Wind turbine rotor blade monitoring using digital image correlation: a comparison to aeroelastic simulations of a multi-megawatt wind turbine [PDF]
, 2014 Optical full-field measurement methods such as Digital Image Correlation (DIC) provide a new opportunity for measuring deformations and vibrations with high spatial and temporal resolution. However, application to full-scale wind turbines is not trivial.

Analysis of Wind Turbine Blade [PDF]
International Journal of Current Engineering and Technology, 2010 Blades are the most critical component of a wind turbine which is responsible for conversion of wind energy into kinetic energy. Aerodynamics is a science and study of physical laws of the behavior of objects in airflow and the forces that are produced by airflows. In the early stage, the research on wind turbine blade design was limited on theoretical

Wind turbine noise modeling: prediction of amplitude modulation and influence of atmospheric conditions [PDF]
, 2014 International audienceAeroacoustic noise from a wind turbine is mainly caused by the interaction between the wind turbine blade and the air flow. For a modern wind turbine, trailing edge noise is often the dominant noise source. In this paper, a detailed

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

The Concept of a Smart Wind Turbine System [PDF]
, 2007 The concept of a smart wind turbine with telescopic blades was analyzed using a mathematical model based on the blade element – momentum theory. The telescopic blade concept uses the idea of extending the turbine blades when wind speeds fall below rated ...

Prediction of Cure‐Induced Wrinkles Aimed at the Manufacturing of Large Wind Turbine Blades
Polymer Composites, EarlyView.The step‐wise progression of the development of cure‐induced wrinkles. Before curing, at room temperature the laminate is resting at the mould face. In the next step, the wrinkle is developing due to thermal gradients. At the end of curing, the composite has cooled down and the undulation is left in, byt the increase in resin stiffness across the ...
