Definitions

  • the invention is concerned with an acceleration limitation of gun-induced movements, caused by, for example, sea state, on a weapon, such as a machine gun.
  • the control of gun-induced movements to stabilize the machine gun bore axis implies the use of partially sensitive measurement systems, e.g. Gyroscopes, advance. Especially during the bursts of fire, especially during longer fire sequences, these measuring systems are influenced to a large extent by occurring recoil forces of the weapon, depending on the location. The measuring system thus incorrectly measures a carrier-induced movement, even if the gun or the weapon is mounted on a stationary platform during the burst of fire. This erroneously measured movement leads to an overreaction in the gun control, that is, if they are taken into account in the gun control. This in turn causes a deterioration of the hit image such that it leads to an undesirable increase in scattering (sigma value of the standard deviation) in the event of a burst of fire.
  • partially sensitive measurement systems e.g. Gyroscopes
  • a ship motion prediction device discloses the DE 603 18 394 T2 ( EP 1 474 326 B1 ).
  • the DE 38 82 347 T2 ( EP 0 321 127 B1 ) refers to an electronic tilt measuring system.
  • a stabilization system for a rifle is the DE 698 32 339 T2 ( EP 0 898 144 B1 ) removable.
  • an accelerator is known from gun-induced movements on a weapon installed on a carrier moving with an object.
  • the invention has the object to avoid the aforementioned disadvantages.
  • the invention is based on the idea of optimizing or adapting the meeting behavior or the meeting pattern to the carrier-induced movements.
  • the aim is to achieve an optimized compromise between the stabilization performance and the impact of machine guns on guns during fire sequences.
  • the data measured by the measuring system (s) is based on a history-based, adaptive acceleration limitation.
  • the measurement data of / the measuring system / (e) are continuously stored. If these are older than a few seconds, this data can be deleted and no longer used so that there is always an updated history of data from the measuring system used for the acceleration limitation.
  • the maximum occurring during the history accelerations are determined.
  • the maximum value of the acceleration thus continuously adapted to the respective carrier movement is used during each fire sequence in order to limit the measurement data of the measuring system (s) in the form of an acceleration limitation and thus indirectly also the response of the gun control, ie the stabilization of the tube axis.
  • the overall gain in stabilization performance is optimally adapted to the respective boundary conditions by the use of simple measuring systems, achieving the best possible meeting point (lowest possible sigma value of the standard deviation) for bursts with regard to these influences.
  • Proposed is an acceleration limit of gun induced movements on a weapon installed on a moving carrier (e.g., ship, vehicle, helicopter, etc.).
  • a moving carrier e.g., ship, vehicle, helicopter, etc.
  • the movement of the wearer during the time in which no use of the weapon is measured.
  • These continuously measured data are stored and used to determine a history of the maximum occurring accelerations of the carrier. During a fire sequence of the weapon then these measured data are taken into account for the gun control.
  • the carrier 3 is in turn fixedly mounted on a deck 5 of a ship (or a vehicle or the like). Due to the movement of the ship, caused by swell, the system includes a non-illustrated, but well-known gun control in order to align the weapon to a target during the sea constant or targeted.
  • the measuring system 4 may be a gyroscope. This is already used in practice for gun control itself.
  • the function is as follows: During the time in which no use of the weapon 1 takes place, measurement data of the measuring system 4 are continuously determined. These are written to a computer 6 and stored. The maximum acceleration occurring during the recorded history (acceleration values) is determined from the measured data.
  • these measurement data are used as a continuously adapted maximum value from the computer 6, which are then used for limiting the measurement data of the measurement system 4.
  • the recoil forces occurring during the fire sequence in the measuring system 4 which are substantially larger than the carrier-induced movements, are not taken into account in the gun control.
  • These data falsified by the recoil forces are limited according to the invention during the fire sequence with the maximum value of the stored measurement data.
  • the solution is not limited to use on ships, but can also be used in vehicles in motion, especially in the field, etc. application.
