摘要

The Propulsion Research Center at the University of Alabama in Huntsville is developing a liquid oxygen system for the testing and evaluation of cryogenic components. The preliminary design assessment for the new system used oxygen compatibility assessments and hazard analyses to lower the operational risk. The purpose of this effort was to build upon previous work and to contribute to the standardization of safe oxygen practices at the Propulsion Research Center. This paper details the preliminary design assessment of the liquid oxygen component test system from the perspective of oxygen safety, cryogenic hazards, and test conditions. The major oxygen safety considerations used in the assessment of the system were material compatibility and ignition risks. This effort details the criteria used to determine the materials selected for the system and the use of materials to break kindling chains. The system was reviewed to take into consideration ignition risks due to the components used and system layout with changes being implemented to lower the inherent risk of system operation. The system was also analyzed to evaluate its compatibility with cryogenic hazards and its ability to meet the required test conditions. The results detailed in this paper represent the implementation of safe oxygen practices at the Propulsion Research Center.
