Definitions

  • the invention relates to a method and a device for correcting dynamic gun errors according to the preamble of claims 1 and 4, respectively.
  • the gun structure and the Gun barrel when dynamically firing series fire due to high forces.
  • the weapon barrel Before the start of a series fire, the weapon barrel is aimed at a target or at one Place where the projectiles to be fired meet with the aim, but directed
  • the forces that act during the series fire result in an uncontrolled one, among other things spatial movement of the weapon barrel muzzle area, through which firing errors and a decrease in the probability of being hit.
  • Such Errors are considered dynamic gun errors within the scope of the present description or muzzle direction error.
  • the object of the invention is seen in proposing a precise, efficient method and an economically advantageous and field-compatible device for carrying out the method, by means of which the errors mentioned are avoided or at least greatly reduced and a higher probability of being hit.
  • a measurement is made during a series fire the movement of the muzzle region of the weapon barrel, in short the weapon barrel muzzle region, instead of.
  • the measurement signals obtained in this way are used for a correction to carry out the original direction of the weapon barrel, or to the position of the Gun barrel, that is, its elevation and azimuth, to change the movement the weapon barrel muzzle area is compensated. That way you can Mistakes in firing can be avoided.
  • an angle measuring device is arranged, which has two measuring elements in one The plane is offset by 90 ° to one another transversely to the longitudinal axis of the weapon barrel.
  • the angle measuring device is in particular in a particularly advantageous embodiment of the invention formed by two measuring elements, each of which has a fiber gyroscope. Shortly before the series fire is triggered, the fiber gyro angles become with the encoder angles of the gun. The movement is measured during the series fire the weapon barrel muzzle area by the deviations of the measured fiber gyro angles be continuously determined from the encoder angles. So be measured Deviations in the direction of the weapon barrel muzzle from the originally determined and set target direction. The measurement signals obtained in this way are after they have been converted have been used to control the drives used for straightening the weapon barrel are provided.
  • a gun 1 which is particularly suitable for rapid series fire.
  • a measuring device comprising a first measuring member 4 and a second measuring member 5 , which are offset by 90 ° to one another in a plane perpendicular to the longitudinal axis of the gun barrel 2 of the gun 1 .
  • An offset of 90 ° is particularly advantageous, but an offset of less than 90 ° is also possible.
  • the first measuring element 4 is assigned to a drive for pivoting the weapon barrel 2 for adjusting the elevation and the second measuring element 5 is assigned to a drive for pivoting the weapon barrel 2 for adjusting the azimuth; these are the drives which are already present on such guns for aiming the weapon barrel in elevation ⁇ and azimuth ⁇ and which are therefore not shown and described in more detail.
  • the measuring elements 4 and 5 have the purpose of detecting the movement of the muzzle of the weapon barrel 2 during a series fire and converting it into electrical measuring signals or output signals.
  • Each of the measuring elements 4, 5 has a fiber gyroscope that works according to the gyro measurement principle.
  • a fiber gyro essentially consists of a ring interferometer, in which one The laser generated rays circulate in opposite directions and interfere with each other, whereby the Ring for the beam path from a number of turns of an optical fiber arrangement is formed, into which the beam generated by the laser is coupled. If such Ring interferometer arranged around an axis perpendicular to the plane of the beam path If, as is known from the Sagnac experiment, there is a path difference from the opposite beams emitted by the laser and thus a shift in the interference fringes generated by them or a change in the interference pattern. These changes of Interference patterns are detected by a detector and output signals in the form of Turning rates or changes in angle given. In other designs of fiber gyros the Doppler effect between the opposing beams is used to determine who uses angle changes.
  • the measuring device is connected to a control device. 2 , the measuring element 4 is connected to a first input e1 of a first control unit 10 .
  • the control unit 10 is connected on the output side via lines R, S, T to a motor 11 of the one drive, namely that for pivoting the weapon barrel 2 in the vertical direction or for adjusting the elevation.
  • the motor 11 is directly connected to a resolver 12 , further via a planetary gear 13 with a load 14 , which corresponds to the parts of the gun 1 to be moved, and further via a measuring gear 15 with an encoder 16 .
  • the resolver 12 is connected to a second input e2 of the control unit 10 , and the encoder 16 is connected to a third input e3 of the control unit 10 .
  • a reference speed or a reference position are fed to the control unit 10 via a fourth input e4 and a fifth input e5 .
  • the further drive which is provided for pivoting the weapon barrel 2 to adjust the azimuth, is controlled by means of a further control device, not shown, which is similar to the control unit 10 described with reference to FIG. 2 .
  • the gyro angles of the measuring elements 4 and 5 are compared with the encoder angles of the gun 1 .
  • the deviations of the fiber gyro angles from the encoder angles are evaluated in the control unit 10 and used to control the drives for the pivoting of the weapon barrel 2 .
