SELECTED THERMODYNAMIC AND FLUID FLOW DATA FROM THE SPACE SHUTTLE LIQUID OXYGEN SERVICING SYSTEM

This paper presents some thermal/flow data from the Space Shuttle liquid oxygen servicing system which consists of a 3408 m3 storage tank and a 15.24-centimeter vacuum-jacketed transfer line of about 500 meters long. The flowrate, pressure, and temperature data cover the system chill down and the stable flow. The pressure spike data are due to liquid column separation and vapor cavity collapse. Procedures associated with these data are given in details such that computer models for cryogenic system performance and waterhammer analyses can be validated.
