Advanced Expander Test Bed Program

Abstract

The Advanced Expander Test Bed (AETB) is a key element in NASA's Exploration Technology Program for development and demonstration of expander cycle oxygen/hydrogen engine technology component technology for the next space engine. The AETB will be used to validate the high-pressure expander cycle concept, investigate system interactions, and conduct investigations of advanced mission focused components and new health monitoring techniques. The split- expander cycle AETB will operate at combustion chamber pressures up to 1200 psia with propellant flow rates equivalent to 20,000 lbf vacuum thrust. Effort during 1990 focused on: (1) definition of the key methodologies to be applied to the test bed design and to be verified as part of the AETB program; (2) development of transient and steady state AETB models; and (3) preparation of the AETB preliminary design.
