Application of Circulation Controlled Blades for Vertical Axis Wind Turbines [PDF]

open access: yes, 2013
The blades of a vertical axis wind turbine (VAWT) rotor see an inconsistent angle of attack through its rotation. Consequently, VAWT blades generally use symmetrical aerofoils with a lower lift-to-drag ratio than cambered aerofoils tailored to maximise ...

Design, construction and testing of a simple blade pitch measurement system for small wind turbines

open access: yes, 2007
Reliability in performance is a key factor in ensuring the sustainable operation of a small wind turbine. Despite the great potential of small wind turbines to provide electric power, particularly in remote areas, many small wind turbines have short ...

Research on the Power Output of Different Floating Wind Farms Considering the Wake Effect

open access: yesJournal of Marine Science and Engineering
For floating wind turbines, one of the most interesting and challenging issues is that the movement of the rotor is strongly related to its floating platform, which results in corresponding variations in the wake characteristics of the turbine.

Predicting The Resale Asking Price Of Wind Turbines Using A ML Model Trained On Data From An Online Resale Platform

open access: yesProceedings of the Conference on Production Systems and Logistics
Around half of the currently 30,000 active wind turbines in Germany will reach the end of their service life by 2030, which is generally defined by the manufacturer as 20 years of operation.

How the factoid of wind turbines causing ‘vibroacoustic disease’ came to be ‘irrefutably demonstrated’

open access: yesAustralian and New Zealand Journal of Public Health, 2013
Objective : In recent years, claims have proliferated in cyberspace that wind turbines cause a large variety of symptoms and diseases. One of these, “vibroacoustic disease” (VAD) is frequently mentioned. The aim of this study is to examine the quality of

Design and construction of a simple blade pitch measurement system for small wind turbines

open access: yes, 2009
For small wind turbines to be reliable they must have in place good mechanisms to protect themselves against very high winds or sudden removal of load. One common protection method in small wind turbines is that of blade feathering.
