Investigation of Innovative Rotor Concepts for the Big Adaptive Rotor Project
The Big Adaptive Rotor (BAR) project is funded by the U.S. Department of Energy (DOE) Wind Energy Technologies Office and has the objective of researching and developing innovative technologies that enable large land-based rotors that have the potential to produce a 10% increase in CF over current technology. The innovative technologies must have a reduction in specific power to at least 150 W/m2 at an International Electrotechnical Commission Class III wind site for a 5-megawatt (MW) or higher rating and maintain a competitive levelized cost of energy (LCOE) compared to current technology. The purpose of this document is to: 1. Identify and classify innovative BAR concepts, 2. Evaluate the concepts in terms of their potential to impact wind plant LCOE and other performance metrics of interest and identify science and engineering challenges that would limit the commercialization of these concepts, and 3. Quantitatively analyze and compare the BAR concepts.
