an operating device 6 '.
  • ammunition 7 which can be programmed by means of the fire control computer 6 is located in the weapon barrel 5.
  • a landing craft can be shot at as target 8, which here for example moves in the water at high speed towards the main battle tank 1 located on a beach, for example.
  • Fig. 1 denotes the first trajectory of the warhead 10 assigned to the ammunition 7, 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 not taken into account in this case, the first target distance L 0 determined by means of a laser rangefinder 11 shortly before the firing and the predetermined distances of an optimal air explosion point in relation to the target 8 result in Fig. 1 first air explosion point marked with 12.
  • the speed component of the target 8 in the direction of the weapon system 2 is also used to determine the elevation of the weapon barrel 5 and the tempoing time of the programmable ammunition 7, so that instead of the first trajectory denoted by 9, a trajectory denoted by 13 (corrected ) second trajectory of the warhead 10 results.
  • the second trajectory 13 and the temperature of the detonator of the warhead 10 are selected in such a way that the optimal second air explosion point 14 lies in front of the approaching target 8 and above it.
  • the fire control computer 6 determines the elevation of the weapon barrel 5 and the timing of the detonator of the programmable ammunition and transmits the corresponding data to the actuators 4 and the ammunition 7 before they are fired.
  • the fire control computer 6 also takes into account the wind speed acting on the target 8 when calculating the data for straightening the gun barrel and the temperature control time.
  • the fire control computer 6 is connected to a sensor 15 for determining the wind speed component directed towards the weapon 3 or a corresponding input option for externally determined wind speeds ( Fig. 2 ).
