An igniter for propulsion unit including a receptacle having at least one opening through which passes a conducting line connected to an ignition carrier of a slapper contained within the receptacle, the igniter being characterized in that at least one elastomer material is disposed between the ignition carrier and the opening such that the pressure of the gases generated by the propulsion unit which is ignited pushes the elastomer material at the vicinity of the opening of the receptacle so that this elastomer material blocks the opening and avoids any gas leak through this opening.

A time control device for the movement of a micro-machined or micro-engraved counterweight with respect to a substrate, said counterweight incorporating at least one face having at least one indentation intended to cooperate with at least one other indentation on a housing in which said counterweight moves so as to ensure the delaying of said movement of said counterweight, wherein said one indentation on said counterweight respectively on said housing receiving said counterweight is made on at least one flexible tongue itself integral with said counterweight respectively said housing, said at least one flexible tongue being able to be deformed by bending during the displacement of said counterweight.

A micro-machined or micro-engraved safety and arming device for a projectile pyrotechnic train, said device comprising a substrate onto which a shutter is positioned to ensure the blocking of a channel, said shutter being mobile in translation on said substrate, said shutter being held immobile in the safety position by at least one acceleration lock that is released further to the application of the axial acceleration imparted to said projectile during firing, wherein said acceleration lock is constituted by at least one breakable tongue linking said shutter to said substrate, said tongue being oriented and dimensioned such that the axial inertial stresses developed during firing and exerted on said shutter cause said tongue to break.

Safety and arming device with breakable lock

A programming device for the fuse of a projectile using programming coils transmitting a programming signal by induction to a receiver integral with the fuse, wherein the programming coils are integral with a substantially cylindrical wall of a corridor in which the projectile translates axially, the programming coils being made in the form of several elementary coils each encircling a ferrite core parallel to the axis of the corridor, the coils being distributed along several lines parallel to the corridor axis, the coils of one line being longitudinally staggered with respect to the coils of the neighboring line or lines.

A micro-machined or micro-engraved safety and arming device for a pyrotechnic train of a projectile to which an axial spin motion is imparted during firing, the device includes a shutter to interrupt the pyrotechnic and being held immobile by at least two locks, a first lock or axial acceleration lock that is released further to the application of the acceleration during firing and a second lock that is a centrifugal lock released further to the spinning of the projectile.

A retractable turret rotatable on a platform, including an active system orientable in vertically extendable elevation, and in azimuth, a protective cowling for the active system and for closing a caisson, wherein the turret includes, for vertically extendable deployment and rotation of the active system, first and second arms forming a deformable quadrilateral on either side of the active system, a first manual means for controlling deployment of the active system by activating the first arm, and a second manual means for controlling the orientation in vertically extended elevation and in horizontal azimuth of the active system by moving the second arm.
