Séquenceur pour dispositif sécurisé de mise à feu formant un microsystème électromécanique, comprenant : - un canal (1) de transmission ; - une barrière (2) apte à se déplacer en translation entre une position de repos obturant totalement le canal (1) et une position de libération totale du canal ; et - un organe mobile (3) coopérant avec la barrière (2) et apte à se déplacer, sous l'action d'un signal de validation, entre une position de verrouillage initiale interdisant le déplacement de la barrière (2) jusqu'à la position de libération totale et une position de déverrouillage autorisant le déplacement de la barrière (2) jusqu'à sa position de libération totale. Le séquenceur comprend en outre : - un premier ensemble (A, A') de moyens mécaniques apte à empêcher le déplacement de l'organe mobile (3) jusqu'à sa position de déverrouillage lorsque le déplacement de la barrière (2) est initié avant celui de l'organe mobile (3), et ce tant que le déplacement de la barrière (2) de la position de repos à la position de libération totale est inférieur à un seuil de déplacement ; et - un deuxième ensemble (B, B') de moyens mécaniques apte à empêcher le déplacement de l'organe mobile (3) vers sa position de déverrouillage lorsque l'organe mobile (3) est actionné préalablement au déplacement de la barrière (2) vers la position de libération.
摘要:
The subject of the invention is a micro-initiator 1 comprising a pyrotechnic initiation means 3 that can be initiated by a first ignition means 13 and is itself intended for igniting a charge 5. This micro-initiator is characterized in that the pyrotechnic means 3 is formed by an energetic composition placed on a first layer 2 of a substrate and able to be connected to the charge 5 via an ignition channel 6 which is closed off by a movable screen 8, which is located on a second substrate layer 7 incorporated in the initiator, which screen 8 can be moved from a safe position to an armed position through the action of the gases generated by a first pyrotechnic generator 9 which is itself incorporated into the micro-initiator 1 and initiated by a second ignition means 14.

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.

The device concerns a safety lighter designed to initiate a pyrotechnic device into combustion, with the lighter including: a lighter body (10) with a cylindrical groove (12) of XX' axis; a pyrotechnic drawer (14) including pyrotechnic methods (70, 74, 30) to initiate the pyrotechnic device into combustion, with the pyrotechnic drawer (14) being capable of moving into the cylindrical groove, from position (Ps) of security, guaranteeing isolation between the pyrotechnic methods of the drawer and the pyrotechnic device to be initiated into combustion, toward position (Pi), referred to as that of initiation, designed to cause combustion of the pyrotechnic device. Suitable for use with firing rockets, missile motors, gas generators for pressurization of the reservoir, pyromechanisms.
摘要:
Miniature arm fire and safe and arm devices include an electrically operated pyrotechnic initiation device (5) to generate a detonation wave upon command and a movable pressure barrier (9) that blocks propagation of the detonation wave if the device is not intended to be fired and opens a window (12) to transfer the detonation wave externally of the device. The detonation wave may in alternate embodiments be a subsonic flame front and pressure wave or a supersonic shock wave, respectively. An electromagnet (7) may serve to move the pressure barrier. Detonation waves output from the device have application in igniting an explosive train, either directly or indirectly, the latter by operating an electrical switch. In the arm fire device, the barrier automatically prevents a detonation output when electrical power is removed from the device. In the safe and arm device, the barrier, once moved out of the way, remains out of the way, even when electrical power is removed. Various forms of miniature single operate electrical switches are described that may be operated by the foregoing devices.

摘要:
@ The fuse comprises a first striker member (2) which is movable within the body (1) of the fuse and is able to come into contact with a detonator (4) to cause it to explode, and a slide (3) which is movable in a direction substantially orthogonal to that in which the striker member (2) is movable and which carries the detonator (4); within the said slide (3) there is disposed a second striker member (14) which is movable from a first position, in which it elastically deforms a spring (17) and is held at a predetermined distance from the detonator (4), to a second position in which it comes into contact with the detonator to cause it to explode, the movement of the second striker member (14) being delayed by delay means (20) operable to allow the movement of the striker member itself from the first-defined first to the second position only after a predetermined time.
