Abstract
A novel rifling is disclosed, wherein a plurality of arc segments are disposed equally about the bore of a gun barrel, when viewed in cross-section. The surface of each arc segment comprises a bearing surface that imparts a spin on a projectile moving down a length of the gun barrel.
Claims20
A gun barrel having circumferential rifling, comprising:
- a bore of the gun barrel, the bore having an equal diameter as a circumference of a projectile for the gun barrel, at the largest dimension of the diameter of the bore;
- a first plurality of equal length arc segments equally distributed around the bore of the gun barrel as viewed in cross-section, wherein each arc segment of the first plurality of equal length arc segments has a same radius;
- and
- a second plurality of equal length stop segments as viewed in cross-section, joining the second end of each arc segment to the first end of an adjacent arc segment at an obtuse angle, each stop segment having a length that is a small fraction of a length of each of the equal length arc segments,
- wherein the first plurality of equal length arc segments and the second plurality of equal length stop segments are helically disposed within the bore over a length of the gun barrel.

- a first plurality of equal length arc segments equally distributed around the bore of the gun barrel as viewed in cross-section, wherein each arc segment of the first plurality of equal length arc segments has a same radius;
- and
- a second plurality of equal length contact zones as viewed in cross-section, each contact zone formed by joining the second end of each arc segment to the first end of an adjacent arc segment at a 180° angle,
- wherein the first plurality of equal length arc segments and the second plurality of equal length contact zones are helically disposed within the bore over a length of the gun barrel.
