Estimating the term…
A subcaliber projectile including a segmented discardable propelling cage sabot which encloses at least a portion of the projectile body and has a common form-locking zone for the transfer of acceleration forces from the propelling cage to the projectile body. The form-locking zone has mating annular grooves and counter grooves on the exterior surface of the projectile body and on the interior surface of the propelling cage, and is subdivided into several form-locking zone regions in which the annular grooves have a different groove spacing that is adapted to the locally occurring shear stresses. These measures enhance simplification of the manufacturing process and result in an improvement of the release of the propelling cage sabot from the projectile body and in an increase in the target impact velocity of the projectile body.
In a projectile arrangement including a subcalibar projectile having a projectile body, a segmented discardable propelling cage sabot which surrounds at least a partial region of the length of said projectile body, and form locking means, disposed in a common form-locking zone extending along at least a portion of said region of said projectile body, for transferring acceleration forces from said propelling cage sabot to said projectile body, with said form-locking means including corresponding annular grooves on an exterior surface of said projectile body and on an interior surface of said propelling cage sabot;
