Abstract

The process involves modifying the length of a projectile to correct the axial position of a center of an aerodynamic thrust. The modification length of the projectile in flight could be obtained by the ejection of a truncate of the projectile. The projectile has a base going up slidingly with the body of the projectile, a base with a rear part. The base is made interdependent of the body by delockable connection.
