Solution for the problem of metallization within structure of high pressure solid propellant gas generator

Abstract

A gas generator is a device which is sensitive for electrical discharge caused by electrostatic charges. When nipple connection of initiation unit and gas generator lid is used the metallization is provided through cone surfaces contact of the units to be mated. This way of metallization is optimal when operational conditions are regulated strictly. In order to make gas generator operational requirements less strict and enhance operational safety the gas generator structure was changed (i.e., way of metallization).
