Projectile

Abstract

Projectile for a small arms weapon having a barrel. The projectile comprises a projectile body; a plurality of external peripheral fins; a coupling for each fin to mount the fin to the projectile body to enable pivotal movement of the fin from an un-deployed position to a deployed position and to enable displacement of the fin in a radial direction of the projectile body; and means to bias displacement of the fin in the radial direction.

1 . A projectile for a small arms weapon having a barrel, said projectile comprising:—
 a projectile body; 
 a plurality of external peripheral fins; 
 a coupling for each fin to mount the fin to the projectile body to enable pivotal movement of the fin from an un-deployed position to a deployed position and to enable displacement of the fin in a radial direction of the projectile body; and 
 means to bias displacement of the fin in the radial direction. 
 
     
     
         2 . The projectile according to  claim 1  wherein said coupling comprises:—
 channel means formed in said fin to be aligned with the axis of said projectile and having a slot shaped cross section with a longer axis facing towards said radial direction; and 
 pin means mounted to the projectile body to locate with said channel means to provide said pivotal movement of the fin. 
 
     
     
         3 . The projectile according to  claim 2  wherein said channel means extends along the entire length of the fin in the direction of said axis of the projectile. 
     
     
         4 . The projectile according to  claim 3  wherein the pin means comprises a single pin extending along the entire length of the fin in the direction of said axis of the projectile. 
     
     
         5 . The projectile according to  claim 2  wherein the pin means comprises a pair of pins, each extending into an opposing end of said channel means. 
     
     
         6 . The projectile according to  claim 1  wherein said coupling comprises:—
 pin means extending from either end of the fin in the direction of said axis of the projectile; and 
 
       channel means formed in said projectile body to be aligned with the axis of said projectile and receiving said pin means fin, wherein the channel means has a slot shaped cross section with a longer axis facing towards said radial direction.
