Main propulsion system test simulator project

In the past, only component and subsystem testing was available during development. Full-scale propulsion system testing was performed for final verification using specialized test articles and test facilities. Following test program completion, the test article was discarded and the test facility deactivated. This left operational systems with no test bed to support anomaly simulation and evaluation. This paper discusses an approach that would provide large scale propulsion system testing for both new system design and development, and of the operational Space Shuttle main propulsion system.
