Through Bulkhead Initiators (TBI)
Pyroalliance designs and produces a series of Through-Bulkhead Initiators (TBIs) 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 guaranteed 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 generally, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs.
They are designed and manufactured under Pyroalliance design authority.

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
