Actuator
Pyroalliance designs and manufactures pyrotechnic actuators involved in the deployment or the retracting of a piston for military systems.
A typical application is for missiles for which actuators are involved in the deployment of flight surfaces.
The overall dimensions as well as piston stroke are adjusted depending on the application. Different actuators are possibly triggered at various moments of the mission’s sequence.
More generally, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs. They are designed and manufactured under Pyroalliance design authority.

Benefits of pyrotechnics
- High speed of operation (from 10ms but can be adapted to load case though a damping system)
- High reliability level (≥ 0,9998 @90% CL) and no required maintenance
- Hermeticity : contained effects, no fragments or flames
- High security level with locking system preventing from unexpected operation and structure margins designed to resist to extra loads
Defence applications
- Missile fins or wings deployment
- Missile tube ejection
- Emergency door release
