    • The firing chain of the invention includes an arming device (40) mobile between a rest and an active position., two locking members (14, 16) for locking the arming device in a rest position and an active position, an arming pyrotechnical retarder (22), a squib (26) ignited at the ejection of the missile and igniting the arming retarder and releasing the first locking member (14) in order to allow the arming device to be switched into an active position, and a trajectory pyrotechnical retarder (32). A first relay charge (29) is adapted to be ignited at the end of the combustion of the arming retarder and to trigger the ignition of the trajectory retarder and the actuation of the second locking member (16) for locking the arming device in an active position and a second relay charge (34) is adapted to be ignited at the end of the combustion of the trajectory retarder and to trigger the ignition of the main charge.
    • 本发明的发射链包括在休息和主动位置之间移动的布防装置(40),用于将布防装置锁定在休息位置和主动位置的两个锁定构件(14,16),布防烟火缓速器 22),在导弹弹出时引燃点火器(26)并点燃所述防火延迟器并且释放所述第一锁定构件(14)以允许所述布防装置切换到主动位置,并且轨迹烟火缓速器 32)。 第一继电器充电装置(29)适于在所述布防延迟器的燃烧结束时被点燃并且触发所述轨迹延迟器的点火和所述第二锁定构件(16)的致动,以将所述布防装置锁定在主动 位置和第二继电器充电(34)适于在轨迹延迟器的燃烧结束时被点燃并触发主电荷点火。
