Concepts for adaptive wind turbine blades

2002 ASME Wind Energy Symposium, 2002
Bend-twist coupling in wind turbine blades has been shown to reduce both fatigue and extreme operating loads, especially when applied in conjunction with a pitch-controlled rotor. This type of coupling has been used in other industries, implemented either through biased lay-ups of fiber-reinforced materials, or with swept wings.

Fluidic Load Control for Wind Turbine Blades

47th AIAA Aerospace Sciences Meeting including The New Horizons Forum and Aerospace Exposition, 2009
This paper describes the initial steps into the investigation of the possibility of reducing fatigue loads on wind turbine blades by the application of fluidic jets. This investigation involves static pressure measurements as well as numerical simulations for a non-rotating NACA-0018 airfoil.

Optimisation of wind turbine blades

Journal of Materials Processing Technology, 2005
Abstract The manufacturing cost of WT blade is about 15–20% of wind turbine production cost. The expenses of innovations in design of blades represent the small amount of overall cost of wind turbine production. Profits coming from better structural model, use of suitable composite materials and better techniques of manufacturing, both the blades and

Intelligent blade for wind turbines

20th 2001 ASME Wind Energy Symposium, 2001
Simulation and testing to develop an Intelligent Blade for wind turbines is presented in this paper. The concept blade has an integrated sensor system for structural health monitoring that will continuously monitor the condition of the blade, warn of initiating damage, and provide instant information that can be used to regulate loading in the blade to

A flexible turbine blade for passive blade pitch control in wind turbines

2011 IEEE Power Engineering and Automation Conference, 2011
We present a flexible wind turbine blade that effectively pitches itself according to variable wind loading. In contrast to rigid turbine blades, where active controls are often required to pitch blades, the flexible or morphing blade adjusts its geometry passively, eliminating the need for costly electromechanical systems. We analyze the airfoil using

Recycling wind turbine blades

Renewable Energy Focus, 2009
WITH A BOOMING WIND ENERGY INDUSTRY, DRIVING THE DEVELOPMENT OF LARGER AND LARGER TURBINES, THE QUESTION IS NOW ARISING OF HOW TO DEAL WITH WIND TURBINES AT THE END OF THEIR LIFECYCLE, AND PARTICULARLY THOSE WIND TURBINE BLADES MADE OF HARD-TO-RECYCLE COMPOSITES.
