OMELYANENKO BULLET SEPARATING FOR SMOOTHBORE WEAPON Russian patent published in 1999 - IPC

FIELD: bullets for smoothbore weapons. SUBSTANCE: bullet has a mushroom- shaped body comprising a subcaliber head section and a tail wad-stabilizer with an obturator in the rear section, turbine in the form of bulges on its peripheral surface and a recess on the front end face that receives the body tail, as well as centering detachable sectors. The front, rear ends of the head section and the tail in the body are made in the form of tapering bulges, and all edges are rounded off. Each turbine bulge has a length exceeding the maximum diameter of the body head section and smoothly turns into the peripheral surface of the wad-stabilizer; a groove with peripheral sides inclined towards the rear part inclined at an angle of 40 to 50 deg. is made on the peripheral surface of the wad-stabilizer opposite the recess end face. The recess end face of the wad-stabilizer has a bulge, whose front side is made as a sucker, and the front part of the recess - in the form of a cone. With its tail the body is installed in the recess of the wad-stabilizer with a clearance of 2.5 to 5 mm between the end faces of the tail and recess bulge, and with a lesser clearance between the rear side of the body head section and front side of the wad- stabilizer. The centering detachable sectors are formed by means of separation into more than 2 parts with an inclination at an angle of 6 to 20 deg. to the longitudinal axis of the caliber hollow cylinder and have on its internal surface similar bulges, with which they are installed on the front side of the head section, and from the out- side they have longitudinal ribs turning into a transverse annular bulge in the rear part. EFFECT: enhanced flight velocity, accuracy of shooting, range of hitting, hitting power, reduced ricochet and recoil momentum at a shot. 1 dwg
