- Abstract
- The work discussed in this paper is part of a larger effort at NIST focused on finding an alternative to halon 1301 for application to aircraft engine nacelle and dry bay in-flight fire protection. Alternative chemical compounds are sought which will perform similarly to halon 1301, and whick do not create unacceptable safety, environmental, or systems compatibility problems. A cup burner, an opposed flow diffusion flame, a turbulent spray flame, and a deflagration/detonation tube are being used to rank the relative combustion suppression effectiveness of the following agents: R-32 (CH₂F₂), R-32/R-125 (CH₂F₂/CHF₂CF₃), HFC-227 (C₃HF₇), R-22 (CHF₂Cl), HFC-134a (CH₂FCF₃), FC-116 (C₂F₆), HCFC-124 (CHFClCF₃), R-125 (CHF₂CF₃), FC-218 (C₃F₈), FC-31-10 (C₄F₁₀), and FC-318 (cyclo-C₄F₈). Table 1 lists the fuels and agents to be evaluated and the experimental variables for each configuration.
