The present invention relates to the field of propellant devices and more particularly to the propellant devices used in weapon systems and munitions. The invention has the two advantages of minimizing the risk associated with accidental attack to which propellant devices may be exposed thanks to the filling of the central channel commonly provided along the core of the cylindrical explosive charge and of greatly increasing the effectiveness of these propellant charges by the use of explosive materials having a very high burn rate.

Propellant device of enhanced performance

Embodiments of the invention relate to a safety lighter intended to initiate the combustion of a pyrotechnic device, the lighter including a lighter body () having a cylindrical void () of axis XX', and a pyrotechnic slide-in module () including pyrotechnic means () of initiating the combustion of the pyrotechnic device, the pyrotechnic slide-in module () being able to be displaced in the cylindrical void, from a so-called safety position (Ps), providing isolation between the pyrotechnic means of the slide-in module and the pyrotechnic device to be initiated, to a so-called initiation position (Pi), intended to provoke the combustion of the pyrotechnic device.

Safety lighter for pyrotechnic device

The slapper type initiator comprises essentially: a connector unit ( ) having two connection pins ( ), a first dielectric foil ( ) with two drilled holes ( ), with a fuse ( ) formed on the rear face of this first dielectric foil, a second dielectric foil ( ) on the front face of which there are formed two metal pads ( ) facing said holes, a perforated plate ( ) and a body ( ) containing a pyrotechnic charge . The assembly is hermetically sealed. The first foil introduces a galvanic discontinuity that ensures a well-defined firing voltage, with a value high enough to prevent induced parasitic currents.
