Training Projectile and Training Cartridge

Abstract

The invention relates to a training projectile ( 1 ) for short-range use, in particular less than 100 meters, comprising a front region ( 2 ), which extends along a central axis (M) and which comprises a projectile tip ( 3 ), and comprising a tail region ( 4 ), which adjoins the front region ( 2 ) in the direction of the central axis (M) and which comprises a projectile end ( 5 ). The tail region ( 4 ) is designed for receiving the projectile ( 1 ) in a cartridge case ( 6 ). The projectile ( 1 ) comprises a projectile core ( 7 ) made of metal and a jacket ( 8 ) which surrounds the projectile core ( 7 ), determines the outer shape of the projectile ( 1 ), and is made of plastics.

 or wherein the retaining segment is bounded by two elevations surrounding the projectile and extending outwards from a diameter of the tail region;   or wherein the retaining segment is bounded by one elevation surrounding the projectile and extending outwards from the diameter of the tail region.   
     
     
         27 . The training projectile as claimed in  claim 20 , wherein the projectile core, when viewed in a firing direction along the central axis, is disposed in the front region of the projectile, or wherein the projectile core, when viewed in the firing direction along the central axis, is disposed centrally between the tip of the projectile and the end of the projectile. 
     
     
         28 . The training projectile as claimed in  claim 20 , wherein the projectile core has a length in a firing direction that is smaller by a factor in the range from 2 to 5, than the total length of the projectile from the tip of the projectile to the end of the projectile when viewed in the direction of the central axis and/or wherein the projectile core has a diameter that is smaller by a factor in the range from 1.1 to 1.8 than the nominal diameter of the projectile. 
     
     
         29 . The training projectile as claimed in  claim 20 , wherein the projectile core is made of a metal, such as steel or a non-ferrous metal, or of a metal alloy with steel and/or non-ferrous metals, and wherein the jacket is made of a plastic, especially of an elastomer or thermoplastic, or of a plastic mixture, especially of elastomers and/or thermoplastics. 
     
     
         30 . The training projectile as claimed in  claim 20 , wherein the projectile has a larger diameter in segments than a defined nominal diameter of the projectile, wherein the diameter is particularly preferably greater by a factor in the range from 1.05 to 1.1 than the nominal diameter. 
     
     
         31 . A training cartridge comprising a projectile as claimed in  claim 20  and a cartridge case, wherein the cartridge case comprises a casing part and a base of the cartridge joined to the casing part, wherein at least the casing part is made of plastic and wherein the projectile is retained in an accommodating segment in the casing part by means of positive locking, non-positive locking, and/or bonding. 
     
     
         32 . The training cartridge as claimed in  claim 31 , wherein the base of the cartridge is retained in the casing part by means of positive locking, bonding, and/or non-positive locking, and/or wherein the base of the cartridge is made of metal and/or plastic and the receptacle acts as an ignition cap. 
     
     
         33 . The training cartridge as claimed in  claim 31 , wherein the accommodating segment in which the projectile is retained has an internal diameter that is smaller than the external diameter of the projectile in a vicinity of the tail region, which is disposed in said accommodating segment. 
     
     
         34 . The training cartridge as claimed in  claim 31 , wherein at least one of said elevations, when viewed in a firing direction, is disposed after the accommodating segment in the cartridge case, wherein said elevation has a diameter that is larger than an internal diameter of the accommodating segment. 
     
     
         35 . The training cartridge as claimed in  claim 31 , wherein the accommodating segment, when viewed in a firing direction, has a length along the central axis that corresponds to a length of the retaining segment.
