Abstract:
The amount of a gaseous agent required to extinguish
fires in full-scale engine nacelle tests varies greatly
with the geometry of the fixture and the manner in which
the flame is stabilized. It has been observed that if
the test is designed to allow fuel to collect behind
obstacles in the vicinity of a hot surface, a
significantly higher mass of agent is necessary for
sustained suppression. The superior performance of
chemically acting agents such as CF3Br and CF3I relative
to a hydrofluorocarbon alternative like HFC-125 is also
accentuated in some of these tests. Full-Scale testing
carried out by the Navy using two different fixtures,
each meant to simulate fires in the F/A-18 engine
nacelle, has led to different conclusions regarding the
amount and relative performance of both HFC-125 and
solid propellant gas generator (SPGG) fire suppression.
