Abstract

Igniter device comprises a powdered charge, ignition of which is obtained by an initiating system used for setting off small and average size rockets. The igniter charge consists of a powder, combustion of which produces little or no gas and which is contained in a rigid box not destroyed at the instant of ignition and having an opening of only limited area closed by a low resistance wall fracturing on firing. The low resistance wall is fixed to the rigid box by a sealing fixing element. A source of gaseous prod. is provided to ensure the directed projection of the incandescent particles, during the rupture of the low resistance wall. Not only enables the igniter charge to be reduced in size since premature destruction of the casing does not occur but also eliminates the possible disruption of thin walled propellant charges by the jet effect of the high gas volume.
