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.

Rocket Motor Igniters are used to ignite solid rocket motors or liquid fueled rocket engines.

PacSci EMC’s rocket motor igniters are used on multiple missile and space vehicle platforms, including:

  • Delta IV, Main Engine (RS-68) Igniter
  • Delta IV, Gas Generator Igniter (RS-68)
  • Antares (Taurus II), Main Engine (AJ26-62)
