Abstract: An obturator is provided for a projectile launched from a gun barrel. The obturator includes an annular ring that is fabricated from a high-temperature resistant composite material. The annular ring has an inner surface that is in contact with the projectile. In addition, when the projectile is fired from the gun barrel, an outer surface of the annular ring contacts an inner surface of a bore of the gun barrel. When the projectile is fired from the gun barrel, the radial distance between the inner surface and the outer surface of the annular ring substantially equals or exceeds the radial distance between an outer surface of the projectile and the inner surface of the bore of the gun barrel at at least one point. This configuration restricts a flow of charge gases from an aft end of the projectile to a forward end of the projectile as the projectile is fired from the gun barrel.
