Aero-Structural Design For a 3.4 MW Wind Turbine Using Plasma Actuator Based Load Control

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 …

Aero-Structural Design Study of Extreme-Scale Segmented Ultralight Morphing Rotor Blades

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 …

Flutter Predictions in the Design of Extreme-Scale Segmented Ultralight Morphing Rotor Blades

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 …

Structural Design of a 1/5th Scale Gravo-Aeroelastically Scaled Wind Turbine Demonstrator Blade for Field Testing

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 …

Assessment of flutter prediction and trends in the design of large-scale wind turbine rotor blades

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 …
