3 Terms and definitions

The following terms and definitions defined in GB/T 32455 and GB/T 19000 apply to this document.

3.1 Explosivesystem

When the ignition system receives the work order, it generates a bunch of ignition pulses, which are applied to the first pyrotechnic device of the explosion sequence to trigger the explosion fire

The work product causes a series of effects in the explosion sequence, and finally generates the explosion energy output, drives the terminal device to work, and completes the function of the predetermined task.

Note. The aerospace pyrotechnics system consists of three parts. ignition system, explosion sequence and terminal device. Among them, work instructions are presented in the form of electrical energy, light energy or mechanical energy.

The connection relationship of the pyrotechnic system is shown in Figure 1.

3.2 Firingsystem

The control system inputs power supply, instructions and control, and these input information is converted into electrical energy, light energy or mechanical energy output, thereby initiating an explosion
