  • Patent number: 11067354
    Abstract: A breech for noise reduction in a recoil-less weapon is described. The breech is adapted to be arranged in fluid communication with a launcher of the weapon to release exhaust gas. The breech comprises a venturi tube. The venturi tube has an inlet at a first end adapted to be connected to the launcher, and an outlet for releasing the exhaust gas at a second end, wherein the area of the outlet is larger than the area of the inlet. The venturi tube further comprises an exhaust gas controlling element formed at the venturi tube structure. The exhaust gas controlling element is arranged to control the release of exhaust gas so as to decrease a sound pressure peak at the weapon. The inner envelope surface of the venturi tube is configured, such that the inner envelope surface does not alter or at least has a very small influence on recoil characteristics of the weapon.
