DEVICE TO REDUCE EXCESSIVE PRESSURE DURING SHOT AND STABILIZATION OF BARREL OF FIREARMS Russian patent published in 2003 - IPC

FIELD: firearms, canon-type artillery. SUBSTANCE: characteristic feature of invention lies in installation of turbofan gear coming in the form of turbine which nozzle apparatus is made fast to barrel and impeller can rotate relative to barrel on bearing on barrel of artillery gun. Thus combined effect which takes form of decreased front of muzzle wave is achieved by way of its destruction and formation of air flow of opposite direction and stabilization of gun barrel while firing thanks to creation of gyroscopic effect. Main property of this effect is property to maintain its position in space stable. EFFECT: device ensures reduction of excessive pressure on positions of gun's crew and increased density of hits. 2 cl, 1 dwg
