Title (EN) MECHANICAL DRIVE DEVICE COMPRISING AN IGNITION SYSTEM
(FR) DISPOSITIF D'ENTRAÎNEMENT MÉCANIQUE COMPRENANT UN SYSTÈME D'ALLUMAGE
Abstract:
(EN) The invention relates to a mechanical drive device comprising an ignition system having a control device (124), a laser diode (130) capable of emitting an optical signal in the event of receiving a firing command, an optical line (140) capable of transmitting the optical signal, an arming device (136) capable of exhibiting a first state, termed the disarmed state, in which the arming device (136) prevents the propagation of the optical signal in the optical line (140), and a second state, termed the armed state, in which the arming device (136) allows the propagation of the optical signal in the optical line (140), the armed state being activated only in the event of receiving an arming command, and a pyrotechnic initiation device (128) comprising a pyrotechnic secondary composition (134), suitable for being initiated by said optical signal and for igniting the solid charge of the gas generator (12).
(FR) L'invention concerne un dispositif d'entraînement mécanique comprenant un système d'allumage comprenant 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.
