BAR Designs
Top level git repo for the wind turbine designs developed under the BAR project. The repo hosts the OpenFAST aeroservoelastic models and the corresponding yaml files following the WindIO ontology https://windio.readthedocs.io/en/latest/
The designs are described in the following publications:
-
Land-based wind turbines with flexible rail-transportable blades – Part 1: Conceptual design and aeroservoelastic performance. Pietro Bortolotti, Nick Johnson, Nikhar J. Abbas, Evan Anderson, Ernesto Camarena, and Joshua Paquette. Wind Energ. Sci., 6, 1277–1290, https://doi.org/10.5194/wes-6-1277-2021, 2021
