Pyrotechnic Gas Generators

Rapid & Reliable. When it comes to separation safety, there is no room for error. Our gas generators are a gas-producing pyrotechnic device – initiated by electro-explosive or mechanical percussion devices and ETLs.

Gas Generators (pressure cartridges) use pyrotechnic mixtures to produce hot gas for a multitude of applications. They can be mechanically, electrically or laser initiated. Upon receipt of an input stimulus, the propellant in the gas generator will ignite, emitting heat, hot particles and/or gas at a controlled rate to provide the necessary input to the next level assembly. PacSci EMC can tailor a design by incorporating propellant grains of various geometries and associative hardware features to meet needed pressure vs. time gas delivery requirements.


Used to pressurize and/or actuate flight control surface systems, they are also known as start cartridges, typically provide gas flow to spin a turbine as part of the starting sequence for turbojet engines. They may also be used to provide actuation pressure to control the rate of mechanical movement in mechanical actuation systems.
