SAFRAN Pyroalliance is a European producer of energetic equipment: design, production and marketing of a wide range of equipment to meet the demanding specifications of aerospace, defense and industry. These energetic equipments perform a number of critical functions, including launch, propulsion, flight control and range safety.

SAFRAN Pyroalliance is a subsidiary of Herakles (Safran group).

It has built up expertise in the technologies needed to convert energy from an energetic material (grain, propellant, explosive) into a function or combination of functions. These functions generally involve a mechanical action (push, pull, inflate, cut, release, etc.), or the transmission of a command (ignite, separate, supply a fluid, generate a gas or thrust). A complete function can be performed by coupling different assemblies (ignition and safety, command transmission, terminal functions such as ignition or a mechanical action).

Pyrotechnic technologies offer a number of advantages over conventional electromechanical, pneumatic or hydraulic systems:

• Significant energy developed in a controlled time (from less than a millisecond to several seconds).
• Low triggering energy (mechanical or electric).
• Smaller and lighter.
• Very high reliability, security and availability.
• Little or no maintenance over lifetime.
• Operating time compatible with need for simultaneous or synchronized requirements.
• Robust resistance to external hazards (vibration, shock, electrostatic discharge, electromagnetic, thermal, etc.).
