Definitions

  • the invention relates to a weapon barrel according to the preamble of patent claim 1.
  • Such a gun barrel can be used, for example, as a heavy, large-caliber gun barrel for main battle tank guns.
  • Gun barrels are known in manifold designs. The aim was always to achieve an increase in performance by increasing the accuracy, for which purpose, for example, the gun barrels were lengthened, the spans of the barrel storage varied or other measures were taken to reduce the angle of departure.
  • a design has emerged as a standard form, in particular in the case of gun barrels for main battle tank cannons, in which the barrel has a multiply offset jacket which is stored in a bearing with short spans. To increase the inertia and reduce the vibration behavior of the pipe the focus of the returning mass was shifted from the area of the bearing towards the pipe mouth.
  • a device on weapon tubes to reduce the exit error angle of a projectile is known from DE-PS 19 11 067. Bending vibration damping stiffeners are arranged on the weapon barrel in the front length range.
  • the accuracy is determined by the exit error angle at which the projectile leaves the pipe mouth, deviating from the target direction.
  • the invention has for its object to provide a weapon barrel of the type mentioned, in which the tube bending vibrations are influenced so that a constant exit error angle is set, with the aim that a more effective exit error angle is entered into the fire control computer and thus to increase the accuracy and leads to a significant increase in performance.
  • the object is achieved in that in a cannon tube according to the preamble of claim 1, the tube in the static and dynamic state in the area between the pipe mouth and storage has a frustoconical tubular jacket with a continuously unbending bending line and in a cylindrical area of the tubular jacket for the tube storage passes, with the cylindrical portion of the Pipe storage a max. Length does not exceed 7 D and the center of gravity of the returning mass is in the area of the truncated cone-shaped tube jacket.
  • the invention offers further advantages in that not only is vibration damping achieved by increasing the inertia, but the return travel of the returning parts is reduced and the outgoing speed v of the projectile is increased by the long tube construction.
  • the weapon barrel 1 with the core barrel length L and the caliber diameter D has a ratio L / D> 52 and a span a of the barrel bearings 9 and 11 of ⁇ 7 D.
  • the barrel jacket has a cylindrical region 10.
  • the weapon barrel 1 extends to the barrel mouth 2 without a truncated cone.
  • the bearing 9, 11 of the weapon barrel 1 is in the cradle, not shown (its construction is not essential to the invention).
  • 5 is the center of gravity of the gun barrel and 6 the center of gravity of the parts returning with the barrel during the shot.
  • the returning parts are formed from the pipe recoiler, the pipe brake and any other parts, such as the loading device, as a so-called returning mass.
  • the center of gravity 6 of the returning mass lies in the frustoconical area of the barrel 1 in front of the bearing 9 and ensures a stable contact of the weapon barrel between the bearing points 9, 11 and the cylindrical barrel region 10.
