Definitions

  • the invention relates to an explosive for warheads and a rocket solid propellant, consisting of a high-energy secondary explosive with inorganic perchlorate and metal content of high oxygen affinity, as well as protective agent and binder.
  • the invention has for its object to provide an explosive with a high energy content per unit volume.
  • the energy conversion should take place very quickly and be complete.
  • the invention solves this problem in that, in the case of a secondary explosive, the oxygen balance is balanced by the perchlorate component, for example for a complete reaction to carbon dioxide and water.
  • the perchlorates of the alkali and alkaline earth metals are provided as perchlorates.
  • Such perchlorates are inexpensive, easily accessible and can be prepared.
  • potassium or calcium perchlorate are used as perchlorate. Because of its low hygroscopicity, potassium perchlorate offers special processing advantages. Calcium perchlorate, on the other hand, increases performance due to its higher density and higher specific oxygen content.
  • the explosive gas volume and the release of energy are controlled by the metal portion by reducing the carbon dioxide and water vapor produced by the metal to carbon monoxide and hydrogen. Due to the higher affinity of the metal for oxygen compared to carbon and hydrogen, the metal reacts violently with carbon dioxide and water. These are reduced and a significant amount of energy is released. As a result, the explosive gas mixture is additionally heated, which significantly increases the performance of the explosive. Particularly favorable values are obtained if the stoichiometry of the metal component reduces the explosive gases to hydrogen and carbon monoxide. If a particularly large heat release is desired with a reduced explosive gas volume, the explosive gases are reduced to elemental carbon and hydrogen by further increasing the metal content.
  • heavy metals with a high affinity for oxygen such as zircon, can also be used.
  • An energy-rich, relatively dense and inexpensive rocket fuel is according to claim 10.
  • the explosives are mixed with rocket-solid fuel-specific phlegmatizing and binding agents as well as light metals.
  • Essential for the invention is: There are universal explosives or explosive formulations with maximum energy yields.
  • the explosives according to the invention can be easily adapted to technical requirements, the energy content being higher than in the case of known explosives.
  • the invention is also without substantial change for rocket-proof fuels can be used by using the lightest possible metals and special desensitizing and binding agents.
  • the plate was penetrated, the hole diameter being 7mm.
  • the metal is said to explode. To do this, it is necessary to evaporate the metal first. As is known, this requires a high level of energy, since the heat of vaporization of aluminum, calcium, silicon is very high. When metals are added to normal explosives, their relatively low heat of explosion is usually insufficient to evaporate the metal quickly and completely. This also consumes a lot of the heat of the explosion and thus the temperature before the metal is burned, which results in a delay in the reaction. The energy of the explosives used must therefore first be increased.
  • this is achieved in that a safe explosive such as TNT, hexogen, octogen or nitropenta is poured, melted, mixed or combined with a solvent in such a large amount that a complete combustion with a balanced oxygen balance occurs , e.g. 16 moles of TNT + 21 moles of CA (ClO4) 2 or 8 moles of hexogen + 3 moles of Ca (ClO4) 2.
  • a safe explosive such as TNT, hexogen, octogen or nitropenta
  • This basic mixture is intimately mixed with the metal dust and fused or glued.
  • the proportion of the metal is at least so high that the water is reduced to hydrogen and the carbon dioxide to carbon monoxide. With further reduction, the energy increases, but the explosive gas volume decreases because the carbon monoxide is reduced to carbon. The resulting amounts of energy are very high without afterburning with the atmospheric oxygen.
  • the above mixture of TNT / Ca (ClO4) 2 can be a mixture of 37.6% AL, 62.4% CA (CLO4) 2 with a specific weight of 2.67 g / cm3 are added.
  • the energy is 31.4 MJ / dm3.
  • High-energy rocket fuels are created by desensitizing mixtures containing ammonium perchlorate.
