Abstract

Proposed is a caseless ammunition (1, 10) with a projectile (2) which is surrounded by a combustible sleeve (3, 13), the projectile (2) at the rear a cavity (4, 14) for receiving an additional charge (6 , 16). The cavity (4, 14) itself opens into a nozzle-like extension (5, 15). This ensures that the projectile (2) in good time to the gun barrel (25) nibbling before the combustible sleeve (3, 13) the bullet (2) releases.

Description

A caseless ammunition is usually used for recoilless or recoil arms needed, the a nozzle-like extension at the rear end of weapons. Such ammunitions are characterized from that the bullet enclosed by a combustible sleeve becomes.

A caseless ammunition with a bullet describes the DE 102 37 707 B4 , Other versions of the caseless ammunition are the DE 10 2005 026 976 B4 , of the DE 10 2005 020 669 A1 or the DE 10 2005 012 284 A1 removable. A powder body for a caseless ammunition describes the DE 10 2004 039 761 B4 ,

While the normal ammunition or a cartridge case the bullet so wears that bullet tip already in the gun barrel is the problem with a caseless ammunition in that the bullet of the ammunition located in the chamber must first beak at the gun barrel.

The Invention sets itself the task, in particular the Anschnäbelvorgang support such that the projectile in straight line the gun barrel is pushed into it.

Solved The object is achieved by the features of claim 1. Advantageous Embodiments are shown in the subclaims.

Of the Invention is based on the idea, the projectile on the rear side a Incorporate additional charge, with which the projectile independently and before complete combustion of the combustible sleeve / sheath is accelerated into the barrel. The sleeve is used as a bullet guide, so to speak.

rear- the projectile has a cavity with a nozzle-like Expand to. The additional charge is preferably ignited inductive. This will be before the sleeve releases the bullet and no longer encloses, a deliberate pushing of the projectile into the weapon barrel. With the beam of inductive Igniting the additional charge, the sleeve is ignited. Since the bullet is already geschnäbelt in the barrel, drives the pressure of the propellant or of the reacting gas the projectile through the barrel.

These it is a projectile with short sleeve, the secondary coil can in the basement floor directly from the primary coil on / in the chamber be initiated. On projectiles with a longer sleeve offers the integration of another coil in the chamber or within the sleeve body, which coincides with the Secondary coil in the rear part of the projectile works together.

Of the Advantage of this solution lies in the fact that possible Residual coil parts transported with the projectile from the weapon barrel become. Due to the time delay between bullet drive into the barrel and the bullet passage through the barrel a tilting while biting is avoided.

Based an embodiment with drawing, the invention be explained in more detail. It shows:

1 a short caseless ammunition with projectile in a partial sectional view,

2 a longer caseless ammunition with projectile in a partial sectional view,

3 a drum weapon with the ammunition 2 in a sectional view.

In 1 is a first caseless ammo 1 with a bullet 2 and a combustible shell or sleeve 3 shown. Rear side has the bullet 2 a cavity 4 with a so-called nozzle extension 5 back on. In this cavity 4 introduced is an additional charge 6 to accelerate the projectile 2 inside the combustible sleeve 3 for better nibbling the bullet 2 on or in a weapon barrel 25 , as in 3 shown in more detail. The additional charge 6 may be a conventional propellant. Rear side is a bullet own inductance 7 involved in igniting the additional charge 6 serves.

2 shows another caseless ammo 10 , with a bullet 2 , a sleeve 13 a cavity 14 with a nozzle extension 15 and a bullet-side inductive detonator 16 ,

Is the distance between the bullet-side detonator 16 and a weapon-side ignition 26 ( 3 ) Too large to make a direct ignition should be in the cartridge chamber 22 an ignition transmission 27 (eg cable with coil). About this can then ignite the ignition of an additional charge 16 will be realized. An alternative is the inclusion of a Zündübertragung 18 in the sleeve 3 ( 2 ).

3 shows a use of caseless ammunition 10 in a recoilless or low recoil weapon 20 here for example as a drum weapon with a Laval nozzle 21 is executed and several cartridges 22 in a drum 23 has. The chamber 22 act with the weapons own nozzle extension 24 together.

The ammunition 1 gets from the front into one of the cartridge chamber 22 pushed and by a turn the drum 23 in front of the barrel 25 brought into the firing position. As with caseless ammunition 1 . 10 known, the required drive energy for the projectile 2 by burning off the sleeve 3 generated after initiation of the burnup.

To ensure safe insertion of the projectile 2 in the barrel 25 to achieve, is only the additional charge 6 inductively ignited. The propagating beam of this ignition then initiates burnup of the sleeve 3 , The bullet possesses this 2 an inductance on the rear side 17 ( 7 ) with the weapon-side primary inductance 26 interacts functionally. The projectile passes through the initial ignition of the additional charge 2 single-mindedly in the weapon barrel 25 , the subsequent gases of the burned sleeve 13 push the bullet 2 then through the barrel 25 in a known manner.

In a preferred embodiment, the inner shape of the combustible sleeve 3 the longer ammunition 10 on the extension 15 of the cavity 14 tuned and also slightly widening. This has the advantage that the jet of the inflating additional charge 16 expanding outward the sleeve 13 can light continuously.
