wind turbine rotor design

A new sub-scale field-prototype design solution is developed to realize the dynamics, structural response, and distributed loads (gravitational, aerodynamic, centrifugal) that are characteristic of a full-scale large, modern wind turbine rotor. Prior …

The last few decades have seen a significant growth in wind turbine size and capacity. Due to larger rotors, blades experience higher loads and larger load fluctuations due to wind shear and turbulence. Reducing these extreme and fatigue loads of …

textlessptextgreatertextlessstrongtextgreaterAbstract.textless/strongtextgreater We examine the effect of rotor design choices on the power capture and structural loading of each major wind turbine component. A harmonic model for structural loading …

In this paper we present a study to explore the design space of aero-structural performance of extreme-scale wind turbine blades. Traditionally, aerodynamics of the wind turbine blades has driven the design of the blade, but with blades reaching …

This paper discusses the design, manufacturing, and planned testing of a scaled demonstrator turbine as part of the Segmented Ultralight Morphing Rotor (SUMR) project funded by the Advanced Project Research Agency-Energy. The scaled demonstrator …

With the increase in demand for and reduction in costs of clean energy, wind turbines offer a very promising solution. However, to make offshore wind energy one of the preferred sources of clean energy, there is a need to bring down the levelized …

This paper presents the structural design of a 21-meter 1/5th scale SUMR demonstrator (SUMR-D) blade, which was designed to replicate the full-scale behavior of a 104-meter SUMR13 initial blade rated at 13.2 MW. This is a challenging structural …

With the progression of novel design, material and manufacturing technologies, the wind energy industry has successfully produced larger and larger wind turbine rotor blades while driving down the levelized cost of energy (LCOE). Though the benefits …
