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 …

This technical report describes the design of a new 22 Megawatt reference wind turbine
(RWT). The turbine model was designed collaboratively by two teams at the Denmark …

This paper presents a novel model order reduction technique for 3D flexible multibody
systems featuring nonlinear elastic behavior. We adopt the mean-axis floating frame …

This work presents an integrated multidisciplinary wind turbine optimization framework
utilizing state-of-the-art aeroelastic and strutural tools, capable of simultaneous design of the …

While most wind energy comes from large utility-scale machines, small wind turbines
(SWTs) can still play a role in off-grid installations or in the context of distributed production …

For measurements taken over a decade at the coastal Danish site Høvsøre, we find the
variance associated with wind speed events from the offshore direction to exceed the …

The variability of the wind turbine loads complicates fatigue assessment in the design
phase, as performing simulations covering the entire lifetime is computationally expensive …

Mitigating loads on a wind turbine rotor can reduce the cost of energy. Sweeping blades
produces a structural coupling between flapwise bending and torsion, which can be used for …

Local buckling is one of the key driving forces of trailing edge failure in composite wind
turbine blades. This study demonstrated a significant stiffness increase by adding a minor …

In optimal wind turbine design, there is a compromise between maximizing the energy
producing forces and minimizing the absolute peak loads carried by the structures. Active …
