Abstract:

This report describes the results of an advanced composite-rotor mechanical-design-feasibility study program. Four advanced composite fan-rotor concepts and one composite reinforced compressor-rotor concept were evolved and evaluated during this study. One particular fan concept, titled pinned-bladehoop rotor, received extended evaluation because it allowed the replacement of blades and showed a significant weight and cost advantages over the metal counterpart. This concept was applied to both a subsonic-flight engine and a supersonic-flight engine for potential future development. Author
