Title A design of the multi-function ignition installation of the initiating explosive devices
Abstract
Initiating explosive devices ignition is an important process of the missile launch. The multi-function ignition installation is used to control the ignition, provide high current, provide trigger signal to external equipment and ensure ignition safe.
This paper firstly classifies the current ignition installation and introduces an ignition installation based relays. The installation includes the measurement and display of the circuit resistance, trigger signal output, constant large current source design, automatic ignition,
stop, protection when less power and so on.
This paper designs various parts of the installation, shows the circuit and PCB picture, and tests the installation.
Keywords Initiating Explosive Devices Resistance Measurement
