Abstract

Until recently halon 1301 has been regularly discharged in Navy aircraft engine nacelles to certify that the fire suppression systems distribute the fire suppressant effectively. Halon 1301 can no longer be used in this manner because of its high ozone depletion potential. In order to continue to certify the fire suppression systems of Navy aircraft a surrogate for halon 1301 must be found. Ideally, this stimulant will have the physical and dynamical properties that will allow it to mimic halon 1301 in discharge behavior in any aircraft fire suppression system. This work presents the significant parameters relevant to agent discharge in an engine nacelle, as well as a discussion of the procedure and preliminary results of our search for a halon 1301 simulant.
