Patent UA-74570-C2 (UA)
Title: Weapon for missile shooting and recoil control mechanism for weapon
IPC: F41A25/12
Filed: 2001-03-02
Abstract: A recoil control mechanism for weapon which fires a projectile which is characterised by the generation of a forward counterforce to the rearward recoil simultaneously with absorption of rearward recoil force upon initiation of propulsion of the projectile. The forward counterforce is generated by propelling a first mass forwardly upon firing the projectile and substantially simultaneously propelling a second mass rearwardly for absorbing some of the recoil force. In one mechanism (10), the first mass may be the weapon's barrel (12) and the second mass its breech block (14). Expanding gases (36) from detonation of propellant in cartridge (24) enter a reaction volume (28) between the barrel (12) and breech block (14). There gases drive barrel (12) forwardly against force transmission spring (16) to impose a forward counterforce on the weaponÆs frame (18). Substantially simultaneously recoil from detonation of cartridge (22) together with the gasses (36) in reaction volume (28) drive breech block (14) rearwardly against force absorbing spring (20).
