Automatic Design and Optimization of Wind Turbine Blades
2006 International Conference on Computational Inteligence for Modelling Control and Automation and International Conference on Intelligent Agents Web Technologies and International Commerce (CIMCA'06), 2006This paper is concerned with the description of an automatic design environment developed for the generation of optimal windmill blade profiles as well as the presentation of some results of its application. The objective is to provide a tool for the definition of wind turbine blades that are adapted to specific locations characterized by particular ...

Reliability-based design of wind turbine blades
Structural Safety, 2011Reliability-based design of wind turbine blades requires identification of the important failure modes/limit states along with stochastic models for the uncertainties and methods for estimating the reliability. In the present paper it is described how reliability-based design can be applied to wind turbine blades.

Optimization of flatback airfoils for wind turbine blades
Aircraft Engineering and Aerospace Technology, 2010PurposeIn recent years, the airfoil sections with blunt trailing edge (called flatback airfoils) have been proposed for the inboard regions of large wind‐turbine blades because they provide several structural and aerodynamic performance advantages. The purpose of this paper is to optimize the shape of these airfoils for optimal performance using a ...

Automated cleaning of wind turbine blades with no downtime
2017 IEEE International Conference on Industrial Technology (ICIT), 2017Several factors affect the power generation efficiency of wind energy extracted from wind turbines. One of them is dust accumulation resulting in roughness of the blade surface and resulting in power loss. To overcome this problem, wind turbine blades need to be cleaned frequently.

A Status of Study on Icing of Wind Turbine Blades
2011 Second International Conference on Digital Manufacturing & Automation, 2011During recent years, more and more wind turbines are planned and erected in cold and hostile cLimate sites, there may be more higher icing probabiLity during the year. The problem of icing accretion on wind turbine blades brings many adverse effects.

An Anthropomorphic Wind Turbine Blade
Journal of Energy Resources Technology, 2019This study presents a new wind turbine blade design for overcoming the restrictions of large-scale wind turbines deployment. The road design, terrain nature, and logistic capabilities represent the main barriers to maneuver blades during a journey to a windy site.

Modal Response of 3-Bladed Wind Turbines
ASME 2002 Wind Energy Symposium, 2002A set of linear equations describing the motion of an operating 3-bladed HAWT are obtained from the dynamic characteristics of the stationary turbine by adding rotating frame effects. The approach makes use of the Coleman multi-blade transformation to present all results relative to the fixed frame.

Acoustic Techniques for Wind Turbine Blade Monitoring
Key Engineering Materials, 2007The total electrical generation capacity from wind sources in the International Energy Agency (IEA) Wind Member Countries has increased from 4 GW in 1995 to more than 51 GW in 2005 thus underlining the strategic importance of the resource. In the last year alone the UK increased its wind generation by 447 MW, an increase of 85% over that for the ...

An Evolutionary Environment for Wind Turbine Blade Design
2005The aerodynamic design of wind turbine blades is carried out by means of evolutionary techniques within an automatic design environment based on evolution. A simple, fast, and robust aerodynamic simulator is embedded in the design environment to predict the performance of any turbine produced as intermediate individual of the evolutionary process.
