Application of a shaped charge insert as Reflector for an antenna

The invention relates to the use of a shaped charge insert as a reflector for an antenna according to patent claim

When designed as a projectile or missile terminals with a shaped charge for fighting armored targets is the axis of the shaped charge preferably in the central longitudinal axis of the terminal in question. Should the end device be steered on its trajectory, especially in its final phase, for geometric reasons it is possible to save space Accommodation of an antenna of a transmitter and / or receiver for active, semi-active or passive Target search trained steering device of the front part of the terminal in the area of its central longitudinal axis. If the final phase control is carried out with the aid of millimeter waves, a reflector must be assigned to the antenna. Because of their arrangement, both interfere with a spike to be formed from the shaped charge insert and can thereby affect its armor-piercing effect. There, especially when firing from a barrel weapon, high acceleration forces occur, require antenna and reflector

reliable fixation of a strong bracket. By the latter can additionally impair the effect of the sting.

From DE-OS 26 12 327 a shaped charge arranged in the front part of a guided projectile is known, whose axis runs transversely to the longitudinal axis of the Gesdhosses. One for the protective housing of the concerned Shaped charge required container protrudes with its two ends over the circumferential surface of the projectile shell and leads disadvantageously to an increased air resistance. Further disadvantages resulting from the shape of the shaped charge axis result transversely to the longitudinal axis of the storey, brighten easily.

The invention is based on the object in a terminal of the type described above with a space-saving and geometrically favorable arrangement an impairment of the to avoid as much as possible the armor-piercing effect of a spike to be formed from the shaped charge insert.

This object is achieved by the invention specified in claim 1.

By not using an additional reflector a corresponding bracket is also the dead load portion of a terminal equipped with the invention reduced in an advantageous manner.

The invention is below with reference to one in the drawing in a side elevation and partially cut and in essential exemplary embodiment shown schematically and dispensing with details that are not essential to the invention explained in more detail.

A terminal device 1 designed for arrow stabilization with a central longitudinal axis L has in a head part 1 ′ a sleeve 2 of circular cylindrical cross section with an open, front end region 3. The latter is closed with a hood 4 which is attached to the shell 2 and consists of a material that is permeable to millimeter waves, which are still to be mentioned. A shaped charge insert 5 is fastened ^{with its base edge 5 1 in the end region 3 of the casing 2.} An inner surface 7 of the shaped charge insert 5 is designed to be parabolic. An antenna 6, which is only indicated, is directed against the vertex of the paraboloid surface formed by the inner surface 7, which is not designated in any more detail. The latter is connected in a manner not shown to a transmitter / receiver, which is arranged in a container behind a hollow charge 8 and is also not shown and operating in the millimeter range, for active target search. A conical part 1o adjoins the shell 2 on the rear side, which merges into a circular cylindrical tail unit carrier 11 with a stabilizing tail unit 12. In addition to the transmitter / receiver mentioned, a device for end-phase control of the terminal 1, a conventional and therefore not shown detonator for the hollow charge 8 is accommodated in the container 9.

If the terminal 1 is in its final phase on its trajectory facing a target, it becomes the transmitter / receiver turned on in a manner not described. One of the Antenna in the form of millimeter waves radiated energy is on the parabolic inner surface 7 of the shaped charge insert 5 reflected and through the hood 4 permeable to the radiation in question in the direction of one in the central longitudinal axis L lying arrow 13 emitted bundled. A portion of the beam reflected by the target passes through the opposite to the direction of the arrow 13 Hood 4 on parabolic reflector 7, becomes antenna 6 there

focussing reflected and the receiver to form a Signal for flight path correction entered.

As soon as the terminal 1 has a predetermined, effective distance from the target to be combated, for example target Has reached agitation with deformation or destruction of the hood 4 and the antenna 6, the shaped charge 8 is ignited. An armor-piercing spike formed in a known manner from the shaped charge insert 5 moves along it an extension of the central longitudinal axis L in the direction of arrow 13 and can be fully effective.
