Definitions

  • the invention relates to a weapon barrel with a swirl profile with a variable twist angle and a last force acting when firing a projectile according to the preamble of claim 1.
  • Such weapon tubes are known in which different types of twist are provided can cause different profiles of the groin force over the movement of the spin-stabilized projectiles. Constant and parabolic swirl courses are most often used.
  • the object of the invention is to provide a weapon barrel according to the preamble of claim 1, which within the production tolerances has an exact swirl course corresponding to various desired properties of the last force.
  • the standardized groin force curve R n (x) (solid line) shown in FIG. 1 ideally fulfills the requirements set over the barrel length x.
  • the constant groin force over a large area starting at a value x 2 of the pipe length results in a full groin force curve and a low twist moment.
  • the actually desired groin force curve R (x) results from the standardized groin force R n (x) by where R max is a maximum value of the groin force that is still to be determined, which depends, among other things, on the final twist angle ⁇ E.
  • FIG. 7 shows the maximum groin force as a function of the normalized groin force curve on which it is based.
