Electrothermal chemical firework launching device and method

Abstract

The invention provides an electrothermal chemical firework launching device and method. The launching device comprises an electrothermal chemical firework bomb, a launcher and a discharging loop; the electrothermal chemical firework bomb is composed of a cartridge case, a plasma generator, an ablation material and firework projectiles, the launcher is composed of a body tube, a supporting system and a cartridge chamber, and the discharging loop is composed of a pulse power supply, a primary energy source and a high-voltage cable. Through adjustment of the waveform and amplitude of the pulse current generated by the pulse power supply, the temperature and pressure of the plasma generated by the plasma generator are controlled, so that different doing capacities are obtained, different launching initial speeds of the firework projectiles can be accurately obtained, the firework projectiles can reach the preset launching height needed by fireworks, the controllability of the firework launching height and launching direction can be enhanced, meanwhile, impact damage to firework projectiles in the launching process can be reduced, the firework launching precision and the mechanical rigidity of the firework launching device can be improved, and it is guaranteed that fireworks with specific characters or patterns are achieved according to the design effect.

Description

technical field [0001] The invention belongs to the technical field of fireworks discharge, and in particular relates to an electrothermal chemical fireworks launching device and method. Background technique [0002] In recent years, special effects fireworks with specific characters and patterns have become an indispensable link and a highly anticipated highlight of grand events held in my country. Although my country's special-effect pyrotechnic launch technology is at the forefront of the world's pyrotechnic technology field, there is still a lot of room for improvement in the accuracy and height control of fireworks launch. [0003] At present, many fireworks bombs still use explosives instead of gunpowder to provide firing power, which leads to the extreme characteristics of high first and then low pulse in the chamber pressure curve. The high chamber pressure has a serious impact on the barrel, and the high chamber pressure pulse work efficiency is low. Under the high...
