Pyrotechnic charges that include an explosion generator and an explosive having an outer surface divided into n segments, each segment having kq multiple ignition points for the explosive, k and q being integer numbers greater than 1. The kq multiple ignition points for the explosive are linked by ignition lines forming, for each segment, at least two interleaved partial networks for synchronous ignition of the kq multiple ignition points, each of the partial synchronous ignition networks being linked to a respective partial network detonator.

1. A pyrotechnic charge comprising an explosion generator; andan explosive having an outer surface divided into n segments, each segment comprising kq multiple ignition points for the explosive, k and q being integer numbers greater than 1,wherein the kq multiple ignition points for each segment of the explosive are linked by ignition lines forming, for each segment, at least two interleaved partial networks for the synchronous ignition of the kq multiple ignition points, each of the partial networks being linked to a respective partial network detonator. 2. The pyrotechnic charge according to claim 1, wherein each segment of the outer surface of the explosive comprises two interleaved partial synchronous ignition networks. 3. The pyrotechnic charge according to claim 2, wherein, k and q being even numbers, the kq multiple ignition points form a part by half kq/2 of each of the two interleaved partial networks, each of the two halves of the multiple ignition points being distributed over the surface of the explosive of the segment concerned. 4. The pyrotechnic charge according to claim 3, wherein the kq multiple ignition points of each of the segments are distributed over the surface of the explosive on k rows and q columns, and according to a distribution pitch, a partial synchronous ignition network of a segment being obtained from the other synchronous ignition network of the same segment by rotation of 180° about an axis YY′ parallel to the direction of the columns and passing through a respective central point of distribution of the ignition lines of each of the partial networks. 5. The pyrotechnic charge according to claim 4, wherein a first partial network of a first segment comprises a first ignition point of a first row and a first column linked by an individual ignition line to a second ignition point, of a second column adjacent to the first column and a second row adjacent to the first row to form a first individual ignition pattern of the first partial network, this individual ignition pattern of the first partial network being repeated one ignition point out of two along the k rows and along the q columns, anda second partial network of the first segment comprises a third ignition point, of the first row and the second column linked by another individual ignition line to a fourth ignition point, of the second row and the first column, to form a second individual ignition pattern of the second partial network, this second individual ignition pattern being repeated one ignition point out of two along the k rows and along the q columns. 6. The pyrotechnic charge according to claim 5, wherein the centers of the first and second individual ignition lines are linked by other ignition lines configured so that the distances traveled by the detonation waves for the detonators, of the first segment, applied to each respective central distribution point of the networks, to the multiple ignition points of the first segment are identical, producing a synchronous activation of all said multiple ignition points of the first and second partial networks. 7. The pyrotechnic charge according to claim 6, wherein the other ignition lines are: first lines linking the centers of two consecutive individual lines parallel to the axis XX′,second lines parallel to the axis YY′ linking the centers of two first lines,third lines, parallel to the axis XX′, linking the centers of two consecutive second lines along the axis XX′,two last lines parallel to the axis YY′ linking the centers of the two third lines to the central distribution point of the respective partial network. 8. The pyrotechnic charge according to claim 4, wherein the kq multiple ignition points of a segment are distributed over a square surface of perpendicular axes XX′ parallel to the rows and YY′ parallel to the columns of the partial networks and passing through the central distribution point. 9. The pyrotechnic charge according to claim 4, wherein the distribution pitch of the multiple ignition points is chosen according to the sensitivity of the explosive and so that an accidental initiation of a partial network does not produce the nominal ignition of the pyrotechnic charge. 10. The pyrotechnic charge according to claim 1, wherein the segments each comprise 64 multiple ignition points with k=q=8. 11. The pyrotechnic charge according to claim 1, wherein the explosion generator is on the periphery of the charge surrounding the explosive having a jacket over its outer surface comprising the multiple interleaved networks. 12. The pyrotechnic charge according to claim 11, wherein the jacket comprises two layers in the form of circular tubes fitted into one another, each of the tubes comprising the ignition lines and points of a respective partial network. 13. The pyrotechnic charge according to claim 11, wherein the jacket is made of plastic. 14. The pyrotechnic charge according to claim 1, wherein the explosion generator is inside the charge having a jacket over its outer surface comprising the multiple interleaved networks.
