The invention discloses powder materials for spreading by dispersion means to produce a camouflage cloud which is effective in the infrared. The material comprises at least a powder in which the grains are covered by a coating which is chemically inert with respect to said grains and capable of withstanding the dispersion temperature or lower, and which does not oxidize in free air. The dispersion means comprise at least one hot gas generating turbine (11) with an outlet nozzle (10), a reservoir (1) with a mixer (3) holding the powder material in suspension in the vector liquid, the reservoir being connected to the outlet nozzle (10) by an electric pump (8).
Le secteur technique de l'invention est celui des matériaux pulvérulents destinés à être répandus par des moyens de dispersion de façon à produire un nuage de camouflage efficace dans le domaine infrarouge. Le matériau selon l'invention est caractérisé en ce qu'il comprend au moins une poudre dont les grains sont recouverts d'un enrobage chimiquement inerte vis-à-vis du grain, résistant aux températures inférieures ou égales à la température de dispersion, et ne s'oxydant pas à l'air libre. La présente invention peut être appliquée aux dispositifs générateurs de fumée.
