ABSTRACT:
The invention relates to a propellant charge igniter comprising at least two series-connected combustion chambers separated from one another by choke disks, respectively one igniter mixture being housed in these chambers, these igniter mixtures differing from one another with respect to their combustion characteristics and thus exhibiting differing combustion behavior. The combustion chamber volumes are adapted to these igniter mixtures so that the mixture can burn up at the pressure level that is an optimum for the mixtures in each case.
