METHOD FOR OPERATION OF AUTOMATIC SMALL ARMS FOR FIRING BY HIGH-POWER AMMUNITION AND WEAPON BASED ON IT Russian patent published in 2004 - IPC

FIELD: small arms, applicable in making of constructions for firing by ammunition with a high recoil momentum.

SUBSTANCE: the automatic small arms has a barrel with a cartridge chamber for placement of ammunition in it, bolt and a box. The barrel is installed for forward motion in the longitudinal guides of the box and is kinematically linked with the bolt by means of a mechanism for translational motion of the barrel simultaneously with the bolt in opposite directions. The method for operation of the automatic small arms in the process of firing by high-power ammunition consists in motion of the bolt spring-loaded by the return spring under the action of the recoil momentum, this motion is retarded by an increase of the reduced mass of the automatic movable system due to the use of a spring-loaded movable barrel kinematically linked with the bolt, simultaneously providing for motion of the bolt and reducing the motion and the speed of the bolt.

EFFECT: enhanced total reduced mass of the movable system, adjustable both to the higher and lower sides, provided barrel and bolt motion in opposite directions with a reduced motion and speed of the bolt.
