Abstract
The invention concerns the area of arms engineering, in particular, the designs of the fire weapon barrels both smooth-barrel, and rifled, and can be used for manufacture of the fire weapon: artillery, shooting and near fight. Achievable technical result: increase of kinetic energy and initial speed of a fired projectile or bullet, reduction of power expenses for dispersal of a projectile or bullet up to required initial speed. In an offered barrel along the barrel channel cavities hollow (groove) in the form of nozzles Laval or screw cavity for artillery and shooting barrels are carried out. They can be any form for barrels, intended for the weapon of near fight. An offered barrel allows to reduce passing of pushing gases in a backlash between a projectile or bullet and walls of the barrel channel and accumulation of them before a projectile or bullet. This circumstance permits to reduce condensation of gases in the barrel channel before a projectile or a bullet. That raises efficiency of chemical energy transformation of gunpowder charge into kinetic energy of a projectile or bullet and reduces power expenses by dispersal of a projectile up to required initial speed, or allows increase of barrel speed of a bullet or projectile up to 1500-4000 m per sec.
Claims
1. Weapon barrel, containing the case (6) and the barrel channel (2) or liner, the internal surface of which has a number of cavities, distinguished by that in barrel , intended for use in artillery systems, the cavities (1) are carried out with walls diverging in the direction of the end of the barrel muzzle and located with decreasing intervals between them along the barrel up to a place equal 0,1-0,5 length of the barrel, place of as much as possible developed pressure of gun-powder gases, and with increasing intervals between them from this place up to the end the barrel muzzle, thus the longitudinal size of cavities does not exceed length of a shell lead part.
2. Weapon barrel, containing the case (6) and the barrel channel (2), the internal surface of which has a line of cavities (1), distinguished by that in barrel , intended for the shooting weapon, the cavities (1) are carried out with walls diverging in the direction of the barrel muzzle and are located in regular intervals along the barrel, since distance, not smaller twenty calipers from a breech part of the barrel thus the longitudinal size of cavities does not exceed three calipers.
3. Weapon barrel , containing the case (6) and the barrel channel (2), the internal surface of which has a line of cavities (1), distinguished by that in barrel, intended for the shooting weapon, the cavities have a variable diameter, increasing in the direction of the barrel muzzle and carried out as a screw cavity, since distance not less than twenty calipers from a breech part of the barrel, thus the step of the cavity screw does not exceed five calipers.
