ARTILLERY JET PROJECTILE Russian patent published in 1999 - IPC

FIELD: artillery weapon. SUBSTANCE: projectile uses a rocket booster with a nozzle unit and tail cone, whose open inner cavity is formed around the nozzle unit. A tapered surface expanding towards the space behind the projectile is formed on the back end of the tail nose. The nozzle unit projects behind the tail cone, and a stepped cylindrical surface is made on its outlet, the smaller step rests against the end of the larger step; and rigidly attached to the nozzle unit is a member for feeding in the form of a disk with through holes. The disk has a tapered surface on the front end and on outside diameter providing for its engagement with the cradle of gun- howitzer at loading and at the same time preventing aerodynamic resistance of the disk in trajectory. EFFECT: enhanced reliability of projectile functioning. 2 dwg
