Abstract: An infrared decoy member is provided with a pyrotechnic chain for ejection and ignition incorporated in a unit. The ejection charge is mounted to slide in a cavity which allows the ejection of the unit as well as of adjacent infrared charges. A slide, which can be released when an acceleration threshold is crossed and on condition of ejection could ensure the transmission of fire to a transverse channel leading to useful charges. A second fire-transmitting chain which is independent, makes it possible to excite previously a similar decoy member located below.

Abstract: A standard launcher module for various missiles, in particular flares, comprises a flat wall forming a base, provided with male engagement members. In the position engaged on the support incorporated in the aircraft, a connector is active. Provided in a central groove is a series of electrical initiators connected selectively to the connector and located opposite counterpart relay channels which lead respectively to the useful charges. A sliding bar located in the groove has orifices, located according to the working geometry of the initiators. Finally, a motor connected to the connector allows the movement of the bar between a safety position and an armed position.

Abstract: This invention relates to the safety of ammunitions.The projectile of a cartridge has a base which houses a safety stop consisting of a transversely slidable valve. A device ensures that the valve cannot be released until the projectile has been subjected to a powerful acceleration. Another safety device very advantageously ensures that the pyrotechnical chain inserted in the base functions only when the pressure of the ejection charge has been able to release a sealing-block.In particular, the invention may be applied to infra red window releasing cartridges.
