Advanced Expander Test Bed Program. Preliminary Design Review Report

Abstract

The Advanced Expander Test Bed (AETB) is a key element in NASA's Space Chemical Engine Technology Program for development and demonstration of expander cycle oxygen/hydrogen engine technology and 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 preliminary design 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 of major components and systems.
