An efficient blade sweep correction model for blade element momentum theory
Wind Energy, 2022 This article proposes an efficient correction model that enables the extension of the blade element momentum method (BEM) for swept blades. Standard BEM algorithms, assuming a straight blade in the rotor plane, cannot account for the changes in the ...

A CFD‐based analysis of dynamic induction techniques for wind farm control applications
Wind Energy, Volume 26, Issue 3, Page 325-343, March 2023., 2023 Summary Recently, dynamic induction control is gaining the interest of the wind energy community as a promising strategy to increase the overall wind farm power production. Such a technique is based on a dynamic variation of the upstream rotor thrust, generated through a suitable blade pitch motion, to promote a faster wake recovery.

Aeroelastic Tailoring of Helicopter Blades
Volume 7A: 9th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2013 The dynamic loads transmitted from the rotor to the airframe are responsible for vibrations, discomfort and alternate stress of components. A new and promising way to minimize vibration is to reduce dynamic loads at their source by performing an aeroelastic optimization of the rotor.
