| 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. | ||||||
