Definitions

  • the invention relates to a fire control and navigation system for moving weapon carriers according to the preamble of claim 1, which is particularly suitable for battle tanks but also for other vehicles that are used for targeting and location purposes via a primary stabilized system and also via a secondary stabilized system that is movable relative to the vehicle feature.
  • Modern weapon systems are nowadays required to be able to be used when the weapon carrier is in motion.
  • the movement of the weapon must be known or the weapon must be stabilized in order to compensate for the movements and thus disturbing influences of the wearer, such as other movement and acceleration components acting on the weapon, at the time of the projectile departure.
  • a battle tank with a barrel weapon that can move freely about two axes, that is to say about the vertical axis in the azimuthal direction and about an elevation axis in height, is to be considered.
  • the ballistic trajectory of the shot and thus its range is determined via the height directional angle.
  • the movement of the weapon carrier In order to be able to use the weapon even when the vehicle is moving, the movement of the weapon carrier must be compensated for, ie the weapon must be stabilized.
  • several gyro packages are used as sensors for the primary stabilization of sighting means and the weapon system.
  • Such a gyro package usually includes two uniaxial gyros, which are mounted on the weapon and measure the rotary movements in the elevation and azimuth axes and compensate for each with a closed control loop with the help of directional drives.
  • the edge angle of the weapon must also be known for determining the ballistic data, which is detected by a pilot sensor.
  • gyroscopes are used in the turret and hull to pre-stabilize the weapon.
  • the main battle tank as a direct-facing weapon has visual aids for commanders and gunner with which the position of the target is visually determined. In order to use these sighting devices while driving, they must also be stabilized. If they are primary stabilized, this means that the display units also have two uniaxial gyro packages with corresponding servo drives and control loops. This means that three primary stabilized devices with a total of six turning gyros are available in such a main battle tank. However, these turning gyros work independently of one another, so that if one gyro packet fails, the other cannot perform its function. In addition, the known gyroscopes are not suitable for providing guidance information, for example in the form of navigation data.
  • the invention has for its object to provide a fire control and navigation system for moving weapon carriers, which measures all the information necessary for fire control and stabilization of the weapon under all conceivable driving conditions of the weapon carrier and target and additionally provides guidance information for tactical tasks.
  • the accuracy of the overall system is to be improved and new tactical applications are to be developed.
  • the digital navigation system according to the invention using strapdown technology does not require any complicated, complex mechanical parts apart from the inertial sensors. It includes only two biaxial dry, dynamically tuned gyros and three uniaxial accelerometers, which are combined with the gyros in a single sensor block. This means that all functions according to the task are completely autonomous and can be carried out from the outside without the possibility of interference.
  • the strapdown sensor block comprises two dry, dynamically tuned two-axis gyros 1 and 2 arranged perpendicular to one another and three uniaxial accelerometers 3, 4, 5 aligned in the three spatial axes.
  • the accelerometers 3, 4, 5 determine the vehicle accelerations in three orthogonal ones Axes and the gyros 1, 2 also measure the rotation rates in three orthogonal axes.
  • the vehicle speed can thus be determined by integrating the accelerations taking into account the direction.
  • the distance traveled is obtained by integrating the vehicle speed. If the starting position and the initial speed of the vehicle are known, then navigation is possible, that is, the current vehicle position can be calculated continuously in three-dimensional space.
  • the measured rotation rates can be used for primary stabilization of the vehicle carrying the gyroscope and can also be used for secondary stabilization of another device.
  • FIG. 5 gives an overview of the fire control system.
  • a strapdown sensor block 8 is integrated in a target device 6, which is primary stabilized with the aid of controllers and servo drives 7.
  • the rotation rates determined for stabilization are also used by control electronics 16 of a weapon 15 for secondary stabilization of the weapon.
  • the weapon can be post-stabilized using a fire control computer 10.
  • the fire control computer 10 calculates the ballistic values as well as lead and attachment depending on the type of projectile. Using a directional handle 9, the command variable can be given as a target speed on the target device and weapon.
  • a navigation computer 11 determines speed and position based on the carrier vehicle from rotation rates and accelerations, measured by the strapdown sensor block 8.
  • a display and operating device 13 is used to display the determined values, for example the position in UTM coordinates, and for input, for example the start position.
  • Additional sensors 14, such as thermal imaging night vision devices, can be integrated into the system as a supplement. Due to the multiple use of the sensors, the position data of the carrier vehicle are determined beyond the actual stabilization task from the measured translational accelerations and the rotation rates.
  • the system also determines the position angles of the weapon, which are required to compensate for tilting and to calculate the ballistic angles.
  • the movement of the weapon when fired is fully known, so that ballistic disturbances can be compensated for.
  • the weapon can be point-stabilized if the target distance is known, as FIG. 6 illustrates. Furthermore, the actual target movement can be determined via the directional movement, since the vehicle movement is known. This enables correct dynamic lead formation with simultaneous correct ballistic compensation.
  • the weapon can also be used in an indirect shot, that is, without a direct line of sight to the target.
  • This allows the weapon to be used for new tactical tasks such as helicopter defense and to support artillery in the event of a fire.
  • the navigational ability offers the commander additional guidance, in particular the display of his own position and the display of the position of other vehicles of his squad, so that the visual connection of the friendly vehicles to each other for tactical guidance is no longer an essential requirement. This means that it can be used without degrading the system performance even under difficult visibility conditions, for example under ABC conditions or at night. The same applies to the fight in monotonous or foreign terrain, in which no landmarks can be found.
  • the system according to the invention operates with little wear and is maintenance-free. Due to the digital system design, the measured values can be used several times and intermediate results can be used. This results in a significant improvement in the performance of the overall system and new application possibilities are opened up.
