Implementation of the blade element momentum model on a polar grid and its aeroelastic load impact
Wind Energy Science, 2019 . We show that the upscaling of wind turbines from rotor diameters of 15–20 m to presently large rotors of 150–200 m has changed the requirements for the aerodynamic blade element momentum (BEM) models in the aeroelastic codes.

Structural Design, Analysis, and Testing of a 10 kW Fabric-Covered Wind Turbine Blade
Energies, 2020 Reducing the weight of a wind turbine blade is a major issue. Wind turbines have become larger in size to increase power generating efficiency. The blade has also grown in length to take more wind energy.

Influence of blade-to-blade dissimilarity on alleviation of helicopter blade-vortex interactions
Mathematical and Computer Modelling, 2001 This paper numerically examines possible alleviation of parallel blade-vortex interaction (BVI), experienced by helicopters in low-speed descent, through the introduction of blade-to-blade dissimilarity. A four-bladed rotor with two sets of opposite blades is considered, and the radius of one set is reduced to 80% of the baseline radius.

Influence of blade aerodynamic model on prediction of helicopter rotor aeroacoustic signatures [PDF]
, 2011 Brown’s vorticity transport model has been used to investigate how the local blade aerodynamic model influences the quality of the prediction of the high-frequency airloads associated with blade–vortex interactions, and thus the accuracy with which the ...
