Pyrotechnic Through Bulkhead Initiator (TBI)
Pyroalliance designs and manufactures a series of Through-Bulkhead Initiators (TBI) for defense applications.
TBIs are designed to convert a detonating input into an ignition function, typically to ignite the propellant of a Solid Rocket Motor. Tightness is guaranteeed between upstream and downstream side of bulkhead, preventing any loss of pressure.
TBIs are a key component of the propulsion function reliability and safety. Combined with other products from Pyroalliance, TBIs are part of pyro-chains for Solid Rocket Motors.
More generaly, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs. They are designed and manufactured under Pyroalliance design authority.
Through Bulkhead Initiator at a glance
Benefits of pyrotechnics
- An ignition function with detonating input
- Structural barrier preventing loss of pressure of downstream elements
- Mass savings through the reduced quantity of embedded electrical power
- Absence of primary explosives (making one single Safe & Arm Device at the beginning of the pyrotechnic chain sufficient)
- Reduced dispersion of ignition times
- High level of safety (EMC and lightning immunity)
- Architecture without any moving parts
Defence applications
- Ignition of single pulse solid propellant motors
