SmartBlades 2.0 Rotor Blade Nastran Models

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. https://doi.org/10.5281/zenodo.4604693 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: Input: SmartBlades2_Rotor_Blade_Nastan_Model_V02-Topology_Update-Root_Clamped.bdf Output: SmartBlades2_Rotor_Blade_Nastan_Model_V02-Topology_Update-Root_Clamped.h5 1B) Model incorporating a free-free boundary condition: Input: SmartBlades2_Rotor_Blade_Nastan_Model_V02-Topology_Update-Free_Free.bdf Output: SmartBlades2_Rotor_Blade_Nastan_Model_V02-Topology_Update-Free_Free.h5 <br> 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: Input: SmartBlades2_Rotor_Blade_Nastan_Model_V02b-Sparweb_Free_Joint-Root_Clamped.bdf Output: SmartBlades2_Ro tor_Blade_Nastan_Model_V02b-Sparweb_Free_Joint-Root_Clamped.h5 2B) Model incorporating a free-free boundary condition: Input: SmartBlades2_Rotor_Blade_Nastan_Model_V02b-Sparweb_Free_Joint-Free_Free.bdf Output: SmartBlades2_Rotor_Blade_Nastan_Model_V02b-Sparweb_Free_Joint-Free_Free.h5<br> General data of the blade (from https://elib.dlr.de/131955/1/AG_FVW_in_der_Windenergie_191024_Stueve.pdf) Diameter of the rotor 46.61m Nominal rotational speed 37.1 rpm Length of rotor blade 19.99 m Maximum chord length 2.38 m Max. pre-bend 1 m Surface of main shell 69.8 m² Blade nominal mass Fiber mass (dry) 889.5 kg Infusion Resin 579.3 kg Bonding Resin 44 kg Other materials (e.g. Foam) 80.5 kg Extra masses (e.g. Sensors) 123.4 kg Total mass of the blade 17168 kg
