Abstract
A high pressure obturator for a breech loaded, tube-launched projectile includes a generally annular ring having a central longitudinal axis and a radially inward portion. A flange portion is disposed radially outward of and partially contiguous with the radially inward portion. The flange portion extends axially forward and aft beyond the radially inward portion. The outer diameter of the flange portion decreases linearly from an aft most outer diameter to a forward most outer diameter. The obturator may be formed of a plastic material and include circumferential wraps of a high-strength fiber completely embedded in grooves in the obturator.
