Abstract:
This is the fourth in a series of reports on the fire and explosion hazards associated with combustibles and other gases likely to be found in aircraft and missile systems. It presents experimental results pretinent to inhibition of gaseous detonation, ignition of solid oxygen-liquid hydrogen mixtures, and flammability characteristics of halogentaed hdrocarbons.The halogentaed hydrocarbons do not appear to be particularly effective inhibitors of gaseous hydrogen-oxygen detonation. Combustion such as methan and hydrogen were found to be superior to the halogenated hydrocarbons on a weight basis.Cryogenic mixtures of solid oxygen and liquid hydrogen can be ignited by 0.5-ounce projectiles moving as low as 1310 ft/sec (400 meters/sec). Ignition appears to occur at shock strengths of 1.5 to 3.0 kilobars.Although the halogentaed hydrocarbons considered here do nopt appear to be flammable in air at atmospheric pressure and ordinary temperatures, some are flammable in oxygen under these conditions. Flame speeds and maximum explosion pressures associated with the flammable mixtures were found to be considerably lower than those of the corresponding hydrocarbon-oxygen mixtures.
