Abstract

Corps de poudre à une ou plusieurs bases pour charges propulsives, comportant au moins un canal intérieur. Les diamètres des canaux intérieurs des corps de poudre formant une charge propulsive sont différents, au moins une partie de ces diamètres étant plus petits que le diamètre critique relevant de la pression de mise à feu et déterminant pour la pénétration de la flamme de mise à feu dans les canaux intérieurs, au moins une partie des canaux intérieurs étant mis à feu avec un certain retard uniquement lorsque la pression des gaz s'élève au-delà de la pression de mise à feu.Powder body with one or more bases for propellant charges, comprising at least one internal channel. The diameters of the internal channels of the powder bodies forming a propellant charge are different, at least some of these diameters being smaller than the critical diameter falling under the firing pressure and determining for the penetration of the firing flame in the interior channels, at least part of the interior channels being ignited with a certain delay only when the gas pressure rises above the ignition pressure.
