Abstract

L'invention concerne un système d'allumage d'une charge solide d'un générateur de gaz. Le système d'allumage est caractérisé en ce qu'il comprend un dispositif (124) de pilotage, une diode (130) laser adaptée pour émettre un signal optique en cas de réception d'un ordre de mise à feu, une ligne (140) optique adaptée pour transmettre le signal optique, un dispositif (136) d'armement adapté pour présenter un premier état, dit état désarmé, dans lequel le dispositif (136) d'armement empêche la propagation du signal optique dans la ligne (140) optique, et un deuxième état, dit état armé, dans lequel le dispositif (136) d'armement permet la propagation du signal optique dans la ligne (140) optique, l'état armé étant activé qu'en cas de réception d'un ordre d'armement, et un dispositif (128) d'initiation pyrotechnique comprenant une composition (134) pyrotechnique secondaire, adaptée pour être initiée par ledit signal optique et pour allumer la charge solide du générateur (12) de gaz.
