Description

ladung von dieser und den Zentrieransätzen auf der Innenseite und von dem ringförmigen Mittelteil auf der Außenseite eingeschlossene Hohlraumteil dient Aufgaben, die im wesentlichen denjenigen der Kanäle 9 entsprechen.charge from this and the centering lugs on the inside and from the annular central part the cavity part enclosed on the outside serves tasks that essentially correspond to those of the channels 9 correspond.

F i g. 5 zeigt eine weitere zweiteilige Ausführungsform als Längsschnitt V-V gemäß F i g. 5 a, bei der die Bohrungen und Kanäle — mit Ausnahme der in ihren Ansätzen noch vorhandenen Kanäle 9 in den Endbereichen des Pulverkörpers 1 — durch sich aus der Formgebung der Preßteile ergebende Hohlräume 11 ersetzt sind. In Fig. 5a ist ein Schnitt Va-Va gemäß F i g. 5 dargestellt.F i g. 5 shows a further two-part embodiment as a longitudinal section V-V according to FIG. 5 a, at the the holes and channels - with the exception of the channels 9 still present in their approaches in the End regions of the powder body 1 - by cavities resulting from the shaping of the pressed parts 11 are replaced. FIG. 5a shows a section Va-Va according to FIG. 5 shown.

F i g. 6 zeigt schließlich einen Pulverkörper 1, der mit einem Zündmittel 3, das im vorliegenden Beispiel als Zündstab ausgebildet ist, sowie einer Beiladung 6 unmittelbar verpreßt ist. Zündstab und Beiladung sind über einen Kanal 8 miteinander verbunden.F i g. 6 finally shows a powder body 1 which is provided with an ignition means 3, which in the present example is designed as an ignition rod, and a supplementary charge 6 is pressed directly. Ignition rod and additional charge are connected to each other via a channel 8.

Alle aufgeführten Pulverkörper weisen eine rotationssymmetrische Zylinderform auf. Generell sind jedoch alle Querschnitte möglich, bei denen das Geschoß nicht mit dem Pulverkörper verbunden zu sein braucht. Auch Pulverkörper mit nicht einheitlich ausgebildetem Querschnitt sind denkbar.
Sämtliche erwähnte Ausführungsformen können inAll the powder bodies listed have a rotationally symmetrical cylindrical shape. In general, however, all cross-sections are possible in which the projectile does not need to be connected to the powder body. Powder bodies with a non-uniform cross-section are also conceivable.
All of the mentioned embodiments can be used in

ίο nicht dargestellter Weise mit einem beim Schießvorgang verbrennenden oder verdampfenden Oberflächenschutz — beispielsweise einer Zinn-Blei-Kombination, einer Metall-Kunststoff-Kombination oder ähnlichen Kombinationen — ausgestattet sein, wobei ein Luftpolster zwischen Hülle und Körper aus Isoliergründen zweckmäßig ist.ίο in a manner not shown with a shooting process burning or vaporizing surface protection - for example a tin-lead combination, a metal-plastic combination or similar combinations - be equipped, where an air cushion between the cover and the body is useful for reasons of insulation.

Claims

for a projectile, as with a patent claim in caliber: effect comparable, conventional case ammunition. In addition, the powder charge should be as low as possible

Powder bodies for caseless ammunition can be arranged for a small space.
This object is achieved according to the invention by borrowing small-caliber weapons, which consists of a charge which is formed as an oxygen and calorie use of binders, which is pressed into a bore consists and is provided with an ignition and / or in a recess of at least one additional charge made of powder types, consisting of different grain sizes, characterized by the fact that the channels charge (6) running axially to the axis of the powder body are rich in oxygen and calories La- provided powder body is stored, and that the manure is formed in a bore (5) igniting charge which is arranged in recesses of at least one or in a recess (S, 11) of the powder end face of the powder body through different grain sizes exist- channels connected to the additional charge.
the powder body (1) provided with ducts (8) extending coaxially to the powder body axis are described below with reference to FIGS. 1 to 6. It is stored and that the squib (3) that shows in

Recesses (2) of at least one end face F i g. 1, for example, from several powder

The invention relates to a powder body for cover film 4 secured against falling out. In a primarily small-caliber weapon 30, which is provided at the caseless ammunition for use with the automatically opposite end, is located, also loosely inserted, a ring that is made up of a charge 6, which is held by a film 7 against Falling out means pressed propellant charge and is secured with a. The bore 5 and the Ausneh-Zünd- and at least one additional charge is provided. tion 2 are connected to one another by ignition channels 8. A sleeveless propellant is connected with solid propellants. Other concentrically arranged channels 9, bound projectile known (DT-PS 4 55 382). At 35, which protrudes into the interior of the powder from both end faces in one with the projectile body through body 1, a propellant connected in particular for crimping results in an ignition charge and a configuration favorable for combustion,

It is also known in the case of caseless ammunition by means of 3 versions that differ from FIG. 1 (US-PS 33 45 945, GB-PS 11 62 158), in an approximate form and Fig. 2a shows a section Ha-IIa according to continuous axial bore of a powder jacket F i g.

Finally, it is designed in the case of a conventional sleeve Hch and, if necessary, the additional charge 6 cartridge became known (DT-AS 17 28 237), in the record. The Ka propellant charge space arranged in both halves the sleeve alternating sections 55 channels 8 and 9 are congruent, with for the fitted with propellant powder and oxidizer powder prior to mutual assignment in the channels 8 see.

The invention is based on the object, designed for blind holes and running from the against an automatically shooting, primarily small soapy support points in the direction of the end faces,

The powder body should be present in the parts. On the one hand, the latter have the strength to be able to slide the mechanical centering projection 10 into the recess 11 of the annular stresses in the closure in the case of the Zu-shaped central part. When loading and ejecting failures in the weapon, the central area of the recess must be kept between the centering stand, and on the other hand, an equally short approach to a cavity suitable for the reception of a supplementary charge 6 shot development time and muzzle velocity.
