Projectile base plug with enhanced drag-producing separation capability.

摘要

A projectile base plug (10) with enhanced separation capability has a body (18) which fits into an end of a spinning projectile casing (14) and drag-producing vanes (20) being spaced apart about the circumference of the object and pivotally mounted thereto for movement between stowed and deployed positions. Upon ejection of the base plug (10) from the projectile casing (14), the vanes (20) are released from stowed positions within the aerodynamic outline of the base plug (10) where they have no substantial effect on the flight of the projectile (12), to deployed positions by centrifugal force generated by the spinning body where they project into the air stream and produce drag on the ejected base plug (10). <IMAGE>
