PSEMC
produces a wide variety of explosive actuated Hot Gas
Initiators (HGI). These units produce various
pressure outputs adapted to specific customer requirements and
have an operating temperature range of -65° F to +200° F.
These units are activated from a detonation input signal
from a Shielded Mild Detonating Cord (SMDC) assembly.
The detonation of the input SMDC deforms an integral bulkhead
to drive a firing pin into a dual percussion primer cartridge.
The primers ignite a pickup charge which in turn initiates the
propellant charge. The combustion products provide the gas
pressure to the hose configuration coupled to the out put port.
The cartridges are qualified as separate items per MIL-D-21625
and the entire assembly to MIL-D-23610. Units of this type, such
as the Explosive Actuated Hot Gas Initiators, are fully qualified
for utilization on aircraft platforms such as the B-1B,
F-15 and F/A-18.
