the projectile and casing assembly with liberal in the propellant

摘要

A detachable connection between a projectile and a propellant-charge case for cartridge-encased ammunition adapted to be fired from a gun barrel. The propellant-charge case is provided at the front end zone with at least one recess receiving a locking element radially displaceable between inner and outer end positions. The element in the outer end position projects outwardly of the propellant-charge case to an extent sufficient to prevent complete introduction of the propellant-charge case into the gun barrel and is supported in this position by a movable blocking member which is displaceable against the force of a spring toward the rear of the propellant-charge case. The projectile which is to be connected with the propellant-charge case is provided with a tail portion arranged for contacting the blocking member and to displace the blocking member toward the rear. The tail portion is also provided with a recess adapted to be engaged by the locking element upon displacement of the blocking member such that the locking element assumes the inner end position connecting the projectile and the propellant charge case and permitting introduction of the flush connection of the projectile and the propellant-charge case into the gun barrel for support therein.
