Abstract
To improve the terminal ballistic performance of a subcaliber projectile 15 composed of a penetrator 15b and a tail guide assembly 16, a partial region 15a of the projectile 15 is given a conical configuration and is seated in a likewise conically configured recess 16a of the guide assembly 16. Thus, the transverse forces exerted on the guide assembly 16 during penetration of the target material are prevented, at least in the conically configured region 15a of the guide assembly, from being transferred to the penetrator 15b so that the penetrator 15b is prevented from breaking in this region.
Claims11
A fin-stabilized subcaliber projectile, comprising:
- an elongated kinetic energy penetrator having a cylindrical surface for most of its length and having a high ratio of length to diameter, the penetrator additionally having a tail end and a rear region with a conically configured surface adjacent the tail end, the conically configured surface having a cone angle .alpha., the penetrator additionally having a cylindrical pin with an external thread at the tail end;
- and
- a rear guide assembly having a recess with a conically configured surface, the conically configured surface of the recess having a cone angle .beta. which is larger than .alpha., the guide assembly additionally having an internally threaded bore which communicates with the recess, the pin of the penetrator engaging the bore to breakably attach the guide assembly to the penetrator, wherein the rear region of the penetrator extends into the recess of the guide assembly and the conically configured surfaces are spaced apart.
A subcaliber projectile, comprising:
- an elongated penetrator having a tail end with a threaded pin, the penetrator additionally having a region with a tapered surface adjacent the threaded pin and a fracture zone between the pin and the region with the tapered surface;
- and
- a guide assembly which includes a central member and stabilizing fins which extend from the central member, the central member having a recess with a surface and having a threaded bore centrally disposed in the recess, the pin being screwed into the bore and the tapered surface of the penetrator being spaced apart from the surface of the recess in the central member of the guide assembly.
