A test program was performed to determine the highest pressure in oxygen where materials used in the planned NASA Constellation Program Orion Crew Exploration Vehicle (CEV) Crew Module (CM) would not propagate a flame if an ignition source was presen

The sources of variability in the pneumatic impact test commonly used to screen nonmetallic materials for oxygen service and to rank batches or lots of particular materials were investigated together with the mechanism of ignition. Tests were conduct

The ignition of oil-film contaminants in high-pressure gaseous oxygen systems, caused by rapid pressurization, was investigated using the NASA/White Sands Test Facility's large-volume pneumatic impact test system. The test section consisted of stainl

Publisher Summary Fire is a very serious threat in any confined volume but particularly is so when a crew is confined in a spacecraft far from Earth, where there is little or no possibility to receive aid or be rescued. Therefore, every measure must

Publisher Summary Oxygen is a powerful oxidizer in both gaseous and liquid states, and its use involves a degree of risk that should never be overlooked. Oxygen is reactive at ambient conditions, and its reactivity increases with increasing pressure,
