Abstract
An electropyrotechnic device for sequentially triggering the operation of a battery of gas generators. The ignition of double-base propellant blocks is obtained by the combination of EFI and an IFOC, arranged so that the airtight barrier between the cavity containing the donor secondary explosive and the downstream chamber containing the secondary receiving explosive is only one part of the closing element of the back end carrying the nozzles, integral with the ring. The control electronics of the EFI are contained inside a housing capping the back end of the powder generator with the entire system being closed by a cap.
