Abstract

La présente invention se rapporte à un chargement pyrotechnique enroulé en forme de spirale autour d'un axe central. Préférentiellement, le chargement est constitué d'une bande souple formant plusieurs spires sur lesquelles des brins de propergol sont fixés parallèlement à l'axe central en utilisant une surface réduite de fixation, les brins de propergol placés à l'intérieur du chargement étant en contact avec les deux spires situées de pan et d'autre de ces brins, la bande souple presentant un caractère inhibiteur eu égard aux caractéristiques de combustion des brins de propergol. Application à la génération d'un grand débit de gaz chauds utilisable notamment à la propulsion d'un engin.
