Definitions

  • the invention relates to a gas-generating mixture of a fuel, an oxidizer, a catalyst and a coolant.
  • Gas-generating mixtures of the aforementioned type - also called gas generator sets - are characterized in that they enable a high gas yield (> 14 mol / kg) during combustion. They are used for rocket and barrel weapon drives as well as for inflatable restraint (airbag) and rescue systems. In the civil sector in particular, thermal-mechanical insensitivity and non-toxicity of the starting mixtures, but also a lack of toxicity in the resulting gases are required. Many systems in use do not meet these requirements, or meet them only very inadequately.
  • the oxidizer is Cu (NO3) 2 * 3Cu (OH) 2 and the catalyst consists of a metal or a metal alloy on a support.
  • the catalyst which is also used according to the invention is primarily used to reduce harmful gas (CO and NO), the term "catalyst" in the broader sense here denoting an active reaction component which can be implemented itself and has a reaction-guiding and / or reaction-accelerating effect.
  • the carrier serves to present the main component with a large specific surface and a defined grain size distribution. Another property of the carrier is to develop a cooling effect through physical and / or chemical processes - in a special phase of the reaction, that goes beyond a pure capacitive cooling effect.
  • the carrier can also act as a promoter of the main component. Not only the metal catalyst, but also the oxidizer are thermally and mechanically stable and in particular also not hygroscopic.
  • N-rich and C-poor fuels include the well-known fuels TAGN (triaminoguanidine nitrate), NIGU (nitroguanidine), NTO (3-nitro-1,2,3-triazol-5-one) and the GZT (diguanidinium-5,5 '), which is characterized by a particularly high nitrogen content. -azotetrazolate) (DE 4 108 225).
  • TAGN, NIGU, NTO, but in particular GZT are preferably used in the mixture according to the invention when used for rescue and restraint systems.
  • the combustion temperature can be determined very precisely by thermodynamic calculation. It is 2345 K. With the same GZT fuel and a balanced oxygen balance, other oxidizers deliver higher combustion temperatures. For example, they are at KNO3 at 2501 K, at N H4 NO3 at 2850 K and at K Cl O3 at 3248 K.
