Barricade-penetrator

Abstract

A projectile with a penetrator, which on impact with an obstacle (wall, door, glass pane etc.) pierces it, so that immediately afterwards an active substance which is carried along by the penetrator, is set free behind said obstacle. Such a projectile is of particular use by special police, military or other operations as a so called barricade-penetrator, in order to set out of action persons to be overpowered in closed rooms. The release of the active substance occurs without a pyrotechnic detonation; the active substance is expelled exclusively through mechanical means, and preferably by a piston action resulting when the projectile contacts the obstacle.

We claim:  
     
         1 . A projectile with a penetrator centrally arranged in a projectile body to pierce an obstacle on impact of the projectile with the obstacle, characterized in that the penetrator includes an active substance and a piston, said piston carrying the active substance through a hole in the obstacle formed by said penetrator.  
     
     
         2 . The projectile according to  claim 1 , characterized in that the projectile body includes a projectile jacket having a hollow cylinder in which the piston is located, the active substance being stored between a coneshaped tip of the penetrator and the piston.  
     
     
         3 . The projectile according to  claim 1 , characterized in that the projectile body includes a projectile jacket having a hollow cylinder, the penetrator includes a penetrator tip closing off a forward open end of the hollow cylinder and a shaft within the hollow cylinder carrying at a free end the piston in the form of a disk axially movable along the cylinder, and that a hollow space formed between the tip and the piston contains a reservoir for the active substance.  
     
     
         4 . The projectile according to  claim 3 , characterized in that the hollow cylinder is formed in two parts.  
     
     
         5 . The projectile according to  claim 4 , characterized in that the hollow cylinder has a front part and a rear part, both parts being connected to each other, the front part extending rearwardly to at least the piston and overlapping the rear part on the inner side of the rear part.  
     
     
         6 . The projectile according to  claim 2 , characterized in that the cylinder has a flange which extends peripherally at a front end of the cylinder.  
     
     
         7 . The projectile according to  claim 3 ,  4  or  5  characterized in that the tip is covered by a thin-walled cap which is positively supported by the projectile jacket.  
     
     
         8 . The projectile according to  claim 2  or  3 , characterized in that the active substance is contained in an easily destructible wrapping.  
     
     
         9 . The projectile according to  claim 2  or  3 , further including a projectile base contains a bursting charge for the projectile.  
     
     
         10 . The projectile according to  claim 9 , further includes that the bursting charge comprises a percussion fuse, an ignition chain and a propelling charge with gas outlets, wherein the gas outlets are actively connected to a pressure chamber and let gas pressure impinge against the projectile jacket.
