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.

Wind turbine blade fixing mechanism

2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017
In this paper the blade fitting mechanism is developed. In this mechanism various types of blades can be fitted. The pitch angle of the blade can also be varied. Cylinders are welded to the hub. Another cylinder with small diameters is welded to a metallic square strip is welded to the blade with one square plate.

Variable length blades wind turbine

IEEE Power Engineering Society General Meeting, 2005, 2005
Energy Unlimited Inc has developed variable length wind turbine blades. These blades are fitted with a tip that automatically extend outwards in response to light winds and retract in stronger winds. This action allows higher energy capture in low wind conditions, while minimizing mechanical loads in high wind conditions.

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

CFD analysis of the angle of attack for a vertical axis wind turbine blade

Energy Conversion and Management, 2019
The Angle of Attack (AOA) of the Vertical Axis Wind Turbines (VAWTs) blades has a dominant role in the generation of the aerodynamic forces and the power generation of the turbine. However, there is a significant uncertainty in determining the blade AOAs

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
