Benefits of technology

[0010]This separation of the sabot from the projectile body takes place almost without any mechanical interaction between the sabot and the projectile body and, thus, minimizes a departure impairment.

Problems solved by technology

The disadvantage of the known sabots, i.a., is that at the separation of the sabot from the projectile body, a mechanical influencing of the projectile body frequently takes place, so that the departure of the projectile body is impaired.
In both cases, this may cause the projectile body to wobble, which must be compensated for during the further flight of the respective projectile body, for instance, through a compensating twist.

Embodiment Construction

[0019]In FIG. 1, 1 designates a barrel of a smoothbore weapon (e.g., a mortar) in which a projectile unit 2 is situated that, after ignition of a propelling charge (not shown), moves towards the muzzle 4 of the barrel 1 due to the high-pressure propelling charge gases 3 produced by igniting the propelling charge. The projectile unit 2 is composed of a full-caliber projectile body 5 and a plate-shaped sabot 6, which, according to the invention, is made of an aluminum alloy, and the sabot is arranged at the rear of the projectile body 5 and, likewise, has an outer diameter that corresponds to the caliber of the barrel 1.

[0020]The projectile body 5 shown is not a hostile projectile, but, for example, is the assembly of a rocket whose firing strength is to be tested. The projectile body 5 is hereby shown simplified only as a solid body. However, it can, of course, also be a hollow body, for example, to accept control electronics, fuel or propelling charge powder, etc.

Abstract

A disk-shaped sabot is provided for accelerating a projectile body fired from a smoothbore barrel, the projectile body having the same caliber as the barrel. The sabot is configured so that it is supported only in sections on the rear zone of the projectile body to transmit gas pressure forces impacting the projectile body, at least one cavity remaining between the sabot and the rear of the projectile body. At least one pressure-relieving bore extends through the bottom of the sabot, through which bore propelling gases penetrate the cavity when the projectile unit is fired and produces a defined excess pressure in relation to the outer ambient pressure, which causes the sabot to separate from the projectile body as soon as the projectile unit, consisting of the projectile body and the sabot, passes the muzzle of the barrel and without impairing the further trajectory of the projectile body.

Description

[0001]This is a National Phase Application in the United States of International Patent Application No. PCT / EP2008 / 005246 filed Jun. 27, 2008, which claims priority on German Patent Application No. DE 10 2007 033 833.5, filed Jul. 18, 2007. The entire disclosures of the above patent applications are hereby incorporated by reference.FIELD OF THE INVENTION[0002]The invention relates to a disk-shaped sabot for accelerating a projectile body that can be fired from a launch tube embodied as a smoothbore barrel, wherein the projectile body preferably has the same caliber as the barrel.BACKGROUND OF THE INVENTION[0003]The use of disk-shaped sabots for armor projectiles were known from the Rheinmetall GmbH, Düsseldorf document “Waffentechnisches Taschenbuch” [Weapons Manual], 7th edition 1985, page 472 ff. The aim of these known sabots is to achieve a high initial velocity when a projectile embodied sub-caliber is fired and to have, during the further trajectory, a low deceleration. The sab...
