DE1703747A1 - Ammunition with tank shell - Google Patents

Description

The priority of the Luxembourg patent application Mr. 54.097 of July 13, 1967 has been used.

The invention "relates to ammunition with

Tank shell, and z-v / ar in particular, though not exclusively, Small caliber ammunition, especially with a caliber between 20 and 50 mm.

In particular, it aims to provide such a

To train ammunition so that they better than before the various Requirements of the practice corresponds, for which in particular their tank grenade in a very simple manner with a Auxiliary drive device is equipped.

For this purpose, such ammunition made of a metallic material is placed in the body of the tank shell the base of a metal, in particular uranium TJ 238, which is easily oxidized and burns when heated, according to the invention axial passage formed, from the front end of the grenade to one formed at the rear end thereof Nozzle is sufficient, with ignition devices being provided, which in the initial phase of the flight of the grenade (or even within the barrel of the firing weapon) the inflammation of the inner wall of the axial passage, which from this moment on behaves like a ramjet tube and an auxiliary drive for the grenade forms.

The invention is _u explained below with reference to the drawings by way of example, the sole figure in axial section a tank shell for ammunition according to the invention illustrating the tank shell is shown in the state in which it is located before firing.

The body 1 of the tank shell consists of

a metallic material based on a metal that oxidizes easily and burns when heated.

Of the metals with this characteristic, the uranium U 238 has proven to be particularly advantageous, which forms a cheap residue of the processes for the separation of the uranium 235 from the natural uranium.

It is therefore assumed below that the

Body 1 of the shell is formed on the basis of uranium U 238, the weight content of this uranium U 238 is large than 90, and preferably fo grössenordnungamässig 95 ^a ß> is.

The material forming the body 1 of the grenade then expediently contains additives which improve the mechanical properties of the body and in particular can be tungsten and / or cobalt.

In the body 1 of the grenade thus formed

an axial passage 2 is produced, which extends from the front end of the grenade to a nozzle 3 formed at the rear end thereof, ignition devices being provided which, in the initial phase of the flight of the grenade, cause the inner wall of the axial passage 2 to be ignited, whereupon this λ continues to burn from this moment on due to the nature of the material forming the body 1 of the grenade, so that the axial passage 2 forms the combustion chamber of a ramjet tube, which is fed with combustion air at the front and ejects a propellant jet through the nozzle 3.

By simply drilling through and training

a nozzle at the rear end of the body 1 of the grenade, this is thus provided with a proper auxiliary power unit after ignition.

The ignition devices for igniting the * inner wall of the passage 2 can be designed so that their expression by the ignition of the ammunition in the case contained propellant charge takes place, wherein these ignition devices can be formed by a pyrotechnic mixture 4, soft in the vicinity of the rear end of the axial passage 2 is arranged and can be appropriately designed so that it desiüugeo the grenade a leuohtspur in the initial phase generated"

After the mixture 4 has been used up and after ignition

the inner wall of the passage 2 by the combustion of the same

becomes the one entering the passage 2 through the tip of the grafflfce Air is heated by the combustion ■ wall of the passage, and the air stream thus heated is passed through the nozzle 3 dissipated, whereby he has a drive thrust on the body 1 of the Grange exercises
