Abstract

Générateur pyrotechnique de gaz à faible durée de combustion, destiné notament à être utilisé comme propulseur d'accélération d'un engin autopropulsé. Le générateur est muni d'un chargement pyrotechnique constitué de rondelles de propergol solide disposées sensiblement parallèlement les unes aux autres et ménageant au moins un canal longitudinal d'évacuation des gaz de combustion en direction d'au moins une tuyère, et se caractérise en ce que le chargement pyrotechnique est constitué de plusieurs ensembles 11 à 14 de rondelles de propergol séparés par des déflecteurs 8, 9, 10 qui sont disposés sensiblement parallèlement aux plaques de propergol et dont le bord 8a, 9a, 10a situé vers le canal longitudinal d'évacuation des gaz est en dépassement.
