This report documents the work performed under Phase II - Operational Comparison of Selected Extinguishants - of the Halon Replacement Program for Aviation for the Aircraft Engine Nacelle Application. Phase II is the second of a three-phase program to determine a replacement for Halon 1301 in aircraft engine nacelle applications. The objective of Phase II testing was to determine which of the selected extinguishing candidates, through a head-to-head comparison, was most effective in extinguishing fires in an engine nacelle. Of the 3 extinguishants tested, HFC-227ea, HFC-125, and CF3I. HFC-125 was selected based on its cold temperature distribution capability, and its "Halon 1301-like" flow and discharge behavior. |
