Sandia rotor innovation activities are directed primarily toward two approaches
1) Quantitative evaluation and reporting of rotor innovation concepts using numerical studies. Examples include the Sandia 100m blade design progression and the Sandia investigation of the effects of increasing maximum tip velocity on optimum rotor designs. Complete and accurate numerical design methods are critical to our work in this area. Projects result in public, detailed models and tools that are beneficial to the entire wind energy research community.
2) Design and field test of rotor hardware for validation of rotor innovation concepts or hardware created to support goals of larger experimental campaigns, such as the DOE Atmosphere-to-electrons (A2e) Initiative. Work in this area leads to public field test data which is used to improve important simulation and analysis tools, enabling effective evaluation of future innovations.
