Abstract (en)

Cold solid propellant, comprises gel comprising a liquid compound comprising oxidizing or reducing liquid compounds, in a cold hardened gel, where the liquid compound is gelled by a polymeric organic gelling agent and containing a filler particle comprising reducing filler particle, when the liquid compound is oxidizer, or oxidizing filler particle, when liquid particle is reducer. Independent claims are included for: (1) a pyrotechnic charge comprises the cold solid propellant; (2) a process for preparing the cold solid propellant comprising obtaining a cold gel by introducing the liquid compound in the mixer, preferably cooled to obtain the cold liquid by stirring, introducing a polymeric organic gelling agent, which is optionally precooled, in the mixer containing the liquid compound maintained and cooled by stirring, introducing filler particle, which is optionally cooled, in the mixer containing the liquid compound and the gelling agent mixture maintained and cooled by stirring, and agitating the cold mixture containing the liquid compound, oxidizer or reducer, gelling agent and filler particle in the mixer, and hardening the cold gel by stopping the stirring with optionally cooling; and (3) a process for preparing the pyrotechnic charge comprising preparing the cold solid propellant, casting of gel and hardening of the gel in a structure.

Abstract (fr)

La présente invention a pour objet: - des propergols solides froids, consistant en des gels durcis froids, lesdits gels comprenant au moins un composé liquide, choisi parmi les composés liquides oxydants ou les composés liquides réducteurs, gélifié par au moins un agent gélifiant organique polymérique et renfermant au moins une charge particulaire choisie parmi les charges particulaires réductrices, lorsque ledit au moins un composé liquide est oxydant, ou les charges particulaires oxydantes, lorsque ledit au moins un composé liquide est réducteur ; - des chargements pyrotechniques, comprenant de tels propergols solides ; ainsi que - des procédés d'obtention desdits propergols et chargements.
