Definitions

  • the invention relates to a device for stabilizing a on a low dynamic carrier e.g. a tank, ship or the like, mounted higher dynamic device, in which the movements of the low dynamic carrier are detected by a central sensor block on the carrier.
  • a low dynamic carrier e.g. a tank, ship or the like
  • low-dynamic carrier is understood to mean a body of comparatively great inertia, which changes its position in space only comparatively slowly when a certain force is applied.
  • higher-dynamic device is understood to mean a lighter body that comparatively quickly when subjected to force can accelerate.
  • a weapon tracking system is known, in particular for ship guns, in which control loops are used for weapon tracking, to which a command variable generated by a gyro system and corresponding to the angular velocity of the carrier is subordinate.
  • the gyro system which is fixed to the support, comprises three gyroscopes without an accelerometer. For a simple technical adjustment of the gun alignment, two separately implemented amplifiers are used in an analog system.
  • DE-A1 3 332 795 discloses a fire control and navigation system for movable weapon carriers, in particular for battle tanks, in which a single central sensor block using strapdown technology is used for primary stabilization, for example of a target or sighting device, or for secondary stabilization of a weapon.
  • a single central sensor block using strapdown technology is used for primary stabilization, for example of a target or sighting device, or for secondary stabilization of a weapon.
  • which comprises two biaxial, dry, dynamically tuned gyros and three uniaxial accelerometers, and in which the acceleration values or rotation rates are output and processed in digital format.
  • the line of sight must also be stabilized with a central sensor package.
  • a relatively small deflection mirror with a much higher dynamic range than the carrier (tank) can be stabilized.
  • the gyroscopes and accelerometers must therefore be attached to the deflecting mirror and the inertial sensors and the entire digital processing must be designed for the high bandwidth of this deflecting mirror. This places high demands on the dynamics of the sensor block as a whole and on the bandwidth of the digital control in particular.
  • the invention has for its object to stabilize devices mounted on a comparatively low-dynamic carrier with significantly higher dynamics in their position in space in a technically simple manner and with flexible adaptation options to the type, number and individual dynamics of the individual device, the common inertial sensors on Carriers are attached.
  • the device according to the invention it is possible to stabilize the devices themselves with the aid of a common inertial sensor package (e.g. strapdown system) on the carrier and with angle sensors or rotary speed sensors or angle measuring devices, in particular resolvers. It is of great importance that the bandwidth of the inertial sensor package only has to be so large that the movements of the low-dynamic carrier are correctly recorded.
  • the bandwidth of the carrier is generally significantly smaller than that of the devices to be stabilized.
  • an analytical platform as an inertial sensor package, it also continuously provides the position and location of the tiger itself and the quantities derived from it for additional tasks, for example as part of a central fire control system. In principle, the number of devices to be stabilized and their bandwidth is not limited.
  • a main battle tank 1 with a turret 2 is provided as a low-dynamic carrier.
  • a number of devices to be stabilized are mounted in the turret 2, in particular a cannon 4 as the main weapon of the tank, a commander's periscope 5 and a gunner aiming device 6.
  • the central sensor block 3 is mounted as a complete unit in the turret and detects the relatively slow turret movements relative to one earth fixed navigation coordinate system.
  • an inertial central Sensor systems with accelerometers provide data on the location, location and movements of the wearer.
  • the central sensor block (the analytical platform) provides the position of the vehicle in an earth-fixed navigation system, so that orientation in unknown terrain and in poor visibility or under difficult environmental conditions is facilitated.
  • the strapdown system also provides data on the speed and angular velocity of the tower for better fire control, for example to correct the muzzle velocity of the projectile of the cannon 4. All of this data is provided via a data bus 11 (FIG. 2). Furthermore, with the aid of distance measurements from the armored vehicle to the target, point stabilization and dynamic lead formation can be implemented exactly.
