Abstract
The present invention relates to a method for avoiding uneven ignition when initiating artillery propellant powder charges (1) which comprise a plurality of partial charges of the so-called modular type and which are initiated by means of laser initiation systems or conventional ignition cartridges. The invention also includes artillery propellant powder charge modules designed in accordance with this method. The invention is also based on the fact that each such charge module or modular charge has on the one hand been provided with an initiating charge (18, 19) at each end of the central ignition channel (11), where this initiating charge can consist for example of black powder, and, on the other hand, the middle part of the same ignition channel has been provided with a specially designed firing unit (14) consisting of a number of ring elements between which narrow ignition gaps (17) are maintained.
