Abstract
A Component Test Facility (CTF) is presently under construction at NASA’s Stennis Space Center (SSC) in Mississippi to test high-pressure turbopump assemblies. These high-pressure pumps will deliver fuel and oxidant to the Advanced Launch System (ALS) main and booster engines to provide greater thrust and thus deliver heavier payloads into orbit. Liquid hydrogen and liquid oxygen pumps will be tested in the CTF for 25 seconds “steady state” duration.
The turbine-driven test pumps will deliver the cryogens in the 41368 kPa (6000 psi) to 55158 kPa (8000 psi) range. Three test cells, one for oxygen and two for hydrogen turbopumps, each contain a gas generator, a turbine, and a pump. Ultrahigh-pressure (UHP) gas systems at 103420 kPa (15000 psi) will be used to pressurize and move the cryogenic fluids to the test cells. While the fluids to the test cells must flow at defined steady state conditions for the short duration of the test, the delivery system is in a state of change throughout a test run. The challenge was to provide one set of controls and equipment to handle the unsteady state fluids and deliver steady state fluids to the test cell.
