Abstract

A high efficiency, blow-by reducing obturator for a 105 mm tube-launched projectile is a generally annular ring having a central longitudinal axis and an outer circumferential surface. The outer surface has a first portion parallel to the central longitudinal axis and a second portion adjacent to the first portion. The second portion extends forward and radially inward at an angle of about six degrees with the central longitudinal axis. In some embodiments, one or more grooves are formed in the inner circumferential surface of the ring.
