Testing of an Advanced Liquid Hydrogen Turbopump

Abstract

This paper discusses the testing of an Advanced Liquid Hydrogen Turbopump for a 50,000 pound (222.4 kN) thrust Upper Stage Expander Cycle Engine being developed by Pratt & Whitney Liquid Space Propulsion under contract to the United States Air Force Research Laboratory (AFRL) to support the Integrated High Payoff Rocket Propulsion Technology (IHPRPT) program. The Advanced Liquid Hydrogen (ALH) Turbopump is designed to provide improved system thrust to weight decreased hardware/support costs, and increased reliability. These benefits will be demonstrated through test of this high speed, high efficiency, two stage hydrogen turbopump.
