Abstract
Official abstract text for this publication.
Embodiments of an obturator are provided herein. In some embodiments, an obturator includes an annular body having an inner surface configured to interface with a projectile, an outer surface configured to interface with a gun bore, and geometric features disposed in the annular body to create regions of localized stress and strain upon discharge from a weapon.
First claim
Opening claim text (preview).
The invention claimed is: 1. An obturator, comprising: an annular body having an inner surface configured to interface with a projectile, an outer surface configured to interface with a gun bore wherein the annular body includes a central region disposed between a leading region and a trailing region, wherein the leading region includes a first sawtooth geometry, and wherein the trailing region includes a second sawtooth geometry; and three slots extending from an outer surface of the obturator towards an inner surface of the obturator, a plurality of holes disposed within the obturator, a web defined by the inner surface and a bottom surface of said slots, said web having a thickness of 2 millimeters at its thickest portion, disposed in the annular body to create regions of localized stress and strain upon discharge from a weapon gun bore. 2. The obturator of claim 1 , wherein the first sawtooth geometry is disposed on said inner surface of the obturator, and wherein the first sawtooth geometry is configured to couple the obturator to a sabot. 3. The obturator of claim 1 , wherein the second sawtooth geometry is disposed on said inner surface of the obturator, and wherein the second sawtooth geometry is configured to couple the obturator to a cartridge case.
