Definitions

the invention relates to a penetrator for sub-caliber balancing projectiles with a length-to-diameter ratio of Der 20.
penetrators which are used in so-called arrow projectiles, are fired with a caliber-compensating sleeve or a sabot which is removed from the penetrator immediately after leaving the tube solves.
Arrow projectiles are characterized by a large length-diameter ratio and can be made, for example, from depleted uranium, sintered heavy metals and their alloys in order to ensure a high weight, so that a high penetration rate can be achieved.
Penetrators of the type mentioned at the outset are used in particular as armor-piercing projectiles and, above all, are chosen for the bombardment of multiply armored objects.
the choice of particularly heavy materials with a high specific weight serves to increase the penetration force, whereby correspondingly heavy materials usually require a material with a relatively high brittleness.
the outer surface of such penetrators must be carefully processed and smooth.
retaining ribs for the sabot must be provided on the outer surface, which adversely affect the ballistics.
the penetrator according to the invention essentially consists in that a section tapering in relation to the tip to the axis of the penetrator is arranged in the axial direction next to the penetrator tip and that the center of gravity of the penetrator lies in front of the longitudinal center of the penetrator in the direction of the tip. Characterized in that a tapered section is then arranged on the penetrator tip, the ground suction is significantly reduced during the flight and at the same time the weight is shifted forward, thereby increasing the shot and hit precision.
the tapered section offers the additional advantage that the sabot with a small number of retaining ribs on the Can attack the outside of the penetrator, since the sabot runs up and is held at the section that widens towards the tip and tapers towards the rear.
the reduction in the number of retaining ribs which in extreme cases can lead to the complete omission of retaining ribs, likewise leads to a significant improvement in the outer ballistics.
the design according to the invention is advantageously made such that the ratio of the largest diameter to the smallest diameter of the tapered section multiplied by the length of the tapered part is chosen between 50 and 300, with such a design having shown that a particularly high one Shooting and hit precision can be achieved. Furthermore, shooting tests have shown that the conical shape of the front part of the penetrator results in increased penetration. This can be explained by the fact that as the penetration into the target material progresses, the cross section of the penetrator is successively reduced, which ultimately reduces the resistance to penetration and leads to increased overall penetration.
the tapering section can be designed conically with straight generatrices.
a penetrator is partially indicated in section in a tube.
the gun barrel is designated 1 here.
the penetrator 2 has a tip 3 and a conically tapering section 4 adjoining the tip 3.
the taper goes from an outside diameter D 1 following the tip 3 to an outside diameter D 2, which corresponds to the smallest cross section of the tapering section.
the axial length L1 of this tapered section is so hit that the ratio is set between 50 and 300.
This tapering section 4 is followed by a further section 5 of the penetrator, on the outer circumference of which, for the transmission of the acceleration forces to the penetrator, holding grooves or a thread can be provided.
the sabot engages on this section 5, which is of essentially constant outside diameter, and is designated by 6.
the sabot 6 is guided in the gun barrel 1.
a tail unit 7 is indicated at the rear of the penetrator 2.
the acceleration forces which are to be transmitted from the drive cage 6 to the penetrator 2 act not only on the holding ribs or grooves of the section 5, but also on the section 4 which widens conically towards the tip, so that due to the force transmission in the area of the tapered section 4, the number of retaining ribs in the following section 5 can be significantly reduced.
