A Note of Appreciation for the MUS

摘要

This note has been written to acknowledge the pervasive impact the Method of Universal Slopes (MUS) has had on the design and development of the Space Shuttle Main Engine (SSME) through its use in material fatigue properties definition for component analysis. Included is a brief historical perspective describing propulsion system development leading up to the SSME, the need for fatigue analysis capability in the SSME design, the role that MUS played in meeting that need as a material modeling tool and the engine's subsequent successful operating history.
