Definitions

  • the invention relates to a method for producing a fuel with a proportion of solid components which is reacted with an oxidizer in a drive system which is independent of the outside air, the proportion of which contains an alkali metal hydride which consists of an inert substance, preferably an alkane, existing liquid component is embedded, and about 1.5 to 5 percent by weight of a stearate being added to the solids content.
  • propulsion systems are used in which the combustion of a fuel takes place independently of the supply of oxygen from the environment by an oxidizer, which is usually present in liquid form as a further component in the fuel.
  • the fuel component of such fuels is either also in the form of a liquid, for example in the form of a hydrocarbon, as hydrazine or as cryogenic hydrogen, or solid fuels such as hydrides - preferably the alkali metals - or metal powders are used for this purpose, which frequently are embedded in binders. While solid fuels have the advantage of a high energy density, liquid fuels are generally easier to convey and control.
  • EP 0 187 212 has therefore already proposed the use of a fuel which consists of an alkali metal hydride, for example lithium hydride (LiH), exists, which is embedded in granular form in liquid paraffin (C10 H20), and which is thereby present in pasty form.
  • an alkali metal hydride for example lithium hydride (LiH)
  • LiH lithium hydride
  • the object of the invention is therefore to specify in the method for producing a fuel according to the generic term, by means of which such destabilization is reliably avoided and, at the same time, by which the storage and conveying capacity of the fuel produced is sustainably improved.
  • a fuel produced in this way which consists of a mixture of lithium hydride (LiH) and an approximately 5% addition of lithium stearate (C17 H35 COOLi), which is embedded in low-viscosity paraffin (C10 H20), together with an oxidizer from dissolved in water Lithium chlorate (LiClO3) suitable as a fuel in thermodynamic drive systems for torpedoes.
  • LiClO3 Lithium chlorate
