Abstract (en)
[origin: WO8601584A1] In a propellant module with a combustible container the ignition charge for all charge graduations and in every charge position must be so arranged that in the low and high gas pressure range, while complying with the same charge graduations, a regular gas pressure pattern and a reproducible blasting outflow are made possible, and in addition a modular design is ensured by which it is possible to achieve as simultaneous ignition as possible over the whole length of the charge, for any desired chargeability and exchangeability of the module. The propellant module (1) comprises over the entire length of the module (1) a co-axially-arranged free ignition channel (3) which is formed by an ignition charge (5, 7) which is symmetrically arranged to the end-walls (8, 9) of the container (10). The limiting wall (4) of the ignition channel (3) may consist of a tube (14) in whose wall cross-section an ignition charge (5) is incorporated. The wall cross-section of the channel (3) may however also consist of a combustible support tube (6) and an ignition charge preferably made of annular pieces. The symmetrical container design enables any desired chargeability and ignition from either endside (8) or (9). The free cross-section of the ignition channel (3) ensures a virtually simultaneous ignition of the ignition charge (7) over the overall charge length.
