ABSTRACT:
To serve a turret-mounted tank cannon, automated loading apparatus includes a pair of arcuate guide tracks vertically mounted to the turret. The guide tracks, lying on radii centered with the cannon elevating axis, guide a trolley for movement between magazine and cannon loading postions. A rammer, carried by the trolley, is activated to retrieve an ammunition round from magazine storage and to ram the round into the cannon breech regardless of cannon position in elevation and azimuth. The trolley is propelled by a ballscrew, while the rammer is activated by a ballscrew and stiff-backed chain arrangement to achieve an extra long rammer stroke. The rammer is pivotally mounted to the trolley for movement between essentially opposite end-for-end orientations to permit round retrieval from ammunition magazines located in the turret bustle and tank hull, as well as in the turret basket.
