STATIC MUZZLE BRAKE Russian patent published in 2022 - IPC F41A21/00 

FIELD: muzzle brakes.

SUBSTANCE: muzzle brake contains a body with an annular, conical and cylindrical parts, tides with windows made in them. The inner diameter of the annular part and the minimum inner diameter on the conical and cylindrical parts of the housing are made equal to the barrel caliber d in the form of two arcs with an angular size of 90 degrees and are symmetrical with respect to the central vertical and horizontal planes of the brake housing. The conical part 1.19d long and the cylindrical part 2.5d long are the lugs of the body in the horizontal region symmetrically about the central vertical and central horizontal planes with a profile width equal to 2.12d, a profile height equal to 1.37d. Side windows are made in the tides of the cylindrical part of the brake housing.

EFFECT: invention provides an increase in the momentum of the muzzle brake pulling force, a decrease in the excess pressure of powder gases in the direction of calculation.
