Definitions

  • the invention relates to a device for testing the dynamic behavior, in particular the accuracy, of barrel weapons.
  • a stationary device is already known with which the static behavior of guns or launch containers for missiles, in particular tube weapons, can be tested. This means in particular the test of the stabilization devices and the devices for weapon control.
  • the known stationary device is used in particular for the comparison of the stabilization and control devices of the gun mentioned with the radar and fire control device of the weapon system.
  • the video camera can preferably be attached to or in the barrel of the barrel weapon with the aid of an adapter such that the optical axis of the video camera coincides very precisely with the core axis of the barrel.
  • the image from the video camera is fed to the image display device in a known manner, for example with the aid of a corresponding cable, and is reproduced by the latter.
  • the image display device is designed as a portable device or a device that can be inserted into a conventional frame.
  • the image display device generates a crosshair or square of errors, which is superimposed on the image supplied by the video camera and displayed together with it.
  • the test device can also be used to test the dynamic behavior of twin guns.
  • it contains a further video camera, which can be attached to or in the barrel of a second barrel weapon in the same way as the first.
  • the images supplied by the two video cameras are superimposed on one another in the image display device and displayed together. If both tubes are aimed exactly at the same target, the image display device delivers a sharp image of the target.
  • a poorly aligned alignment of the two tubes can be recognized from the blurriness of the image and can be measured precisely using the calibrated crosshairs.
  • the stabilization device of a gun installed on a speedboat has to compensate for the movements of the ship's hull caused by the swell or by machine maneuvers.
  • the position of the gun barrel in the room is determined by means of a fire control device, which the gun barrel must assume in order to combat the target. Since the relative position of the target to the gun changes constantly with mobile weapon systems to combat moving targets, the gun has to be tracked continuously.
  • the fire control device provides guide values that take into account the ballistic properties of the projectiles and in particular the wind conditions.
  • the inner axis of the tube and the optical connecting line between the tube and the target have a certain angle to one another. Since the test device according to the invention works optically, it is only suitable for testing the accuracy of barrel weapons in which consideration is taken into account in the associated fire control device the so-called lead can be switched off. Without taking account of the lead, the core axis of the tube coincides with the optical connecting line between the tube and the target, ie the target can be seen when looking through the tube.
  • the video camera is attached in the barrel of the barrel weapon to be tested according to a preferred embodiment. This is done with the help of an adapter, whose outer diameter corresponds to the caliber of the pipe. Accordingly, different adapters are required for different calibers.
  • the video camera is a special version, the optical axis of which is precisely adjusted in relation to its housing.
  • the adapter is also manufactured with the greatest precision. This results in an exact alignment of the optical axis of the video camera with the core axis of the tube when the video camera is fastened in the tube.
  • the tube is precisely aligned with the target, the image of the target appears on the image display device exactly in the center of the image.
  • a crosshair or a square of errors is shown in the image to make it easier to identify any deviations. If all systems of the weapon system work correctly, a moving target remains and even when the weapon system is in full swing always exactly in the center of the picture or within the square of the error. Thus, by merely observing the image of the target represented by the image display device over a certain period of time, a statement can be made about the accuracy of the barrel weapon.
  • the image display device for example in the operations center.
  • the video camera can then, for example, be attached to the various guns of the ship one after the other in order to check their dynamic behavior.
  • the image transmission from the video camera to the image display device is preferably carried out via an existing video cable network to which the video camera can be connected in the vicinity of each gun.
  • the advantage of this test device is, in particular, that without any significant effort practically any time, for example after repairs after a long period of non-use or before target practice, a clear statement can be made about the accuracy of a barrel weapon.
  • ammunition can be saved, for example, by avoiding missed shots, as well as time and therefore costs if the useless approach to the shooting range is omitted from the outset.
  • the function of the barrel weapon can be demonstrated impressively, for example for training purposes.
  • FIG. 1 shows the front section of a cannon tube 1 and a video camera 10 with an adapter 4, the video camera being connected to a monitor 20 via a cable 30.
  • the cylindrical video camera 10 with a lens 12 is fixed in an essentially cylindrical adapter 4 with connecting means 5 on fastening webs 14 by screws 16 so that the axes of rotation 3 of the adapter and the camera coincide.
  • the adapter 4 is dimensioned such that its outer diameter corresponds to the caliber of the cannon tube 1, that is to say it is only very slightly smaller than the inner diameter of the cannon tube 1, so that when the adapter 4 is inserted into the tube 1, its axes of rotation 3 also coincide.
  • An edge flange 7 of the adapter 4 also serves as a stop and handle. About other connecting means such.
  • B. Clamping screws (not shown) the adapter 4 can be fastened in the gun barrel 1. This arrangement ensures that the axis of rotation 3 of the lens arrangement 12 is aligned with the axis of rotation or core 3 of the gun barrel.
  • optical signals which are converted into electrical impulses by a semiconductor image sensor (not shown) located behind the lens arrangement 12, are conducted via line 30 to a monitor 20.
  • the image of the target is displayed on the monitor 20 together with a crosshair 22 useful for setting and measuring work. If the gun barrel 1 is aimed precisely at the target, then the image of the target appears on the monitor 20 exactly in the middle of the cross hair 22.
