METHOD TO THROW OGIVAL BODY WITH HIGH INITIAL SPEED FROM RIFLED BARREL OF WEAPON AND AMMUNITION FOR ITS REALISATION Russian patent published in 2011 - IPC F42B5/02 F42B29/00 

FIELD: weapons and ammunition.

SUBSTANCE: method to throw body from a weapon barrel consists in creation of powder gases pressure in hollow body, rotary torque to boost body in a weapon barrel, its transformation into accelerated rotation in the weapon barrel. Simultaneously pressure of powder gases provides for cutting of thread on body and reciprocal motion of piston inside body. Reciprocal motion is transformed into power rotary torque of body in barrel, where its axial force is summed with axial force of powder gases pressure at bottom of thrown body. Throwing device comprises hollow ogival body in the form of bullet or projectile, piston, lugs and stop ring. Coaxial rectangular guiding ledges, corresponding to turns of hollow body, are arranged on surface of piston. Stop ring is installed in slot on inner surface of body at the end of trapezoidal thread. Lugs slide in rectangular slots, which are equal in width and height. Inside hollow body there is a cylindrical stop, which serves as axis of body rotation in the weapon barrel. Stop is installed with rest against bottom of inner cavity of thrown body. Stop is arranged with central end cone hole and ogival surface.

EFFECT: invention provides for throwing of ogival body with high initial speed from weapon barrel.
