Abstract:

Properties of ten compounds which have passed screening for possible use in the in-flight fire extinguishing system of the Supersonic Transport are tabulated. Reported are boiling points, freezing points, densities, viscosity- temperature relationships, vapor pressure-temperature curves, critical temperatures and pressures, heats of vaporization, specific heats pressures at 500 F and thermal stabilities under testing conditions. Also reported are the inhibitory effects of each compound on heptane-air flammabilities, estimated costs and compatibilities with various metallic and non metallic materials. Potential toxicities are discussed. Limited physical properties of an additional twenty-four materials which did not pass this preliminary screening are tabulated. Recommendations are given for more extensive work on acceptable compounds to further define their usefulness under Supersonic Transport flight conditions.
