Pyroalliance designs and produces a series of Through-Bulkhead Initiators (TBI) for the European Ariane and Vega launcher families.
TBIs are designed to ignite the propellant in a solid rocket motor and also guarantee tightness after functioning between upstream and downstream side of bulkhead, preventing any pressure loss.
They are a key component of the propulsion function reliability/safety. TBIs belong to a pyrotechnic chain which ensures transition from a detonating signal stemming from a detonating transfer line into the combustion of an ignition load, across a tight barrier.
TBIs, combined with other Pyroalliance’s products, are part of Ignition pyro-chains for solid rocket motors or retro-rockets. They are designed and manufactured under Pyroalliance design authority
