The present invention relates to a method and an apparatus for producing rapid cross-ignition of preferably elongate powder or pyrotechnic charges, such as the propellant charges in impulse motors for correcting the trajectory of shells, rockets and missiles. The cross-ignition is produced by initiation of an elongate, extremely fast-burning or detonating primer charge with an extremely low explosive force which has been arranged in contact with at least part of the periphery of the propellant charge. The primer charge forms a tube whose cross-ignition e...
An ignition device for elongate main propellant powder charges such as gas generators for trajectory-correcting impulse motors, the ignition device comprising: a fast-burning or detonating fuse positioned along each elongate main propellant powder charge, said fast-burning or detonating fuse being arranged to communicate with at least portions of a surface of the elongate main propellant charge, said fast-burning or detonating fuse including a fast-burning layer surrounding an inner core which contains a slower burning powder, said fast-burning layer bei...
