Hare-charge warhead

The »invention relates to a hollow head,

BohlX load warheads are in a raannig-fold design known. The aim was always to achieve maximum penetration for a given caliber achieve for what purpose, for example, the opening ^ angle of the shaped charge lining was varied, different Ferns of the lining have been examined and the like. A design has proven to be the standard format result in the sinter of the circular conical foral gene Lining the main charge is arranged and the initiation is optimized by the fact that the transfer charge from the detonator to the main charge adjoins the main charge. Therefore it is an inert filler envisaged a corresponding delay the detonation in the axis string caused "

In general, the propellant charge for hollow charge projectiles can be used so I had no trouble whatsoever prepares the for the desired high throughput required amount of explosives in de »Storey to be provided, other conditions apply *

however, if you consider the overall dimensions bzvi, the total weight of the bullet also has restrictions is subject to, for example at Kale e t enmimi t i on.

The object of the invention is to provide a shaped charge warhead of the type mentioned at the outset to create a maximum of penetration performance with a minimum weight owns, in other words; The shaped charge warhead should be designed so that for a given caliber, the best efficiency with regard to Durchschlagslei stung / weight is achieved.

This task is performed with a shaped charge warhead with conical shaped charge lining of the cone angle so-called and a base circle of diameter D and a jacket thickness d, behind which and uni the heruai a main charge of the outer diameter D is arranged, and with one arranged at a distance h behind the liner tip and an inert material insert in spherical zone shape surrounded by a transfer charge, the flat surface of which with the radius r facing the liner tip, solved by the design rule:

. O ₀ = 60..75 °

h = 0.2, .0.33 D.
d _s 0.010..0.017 D h / r α tan

The rule according to the invention is based on the following Considerations;

For a given cone angle, the stroke decreases power with the distance between the liner tip

and inert material initially increased considerably, but slowed down the increase in the breakdown power increases if the main charge continues to increase to the same extent will. On the other hand, the weight of the warhead is reduced it with increasing main charge record ruler * to, see above that eventually a point will be reached at which the the optimum ratio for the caliber is achieved. the so determined amount of explosives of. The main charge in turn requires a correspondingly adapted jacket thickness Lining to optimize punch through performance.

With the data for the lining and the main load it can be seen that the surprising trots in the specified manner low main charge a maximum ratio of penetration power to weight of the warhead it is achieved.

A further optimization results in sieilij albeit the composition the main charge is adapted to the shape of the same. Here has a somewhat unusual composition Proven to be superior, consisting of 10. "20 weight- ^ trinitrotoluene and 90." 80 weight-? " Hexogen or Octogen, with the best results being 15 weight Trinitrotoluene and 85 Gev: iehts- & Hexogen or Octogen achieved became.

To ignite the warhead, there is a projectile tip in it in the usual TJeise a contact device installed, the by means of a line Kit dea close to the floor Detonator is connected.

If the charge envelope is made of a high-strength magnosine alloy is gofer-tigt, daa total weight is cheap Decomposition jieigeiisehaiten much lower.

The invention is intended below with reference to the exemplary embodiment shown in the accompanying drawing are explained in more detail.

The shaped charge warhead, the schematic in the drawing ± ia partial longitudinal section is shown, comprises a sleeve 10, from a high strength magnesium alloy, on the rear part of the individual is not screwed iia illustrated igniter 12th In front of the igniter 12 there is a transfer charge Ik, for example made of phlegmatized hexogen, which is marginally in initiation connection with a main charge 16, "while it is shielded in the middle by an inert material insert 18 made of plastic against the main charge 1-6, which is made of trinitrotoluene (± 5 %) and hexogen ($ 85). The main charge 16 surrounds, in a manner known per se, the hollow charge lining 20 made of copper or another metal. Contact device which is connected to the detonator 12 via a line 15 laid in a breakthrough in the main charge.

The base circle diameter i * D of the liner, which is here is almost identical to the bullet caliber, is the gauge for the distance h between the liner tip 'and the flat surface of the inert material insert. In the exemplary embodiment is h = 0.216 D according to the LeJu-e der Invention.

The base circle diameter i 'D is also the reference dimension for the jacket thickness d of the liner; im Ausfülirungsl> eii; picl. According to the drawing 1st d = 0.016 D (the drawing is here, for the sake of clarity, not entirely in scale).

The tip angle OC of the conical outer clothing is 67.5 °; this implies tan 33 ° = 0.666. The ratio acc distance h to the radius r of the inert material insert, on the other hand, is 0.727 and is thus - according to the teaching of the invention - somewhat greater than the tangent of half the apex angle.
