Title: Cold Discharge of CF3I in a Simulated Aircraft Engine Nacelle
Published: January 01, 2001
Abstract: One of the potential candidates for halon 1301 replacement in aircraft engine nacelle and dry bay fire protection applications and fuel tank ullage inerting is trifluoroiodomethane (CF3I). Before CF3I can be considered as a potential drop-in replacement, several operational and technical issues must be addressed or re-examined. CF3I has a normal boiling point of ‹22 e dispersion of CF3I into air at temperatures down to ‹40 C may not be as effective as halon 1301, which has a normal boiling point of C. Although tests have been conducted at room temperature [1], no information on the discharge of cold CF3I into a cold ambient can be found in open literature. This research program, which is a continuation of the work that we have reported at HOTWC 2000 [2], is to examine this important aspect to assure that there is no deterioration in dispersion performance of CF3I under such conditions.
