Abstract
Improvements to a fiber optically guided projectile include an obturator with a groove formed in the outer wall. An obturator ring is placed in the groove. The ring is made of resilient material, has a relaxed diameter greater than the bottom of the groove and is split so that it is releasable from the groove. Additionally, the rear-most wall of the groove is tapered to aid in the release, and the section of the obturator forward of the groove has a larger diameter than the section aft of the groove. A curved groove acts to transition the fiber from a longitudinal to a substantially tangential direction. Furthermore, either a cone or sleeve extension is included to prevent the fiber from looping about the projectile. An ejectable aft closure plate is provided to seal the interior of the projectile during launch.
