How Rocket Motor Igniters Work

A Rocket Motor Igniter provide the necessary heat source to ignite rocket engines. A rocket motor igniter utilizes an electrical input stimulus that ignites an Electro-Explosive Device (EED), which in turn ignites a propellant grain. The propellant grain is designed to sustain a controlled burn to emit the necessary heat and hot particles for sufficient time to reliably ignite a rocket motor. PacSci EMC can tailor the burn duration to meet customer’s performance specification requirements. They can be customized to burn for a specified period of time, based on the application. PacSci EMC has manufactured millions of igniters over its lifetime, proven highly effective in a diverse set of applications.
