Embodiment Construction

[0018] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] This embodiment proposes a recoilless fireworks launching device using an electromagnetic recoil mechanism, and its structure is as follows: figure 1 As shown, it mainly includes barrel 4, movable powder chamber 3, breech mechanism and electromagnetic brake (comprising stator 2 and movable magnet 1).

[0020] The barrel 4 is a metal tube, which is made by adding an expansion-type Laval nozzle at the rear of the cylindrical barrel, and serves as the structural main body of the entire launching device. The barrel 4 is connected with the support system through the trunnion, and the support system provides stable structural support and determines the shooting direction for the entire launching device.

Abstract

The invention provides a recoil-free firework launching device adopting an electromagnetic counter-recoil mechanism and a firework bullet launching method. The launching device comprises a barrel, a movable powder chamber, a breech mechanism and an electromagnetic brake. According to the invention, rapid opening of a nozzle under different pressures is implemented by adjusting the electromagnetic resistance, the latch opening time and the closing time of pressure relief of a chamber pressure are controlled to adjust the tail jet flow pressure to implement initial speed control, and the launching height and the launching speed are controlled by controlling the bullet chamber exiting speed. According to the invention, the launching height and the launching speed can be controlled only by adjusting the current and the voltage which are input into the electromagnetic brake, impact damage to firework bullets in the launching process is reduced, the firework launching precision and the mechanical rigidity of the firework launching device are improved, and specific character or pattern fireworks are guaranteed to be implemented according to the design effect.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a recoilless firework launching device and method for controlling the firing time and adjusting the firing kinetic energy of projectiles through an electromagnetic re-entry mechanism to control the firing height and firing speed. 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 cur...
