Abstract : Data are presented defining thermal stability limits for model structures of fluorinated chloro- and bromo-carbons suitable for use as fire extinguishing agents. Heating analyses have been made for an idealized extinguishant tank subjected to various flight regimes. Insulation thicknesses as well as example calculations of weight penalties due to insulation necessary to maintain temperatures below decomposition have been computed for various extinguishants in the idealized tank under Mach 4 and 5 regimes. A literature survey and study of the feasibility of using dry powder extinguishants as in-flight extinguishants has been made. Problems which may be encountered are discussed. (Author)
