DEVICE FOR REDUCING IMPACT OF RECOIL MOMENTUM OF FIREARMS FIXED ON INSTALLATION Russian patent published in 2019 - IPC F41A23/52 F41A21/44 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to artillery mounts. Device for reducing the impact of the recoil pulse of a firearm mounted on the apparatus has a casing with a brake-compensator and is located in the zone of muzzle of the barrel of the weapon. On the brake-compensator openings for powder gases are made, the rear row of windows of the brake-compensator is covered by the barrel of the weapon and opens when it is rolled back. Method of reducing the impact of recoil momentum of a firearm fixed on an apparatus includes shooting, occurrence of a recoil pulse I₁, acting on installation, at that part of powder gases expires in brake-compensator, in which during the barrel recoil the extreme row of windows is additionally opened and pulse I₂ appears from pressure of powder gases, acting in opposite recoil momentum I₁ direction, which leads to reduction of resultant recoil pulse I₃, acting on the plant.

EFFECT: technical result is reduced impact of recoil of firearms on installation, possibility of using device on light carriers, such as aircraft and helicopters, boats, etc.
