Abstract
A self aligning expansible sabot for projection from worm gun tubes without alloting of the sabot pedals due to misalignment and vibration. The sabot consists of three segments pinned together so they move radially in an expanding manner in the worm gun tube without loss of axial alignment. The connection pins allow normal discard of the sabot segments without excessive binding and without independent rotation.
Claims3
A self-aligning expansible sabot projectile for use with a worn gun tube, said sabot projectile comprising:
- An elongated body having front and rear ends, a plurality of sabot segments around said body to axially align said body within said gun tube, said segments bieng held together with a front bourrelet and an obturator circumferentailly placed therearound, said sabot segments having abutting surfaces forming planes extending radially from said body outwardly, said planes extending longitudinally the length of said segments, and pins interconnecting said segments, said pins passing through said planes in a direction normal thereto, said pins having a longitudinal axis transversse to the axis of said elongated body said pins being located in cavities formed in said sabot segments, wherein said pins axially and radially align said segments while being projected through said gun tube, said segments thereafter separating from said body in flight, without any binding of the segments.
