Abstract
The invention relates to an electrothermal ignition device for igniting a powder propellant charge ( ), which comprises at least one electrically-conductive wire ( ), that extends, at least partially, through the propellant charge, and can be connected to a current source ( ). The electrically-conductive wire ( ) is coated with a pyrotechnical ignition mixture ( )so that the ignition device can have a low electrical-energy requirement and be easily adapted to the different requirements placed on it. A mixture on a potassium perchlorate-zirconium (KClO —Zr) base has proven to be an advantageous ignition mixture.
