SMALL-CALIBER ARTILLERY PROJECTILE WITH POLYMER GUIDANCE DEVICES Russian patent published in 2005 - IPC

FIELD: artillery projectiles used for aircraft artillery weapons.

SUBSTANCE: proposed artillery projectile has casing with main guidance device, core, priming charge, additional guidance device which is made from polymer material as main guidance device and casing forming monolithic structure; length of core is increased at retained mass of projectile. Proposed projectile has improved characteristics of its centering during motion in bore at fully eliminated thermoplastic wear and reduced intensity of wear of inner surface of bore. Provision is also made for compensation of thermal expansion of inner diameter of bore at automatic firing, reduction of initial disturbances at expelling from bore and consequently reduction of projectile dispersion at firing.

EFFECT: enhanced efficiency; reduced dispersion of projectiles in firing.
