High-Pressure Liquid and Gaseous Oxygen Impact Sensitivity Evaluation of Materials For Use At Kennedy Space Center.
Abstract
Many materials will ignite or explode when in contact with gaseous oxygen (GOX) or liquid oxygen (LOX) if subjected to stimuli such as a mechanical impact, adiabatic compression (pneumatic impact), or an electrical discharge in the form of a spark. Such materials must therefore be characterized as to compatibility with LOX or COX to define the degree of hazard with their use. Generally, materials are more sensitive in gaseous oxygen than in liquid oxygen and impact sensitivity is known to increase with increasing pressure. Thus, the evaluation of the sensitivity of materials in GOX is required to supplement LOX impact test data. The testing program described in this report was initiated to evaluate materials presently being used or considered for use in oxygen systems at KSC. The ambient pressure LOX testing phase of this program was performed at KSC, the pressurized LOX testing at MSFC, the COX mechanical impact testing at MSFC and WSTF, and the flash and fire point and pneumatic impact testing at WSTF.
