PROJECTILE Russian patent published in 1998 - IPC

FIELD: projectiles with devices for spin stabilization produced under the action of gases by means of rigidly attached fin assembly and inclined grooves. SUBSTANCE: projectile has a body with aerodynamic blades and gas turbine arranged on its surface. Aerodynamic blades, with a retainer mounted before them, are positioned on the back cone with under- cutting of the bottom section and inclined towards the centering helical bulges of the turbine separated by an annular groove. The height of the bulges is commensurable with the boundary layer thickness. EFFECT: enhanced accuracy of fire. 3 dwg
