L08 - IEA 10MW RWT |

This example considers the IEA 10 MW reference wind turbine and recreates the model in Flexcom. Full details of the turbine are provided in the official definition document (Bortolotti et al., 2019) while some of the main aspects are briefly summarised here.
The results section presents a brief summary of a code-to-code comparison of simulation models built using OpenFAST and Flexcom. As the study is focused on the aeroelastic response, the turbine is fixed at its base, and no hydrodynamic effects are considered.
The turbine was developed to have a rated electrical power of 10 MW, and designed for the IEC class 1A, and features a direct-drive generator. It has a rotor diameter of 198 m and a hub height of 119 m.
The IEA 10 MW RWT data is open source and is available on the IEA Wind Systems GitHub site IEA Wind Systems GitHub. Aero-servo-elastic input files to model the turbine in various modelling tools are also available in the repository.
