An ignition device suitable for simultaneous ignition of multi-channel pyrotechnic products

Abstract

The disclosure provides an ignition device suitable for simultaneous ignition of multi-channel pyrotechnic products, including: a charging power supply, a charging control module, a capacitive energy storage module and an ignition execution module, the charging power supply, the charging control module and the The capacitive energy storage modules are connected in series, and the capacitive energy storage module and the ignition execution module are connected in parallel; the beneficial effect of the present disclosure is that a large-capacity capacitor bank is used as an energy storage device, which has the characteristics of high energy density and fast charging and discharging. It can output a large current of hundreds of amperes instantaneously. There are three levels of safety control. Through the series-parallel design, the three-level control layer solves the safety, which can not only ensure the reliable ignition of pyrotechnics, but also prevent false triggering and ensure safety. The ignition device involved in the present disclosure can conveniently expand the capacity of the energy storage module and the number of ignition channels according to the specific requirements of the number of channels of pyrotechnic products, so as to provide a larger instantaneous output current and meet the ignition requirements of more channels of pyrotechnic products. .

Description

technical field [0001] The disclosure relates to the technical field of pyrotechnics, in particular to an ignition device suitable for simultaneous ignition of multi-channel pyrotechnic products. Background technique [0002] Pyrotechnics are widely used in civilian and military fields. They are small sensitive explosives filled with explosives. In the aerospace and military fields, they are mostly used for rocket or missile engine ignition, compartment separation, and warhead detonation. The ignition device of the pyrotechnic product can output a certain power of electric energy to heat the resistance bridge wire of the pyrotechnic product, thereby detonating the ignition explosive. [0003] In the existing rocket pyrotechnic ignition technology, the ignition device is mostly composed of batteries, electromagnetic relays, etc., which can complete the ignition of 1 to 4 channels of pyrotechnics at a time, and the application is very mature. [0004] With the development and...

AI Technical Summary

Problems solved by technology

Generally speaking, when multiple channels of pyrotechnics need to be detonated at the same time, the instantaneous current required is very large, and a large-capacity battery is required to have the instantaneous high-current output capability, and the use of a large-capacity battery will greatly increase the weight and weight of the system. Volume, which is difficult to meet the application scenarios with strict restrictions on weight and volume

For the application scenario where multiple engines are connected in parallel and multi-channel pyrotechnic products are ignited at the same time, the existing ignition device cannot meet the requirements of light weight, miniaturization and instantaneous high energy density at the same time
