<p>The invention concerns engineering of arms in particular to barrels of artillery systems shooting weapon and weapon of near fight. The achievable technical result is the increasing of kinetic energy of a bullet or shell and increassing of the barrel resource. The offered weapon barrel consists of the case and barrel channel. The threads are carried out on an internal surface of the channel which in cross section have the gear form and are formed of picking and inactive facets. In an offered barrel the picking facet has the greater angle of attack than in an inactive one and in that specific case can be carried out radial. The inactive facet is carried out concavely and the transitions between facets are carried out smoothly. The offered barrel construction unites in itself useful properties of rifled and polygonal barrels.</p> |
