Composite Turbine Blade Design Options for Claude (Open) Cycle OTEC Power Systems

    Research output: NRELTechnical Report


    Small-scale turbine rotors made from composites offer several technical advantages for a Claude (open) cycle ocean thermal energy conversion (OTEC) power system. Westinghouse Electric Corporation has designed a composite turbine rotor/disk using state-of-the-art analysis methods for large scale (100-MW) open cycle OTEC applications. Near-term demonstrations using conventional low-pressure turbineblade shapes with composite material would achieve feasibility and modern credibility of the open cycle OTEC power system. Application of composite blades for low-pressure turbo machinery potentially improves the reliability of conventional metal blades affected by stress corrosion.
