Retractor
Pyroalliance designs and manufactures pyrotechnic pin retractors dedicated to secure the holding position of a mechanism aiming to be deployed or ejected after the pin is retracted.
This is often the case on missiles, for flight surface actuators, wings or air intake cover. The overall dimensions as well as piston travel ranges are adjusted depending on the application.
The pin retractors are triggered at various moments during the full sequence of a mission.
More generally, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs. They are designed and manufactured under Pyroalliance design authority.
