Abstract:
A weapon tube for firing spin-stabilized projectiles with driving bands, comprising: a weapon tube having rifling in the form of a plurality of helical grooves cut over the entire periphery into a tube inside wall, with the grooves being such that a respective rifling groove flank forms on both sides toward a rifling groove bottom and encloses a respective rifling groove flank angle .alpha., and such that lands exist between the respective rifling grooves, which grooves and lands together a rifling profile; and wherein: the tube has an increased number of rifling grooves relative to a smaller number of such grooves in a shorter weapon tube; the rifling grooves and lands are configured such that with the increased number of grooves, a total volume of the rifling grooves is equal to that for the small number of rifling grooves, and the rifling groove depth and spin angle (.delta.) are the same for the increased number of rifling grooves as for the smaller number of rifling grooves.
