Definitions

  • the invention relates to an arrangement for determining the hit position and / or the speed and / or the impact angle of a projectile hitting a target at supersonic speed, with several acoustic sensors being arranged on the target in two planes parallel to one another and to the target surface and on each of the two Levels are distributed so that they encompass the expected trajectory of the projectile and emit signals which are fed to a computer which, according to the chronological order and the time interval in which the signals are emitted by the individual sensors, the storage of the projectile from Target point calculated.
  • a computer which, according to the chronological order and the time interval in which the signals are emitted by the individual sensors, the storage of the projectile from Target point calculated.
  • targets are mostly used, which are printed with rings and sector boundaries and are either observed directly or transported to the shooter after a series of shots. In both cases it is necessary to replace the target after a limited number of shots.
  • hit positions for further processing of the hit images must be tapped from the disk by means of a computer and entered into the computer.
  • a device for determining the direction of the projectile in which the projectile penetrates two levels covered with a substance, thereby generating a sound wave in the substance, which is transmitted in the substance to acoustic sensors, which according to the address different running times and feed their signals to a computer.
  • the sensors do not respond to the head wave of the projectile but to a sound wave generated by the projectile in the substance.
  • the device also has the disadvantage that, for reasons of measurement accuracy, the substance must be homogeneously and isotropically tensioned. Furthermore, the projectile loses kinetic energy when the substance penetrates, which makes measurement more difficult.
  • the measurement is also adversely affected by other acoustic influences that generate sound waves in the substance, such as the head wave of the projectile, and finally the substance must be renewed after each penetration of even one storey because the homogeneity is disturbed. This makes the use of machine guns impossible.
  • the invention has for its object to provide an arrangement of the type mentioned, which allows to determine and evaluate a precise position of the points in the plane formed by the acoustic sensors and with a high firing sequence even at an oblique shot the projectile penetrates these levels.
  • the planes receiving the sensors merely represent imaginary, ideal planes, so that the sensors can only be influenced by head waves propagating in air when another medium is eliminated.
  • the sensors are arranged in each of the two levels on a frame encompassing the trajectory, the two frames advantageously being combined to form a body.
  • the frames or the structure are rectangular and are equipped with sensors on each side.
  • the arrangement according to the invention can also serve to detect the trajectory not only in front of the target but over its entire length. This is done in that sensors are arranged in two planes at each measuring point at measuring points arranged at predetermined intervals along the trajectory of the projectile, the planes being at least approximately perpendicular to the trajectory and the sensors encompassing the trajectory. This makes it possible to record the values on the trajectory that can be measured with the arrangement according to the invention.
  • FIGS. 1 and 2 show an exemplary embodiment of the arrangement according to the invention in a partially schematic representation, but for reasons of clarity only those for measuring the vertical one Deviation of the hit position required sensors are shown.
  • Figure 1 shows a structure 1, which includes the front frame 2 and the rear frame 3.
  • the sensors are labeled So 'and Su' on the front frame 2 and So and Su on the rear frame 3.
  • the vertical distance between the upper and lower side of each frame and thus between the sensors of the pair So 'and Su' as well as So and Su is S, the horizontal distance between the frame and thus between the sensors of the pair So and So 'as well as Su and Su 'is denoted by b.
  • S the distance between the top and bottom of the frame, i.e. the inside width of the frame.
  • ⁇ the angle between the floor trajectory and the perpendicular to the hit image level.
  • each side of the two frames is equipped with a plurality of sensors which are connected in parallel or in series, either directly or via amplifiers.
  • the hit position, speed and angle of impact are advantageously calculated by an EDP system.
  • the speed of sound as well as the wind speed and direction can be entered into the computer.
  • the speed of sound can be measured in the measuring section in a manner known per se.
  • Wind speed and direction are also determined and measured in a manner known per se.
