The SmartBlades 2.0 project was funded by the Federal Ministry for Economic Affairs and Energy (BMWi) under the Funding number: 0324032.

The reference finite element model in which this dataset is based upon consists of a validated wind turbine blade model for this 20-meters blade:

Christian Willberg. (2020). Smartblades 2 finite element reference wind turbine blade model (1.1) [Data set]. Zenodo.

This dataset includes four finite element models of the SmartBlades 2.0 Rotor Blade, described below. All input files "*.bdf" were used in MSC Nastran version 2018.2 to generate the output files "*.h5".

1) SmartBlades2 Rotor Blade Model V02 Topology Update

Willberg, C. model updated with topology features in the trailing edge, and spar-web joint regions. Including additional strucutral and test sensor masses, and refined mesh of 50mm element size.

1A) Model incorporating a clamped root boundary condition and test sensor masses:

1B) Model incorporating a free-free boundary condition:

2) SmartBlades2 Rotor Blade Model V02b Sparweb Free Joint Variant

The V02 Topology Update model including RBE2 connections along the spar-web joints with decoupled rotation in the spanwise axis.

2A) Model incorporating a clamped root boundary condition and test sensor masses:

2B) Model incorporating a free-free boundary condition:
