초록

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 substan...
