A modular pyrotechnic launch unit includes a launch module, a first module, and a second module. The launch module includes a launch barrel. The first module is coupled in series to the launch module. The first module includes a first ignition state in which the first module ignites a pyrotechnic element that will then pass through the launch barrel. The first module also includes a first pass-through state in which the first module allows a pyrotechnic element ignited by another module to pass through the first module. The second module is coupled in series to the first module. The second module includes a second ignition state in which the second module ignites a pyrotechnic element that will then pass through the first module and through the launch barrel.

A counter-swarm firework includes a shell casing, multiple streamers positioned in the shell casing, a burst charge positioned in the shell casing and configured to disperse the multiple streamers from the shell casing when discharged, a pusher plate positioned in the shell casing between the burst charge and the multiple streamers, a fire suppressant layer positioned between the burst charge and the pusher plate, and a kick charge configured to launch the shell casing and its contents prior to discharging the burst charge. The fire suppression layer may be configured to suppress heat generated by the discharge of the burst charge.

A firework packaging system includes a firework packaging assembly, including a first and second firework assemblies, each including a base unit and a plurality of launching tubes mounted in the base unit, such that the first firework assembly and the second firework assembly are packaged in an opposing overlapping configuration, with internal overlap such that first tubes slide into second tubes, or external overlap such that first tubes slide between adjacent second tubes. The fireworks packaging system can further include a shipping crate, containing a plurality of cases, each containing a plurality of firework packaging assemblies.

A firecracker and firecracker arrangement. The firecracker includes an outer sheath having two face sides and that is closed at both face sides with a layer of barrier material. Pyrotechnic effect elements and a bursting charge are arranged inside the outer sheath. A first ignition line that penetrates the barrier material is guided up to the bursting charge. The bursting charge is accommodated inside a completely closed, cylindrical jacket that is arranged coaxial to the outer sheath such that a longitudinal center axes of the outer sheath and of the cylindrical jacket coincide. The first ignition line is guided through an opening in the cylindrical jacket to the bursting charge. The pyrotechnic effect elements are arranged to form a predefined geometric shape in at least one plane extending transverse to the longitudinal center axis of the outer sheath.

A fireworks connection structure for continuous discharge of groups of fireworks, including a group of fireworks formed by a plurality of firework tubes, wherein the group of fireworks further comprises female connecting firework tubes arranged at the head end of the group of fireworks for igniting the group of fireworks and at least one male connecting firework tube matched with the female connecting firework tubes; the female connecting firework tube can be amounted above the male connecting firework tube of another group of fireworks; the female connecting firework tube is equipped with a fuse inside, of which one end is inside the female connecting firework tube and the other end extends beyond the female connecting firework tube for igniting the group of fireworks; the fuse is positioned in the female connecting firework tube in such a manner that after the female connecting firework tube is amounted above the male connecting firework tube of another group of fireworks, the male connecting firework tube of another group of fireworks may ignite the fuse. The connecting method of the application is convenient and simple for there is no need to connect the actual fuses manually, so that the risk of accidents upon connecting fuses may be prevented. Moreover, with this method, groups of fireworks can be connected and detached quickly, without any damage to the fireworks devices, making possible versatile combination and arrangement between fireworks groups in an easy manner.
