Pyrotechnic object
The present disclosure relates to a pyrotechnic object, in particular an irritation body, irritation projectile or ammunition, comprising an ignition device, comprising a delay chamber extending along a delay path, in which chamber a delay charge is accommodated, and comprising at least one and preferably a plurality of effect chambers in which or in each of which an effect charge to be ignited is accommodated, wherein the delay chamber is transversely connected to a respective effect chamber via a respective over-ignition opening which branches off from the delay chamber and forms an over-ignition path, wherein in the case of a plurality of effect chambers the plurality of over-ignition openings are arranged successively downstream along the delay path in the order of the effect charges to be ignited.
1. A pyrotechnic object comprising:
an ignition device;
a delay chamber for housing a delay charge, the delay chamber extending from the ignition device along a delay path; and
at least one effect chamber accommodating an effect charge to be ignited, the delay chamber transversely connected to the effect chamber via an over-ignition opening which branches off from the delay chamber and forms an over-ignition path between the delay chamber and the effect chamber,
wherein an over-ignition charge that differs and chemically deviates from the effect charge is introduced into the over-ignition opening to at least partially close the over-ignition opening after combustion of the over-ignition charge and by combustion residue of the over-ignition charge, and to reduce or dampen a propagation of a pressure shock which is produced as a result of an ignition of the effect charge in the effect chamber and acts on the delay chamber via the over-ignition opening.
2. The pyrotechnic object according to claim 1 , wherein the over-ignition charge is introduced into the over-ignition opening over at least 20%, of the length of the over-ignition path.
3. The pyrotechnic object according to claim 1 , wherein the over-ignition charge is pressed into the over-ignition opening.
4. The pyrotechnic object according to claim 1 , wherein the over-ignition charge is introduced into the over-ignition opening as a pasty medium or a flowable medium and is cured therein.
5. The pyrotechnic object according to claim 1 , wherein the over-ignition opening has a cross-sectional change along the over-ignition path.
6. The pyrotechnic object according to claim 5 , wherein the cross-sectional change of the over-ignition opening is a cross-sectional area that changes along the over-ignition path by at least 10%.
7. The pyrotechnic object according to claim 5 , wherein the cross-sectional change is oriented such that the over-ignition opening has, in an ignition propagation direction towards the effect chamber, an increasing cross-sectional area.
8. The pyrotechnic object according to claim 5 , wherein the cross-sectional change is conical-shaped or funnel-shaped.
9. The pyrotechnic object according to claim 5 , wherein the over-ignition opening is a stepped opening.
10. The pyrotechnic object according to claim 5 , wherein the over-ignition charge is arranged in a region of the cross-sectional change such that immobilization and anchorage of the combustion residue of the over-ignition charge in the over-ignition opening is assisted by the cross-sectional change.
11. The pyrotechnic object according to claim 5 , wherein the cross-sectional change of the over-ignition opening is a cross-sectional area that changes along the over-ignition path by at least 25%.
12. The pyrotechnic object according to claim 5 , wherein the cross-sectional change of the over-ignition opening is a cross-sectional area that changes along the over-ignition path by at most 60%.
13. The pyrotechnic object according to claim 1 , further comprising a housing inner body defining the delay chamber and the effect chamber and an outer sleeve body surrounding the housing inner body, the outer sleeve body having a grippable outer side of the object.
14. The pyrotechnic object according to claim 13 , wherein the outer sleeve body is cylindrical.
15. The pyrotechnic object according to claim 13 , wherein the outer sleeve body is configured to seal one or more openings communicating with the delay chamber and the effect chamber.
16. The pyrotechnic object according to claim 1 , wherein:
the at least one effect chamber includes a plurality of effect chambers accommodating effect charges to be ignited;
the delay chamber is transversely connected to the plurality of effect chambers via a plurality of over-ignition openings including the over-ignition opening; and
the plurality of over-ignition openings are arranged successively downstream along the delay path in the order of the effect charges to be ignited.
17. The pyrotechnic object according to claim 1 , wherein the over-ignition charge is introduced into the over-ignition opening over at least 30% of the length of the over-ignition path.
18. The pyrotechnic object according to claim 17 , wherein the over-ignition charge is introduced into the over-ignition opening over at most 90% of the length of the over-ignition path.
19. The pyrotechnic object according to claim 1 , wherein the over-ignition charge is introduced into the over-ignition opening over at least 50% of the length of the over-ignition path.
20. The pyrotechnic object according to claim 1 , wherein the pyrotechnic object is one of an irritation body, irritation projectile or ammunition.
