ABSTRACT:
A redundant ammunition flow device for supplying divided, large caliber ammunition to a loading tray of a gun mounted on a turret of a vehicle for adjustment in elevation about a trunnion includes at least two magazines disposed in the vehicle chassis. Each magazine is a closed loop and includes a plurality of first holders that accommodate in an upright position either a projectile or a propelling charge column which make of the ammunition. A guide formed of a ring segment is fixed to the chassis concentric with the turret rotation axis. Two ammunition transporters are mounted for displacement on the guide to receive at a respective transfer position either a projectile or a propelling charge column from the first holders. Each transporter includes a rotary arm carrying a feed arm supporting second holders for holding a projectile or a propelling charge column. Two ammunition transfer arms are arranged, one on each side of the gun, for receiving either a projectile or a propelling charge column from one of the ammunition transporters. Each ammunition transfer arm is pivotal about the trunnion and includes a lifting arm having third holders for picking up and lifting a projectile or propelling charge column. Two readiness trays are arranged, one on each side of the loading tray, for receiving either a projectile or propelling charge column from one of the ammunition transfer arms.
