Definitions
- the invention relates to a warhead with an explosive charge surrounding Warhead casing.
- the charges usually exist in the known Warheads made of a uniform material, which is chosen such that the Splinters generated during the detonation of the charge in a certain direction (e.g. in Flight direction) have a predetermined acceleration and angular distribution. Splinters that fly in a different direction (e.g. perpendicular to the direction of flight) become then also accelerated accordingly high, although such a high acceleration this splinter is not necessary at all.
- the invention has for its object a warhead of the aforementioned Kind of revealing that on the one hand a high acceleration upon detonation of its explosive charge the splitter flying in the direction of flight and the other causes one less acceleration of the fragments flying away to the side of the warhead caused and / or in which a relatively strong pressure wave is generated laterally.
- the invention is essentially based on the idea, not a uniform charge to be placed in the shell of the warhead, but at least two different ones To provide charges. It points in the area of the top of the warhead arranged, e.g. first partial load consisting of octogen (HMX) high Detonation speed up to the heavy metal fragments arranged in front of this partial charge (preferably WSM bullet splinters) upon detonation of the explosive charge accelerate quickly forward (in the direction of flight). On the other hand, it is the second, rear load adjoining the first partial load by one much cheaper charge (e.g. RDX charge). This partial load is only for one Acceleration of the flying away e.g. steel splinters required. Instead of a fragment accelerating charge, explosives can also be used as a second charge can be used, which only generates a strong lateral pressure wave.
- HMX octogen
- the first partial load consists of a mixture of 70-90% by volume octogen (HMX) and 10-30% by volume of an inert plastic binder (e.g. hydroxyl-terminated polybutadiene (HTPB)) and the second partial charge from one Mixture of 70-90% by volume hexogen (RDX) and also 10-30% by volume of a plastic binder consists.
- HMX octogen
- HTPB hydroxyl-terminated polybutadiene
- the second part load should preferably be a metal powder (e.g. aluminum powder) be added to create a blast effect.
- a metal powder e.g. aluminum powder
- the warhead 1 is a ballistic warhead that can be fired from a gun designated, which is to be used against bunker positions and at the side vehicles from the respective position should also destroy.
- the warhead 1 comprises a warhead shell 2 made of steel, one on the front of the warhead shell arranged proximity detonator 3, an adjoining the detonator Splinter plate 4 with heavy metal splinters (e.g. WSM balls) and an explosive charge 5.
- the explosive charge 5 is composed of four, in the direction of the longitudinal axis 6 of the warhead 1 seen, consecutive partial loads 7-10 together.
- the first partial charge 7 adjacent to the splinter plate 4 consists of a mixture of e.g. 90% HMX and 10% of an HTPB binder system and has a relatively high Guerney constant of 2830 m / s. This serves to make the WSM balls special accelerate high in the direction of flight.
- the partial loads 8-10 are used to generate and accelerate the destruction the warhead shell 2 resulting splinters that fly away from the warhead laterally. Much cheaper RDX charges are sufficient for this. Both Splinters can be natural or preformed in the shell act.
- the RDX partial loads 8-10 can range from range to range have a different composition (e.g. charge 8: 85% RDX and 15% HTPB binder system; Charge 9: 90% RDX and 10% HTPB binder system and load 10: 70% RDX, 10% HTPB binder system and 20% aluminum powder).
- the warhead shell 2 is made into a specific one for laboratory use of the warhead 1 Part filled with the first partial load 7. During the pot life of this mixture the second mixture is poured onto the first part load, etc. The layered Pour on different formulations based on the same polymer system then leads to a "tailor-made” effect (detonation speed) the cargo.
