| 摘要 |
The present invention relates to a method and an arrangement for producing rapid cross-ignition of preferably elongate powder or pyrotechnic charges, such as the propellent charges in impulse motors for correcting the trajectory of shells, rockets and missiles. According to the invention, the cross-ignition is produced by initiation of an elongate, extremely fast-burning or detonating primer charge (28-33 or 34-39) with an extremely low explosive force which has been arranged in direct contact with at least part of the periphery of the propellent charge (7-12 or 13-18). The primer charge characterizing the invention can thus be given the form of a tube (42) whose cross-ignition effect is advantageously complemented by an inner, more slowly-burning powder core (43) which is combusted with deflagration.
