摘要： A fireworks aerial display shell is provided with multiple casings of cylindrical configuration that are joined together in end-to-end relationship. Each casing defines an interior volume in which an effects charge is packed. A plug is positioned between the effects charges and has an opening through which an ignition source passes to ignite one of the effects charges as a result of burning of another of the effects charges. An outer casing may surround at least parts of the multiple cylindrical casings and includes multiple partially ball-shaped segments.

摘要： A fireworks aerial display shell is provided with lift charges positioned at opposite ends of a casing that additionally contains an effects charge. Fuses are operatively associated with the lift charges and the effects charge in a manner to ignite the lift charges a period of time before igniting the effects charge. When either one of the ends of the casing is placed facing a closed bottom of a launch tube of a reusable mortar, the burning lift charge at that end of the casing when ignited exerts a propelling force to propel the aerial display shell upwardly out of the launch tube to an intended height before the effects charge is ignited to create a pyrotechnic visual effects display.

摘要： Pyrotechnic systems and associated methods are disclosed. In one embodiment, a pyrotechnic system includes a combustible material in a housing having a first and second portion. The first portion of the housing can have an inlet for receiving combustion products and the second portion can have an outlet to propagate combustion between the second portion of the housing and the combustible material. The system can further include a combustible carrier material movable from the first portion of the housing to the second portion of the housing. The combustible carrier material can be ignited in a first portion of the housing and capable of sustaining combustion while being moved to the second portion of the housing. Additional embodiments can include a seal positioned to block a migration of combustion products between the first and second portions of the housing when the combustible carrier material is in the first portion of the housing. Still further embodiments can include a vent system located proximate to the first portion of the housing and the inlet wherein the vent system includes a passageway to allow combustion products to migrate away from the first portion of the housing and/or the inlet. In yet a further embodiment, the system can include at least one gasket positioned proximate to the outlet to prevent the migration of combustion products to the combustible material except from the outlet.
摘要翻译： 披露烟火系统和相关方法。 在一个实施例中，烟火系统包括具有第一和第二部分的壳体中的可燃材料。 壳体的第一部分可以具有用于接收燃烧产物的入口，并且第二部分可以具有出口以在壳体的第二部分和可燃材料之间传播燃烧。 该系统还可以包括可从壳体的第一部分移动到壳体的第二部分的可燃载体材料。 可燃载体材料可以在壳体的第一部分中被点燃，并且能够在移动到壳体的第二部分的同时维持燃烧。 另外的实施例可以包括定位成当可燃载体材料在壳体的第一部分中时阻挡燃烧产物在壳体的第一和第二部分之间迁移的密封件。 另外的实施例可以包括位于壳体的第一部分附近的排气系统和入口，其中排气系统包括允许燃烧产物远离壳体的第一部分和/或入口迁移的通道。 在又一个实施例中，系统可以包括至少一个靠近出口设置的垫圈，以防止燃烧产物迁移到除了出口之外的可燃材料。

摘要： A system and method for launching projectiles, such as fireworks projectiles, which explode in the air into a pyrotechnic display. The projectile includes a shell constructed from a binding agent and an explosive additive which explodes the shell into small particles. The explosive additive, which may be nitrocellulose, causes the exploded particles to be rapidly burned and consumed to form lightweight, inert flakes that fall harmlessly to the ground. The projectile is aimed and launched by a launcher to rapidly expel the projectile from a launching tube. Once in the air at a predetermined location in the sky, a fuse inside the projectile operates to detonate the projectile into its intended pyrotechnic display. The fuse is extremely accurate and enables detonation of the projectile at precise altitudes. An electronic control system controls launching and detonation of the projectiles in a precise and repeatable manner. The external geometry of the projectile also is configured so that the projectile tumbles when launched and follows a more predictable, repeatable and accurate path in flight.
