Definitions

  • Spin-stabilized projectiles are used in particular for artillery ammunition with a guide band arranged at the rear that is pressed into a corresponding dovetail groove of the projectile.
  • the guide band can be made of one or more parts, whereby in the event of a multiple part guide band, the axially adjacent annular sub-guide bands are also located within the dovetail groove of the projectile.
  • the sub-guide bands can be made of different materials (e.g. of brass and soft iron) (DE 198 18 411 A1, which corresponds to U.S. Pat. No. 6,536,353).
  • each of the sub-guide bands is arranged in a separate groove of the projectile.
  • the shape and arrangement of the grooves is dependent on the respective application, whereby the shape of a dovetail groove presents itself as preferred—indeed inter alia a guide band is known from U.S. Pat. No. 2,809,587 A, which comprises a plurality of thin ribs that are spaced apart and that are filled with a filler material forming the guide band, but the technical implementation is very costly. In addition, this can also lead to tearing of the sub-guide bands.
  • the sub-guide bands can be made of the same material or of different materials, in order, for example, to ensure both high wear resistance and good slip capability.
  • the first sub-guide band looking in the firing direction can be made of brass and the second sub-guide band can be made of soft iron.
  • the projectile 1 comprises a guide band 4 that includes preferably two annular sub-guide bands 5 , 6 arranged axially one after the other.
  • the first (leading) sub-guide band 5 can be made of brass and the second (rearmost) sub-guide band 6 can be made of soft iron.
