LES DISPOSITIFS DE SECURITE ET DE MISE A FEU HAUTE ENERGIE (DSMF) A BASE D'ARTIFICES PYROTECHNIQUES DU TYPE 'DISPOSITIF A ELEMENT PROJETE OU SLAPPER': INTERET POUR L'INITIATION DES FONCTIONS PYROTECHNIQUES DES MISSILES (PROPULSION ET CHARGE MILITAIRE)

摘要

The Safe and Arm Units (SAU) using pyrotechnical devices as the "stopper" are interesting to fulfill ignition sequences of motor and warhead in a missile. Actually safety requirements for motor ignition become close to safety requirements for warhead ignition. The electrical igniters (low and medium energy levels) should be used only in a pyrotechnical train equipped with a physical barrier between the igniter and the other parts of the train. The stopper SAU's are able to be used without pyrotechnical train interruption because of their own safety caracteristics. This property make these systems very attractiv for modern missiles ignition functions.
