Definitions
- the invention relates to a method for producing a steel jacket and a Heavy metal core existing shell penetrator.
- the invention has for its object a simple and inexpensive method specify for the manufacture of a jacket penetrator, the structure of the heavy metal core and / or its sensitivity to fracture is not or not significantly influenced.
- the invention is essentially based on the idea that the steel jacket initially then heat a temperature between 70 and 350 ° C, preferably to 150 ° C the heavy metal core with a smooth surface in the heated steel jacket bring and finally cool the steel jacket, so that after the Shrinkage process results in a press fit.
- the steel jacket and the Heavy metal core can also be glued together.
- the sensitivity to breakage is reduced of the heavy metal core significantly reduced by reducing the notch effect.
- the jacket penetrator produced by the method according to the invention can advantageously can be easily disassembled later. For this, the jacket of the penetrator warmed up again and after appropriate expansion of the heavy metal core removed so that the individual parts can be used differently. In particular it is then possible to use a different penetrator in the existing jacket (Wechselpenetrator). This can be useful, for example, when Further development of the penetrator technology used accordingly improved penetrators or if, e.g. due to a changed threat situation, the penetrator serve other purposes.
- the steel jacket is produced by powder metallurgy because it is a very economical process. Because from the powder material can the production geometry practically in one step without subsequent mechanical treatment. One is also special Precise coaxial position between core and jacket can be created. Such jacket penetrators therefore have a particularly trouble-free and shuttle-free flight phase.
- 1 denotes a schematically illustrated wing-stabilized jacket penetrator. This consists of a tungsten heavy metal core 2, a powder metallurgy manufactured steel jacket 3, which is a tubular main part 4 and a solid material existing tailgate 5 includes, on which a tail unit 6 is screwed, and one ballistic hood 7.
- the tubular main part 4 of the Steel jacket 3 to a temperature between 70 and 350 ° C, preferably of 150 ° C, heated. Then the heavy metal core 2 provided with a very smooth surface 8 introduced into the heated steel jacket 3.
- the inner diameter of the steel jacket 3 and the outer diameter of the heavy metal core 2 one in the weft direction have a slightly opening conical shape.
- the steel jacket 3 is then cooled, so that it onto the heavy metal core 2 shrinks.
- the inner diameter of the steel jacket 3 and the outer diameter of the heavy metal core 2 selected such that after the cooling process sufficiently high force and positive connection between the steel jacket 3 and the Heavy metal core 2 results.
- the tail unit 6 is attached to the rear part 5 of the steel jacket 3 and the Ballistic hood 7 with its inner surface 9 resting against the projectile body, e.g. by means of Adhesive or connected by friction welding.
- the invention is of course not based on the embodiment described above limited.
- a tip is incorporated on which the ballistic hood as with monolithic Penetrators according to the prior art is applied conventionally.
