“…As for why MI10 seems to under-perform when compared to the others, this is likely Sample set size because the changes to the global eigenfrequency induced by scaling all elements by 10% can lead to dynamic amplification for lower wind speed load cases when the frequency increases (corresponding to the structure being scaled up). In this particular situation, there is a significant shift towards the 3P frequency of the turbine, as seen from the Campbell diagram of the NREL 5MW turbine (Jonkman and Jonkman, 2016). The result is a significant increase in the severity of lower wind speed load cases, which means that the error in including only the most severe load cases in the fatigue estimation changes more drastically for 5 this design.…”

“…The turbine and support structure models used in this study are the NREL 5MW turbine and the OC3 monopile, respectively. The time domain analysis has been performed using the fully integrated aero‐elastic software FEDEM Windpower .…”

“…To validate the FE model utilized, a reliable modal test result for a single blade with the same structural configuration is required; to the authors' knowledge, there is no reliable modal analysis result for a single blade of the NREL 5MW baseline wind turbine. In relation to NREL 5MW wind turbine modal parameters, the available data from [15,23,26,27] can be considered. However, most of the available data for modal parameters of the NREL 5MW turbine are the results of a full-system analysis, including the blades, drivetrain, nacelle, and tower.…”

“…Assessing Figure 8 and the modal frequencies for each mode, the frequencies of the FE model and LMH64-5 blade are closer for the 1st, 2nd and 4th mode but a significant difference is seen in the third mode, i.e., the 2nd flapwise mode. Another justification for the FE model can be drawn from the Campbell diagram of the blade given at Figure 9; the trend of the modal frequency with the rotor speed can be fairly considered to be similar to the reference blade [26].
