Innovative design procedures for large-scale wind turbine blades
نویسنده
چکیده
cost-effective, lightweight, large-scale wind turbine blades. Material costs are continuously changing, and the use of glass fibres (E-, Sand R-glass) and carbon fibre should be explored considering density/cost, specific stiffness and strength. The various fibre angles should also be used to best meet the design requirements. Rather than just a straight blade, various blade geometries should be investigated to increase power efficiency and to alleviate aerodynamic loads and increase fatigue life. Pre-bending will certainly alleviate the use of expensive high-stiffness materials.

متن کاملWind Turbine Blade Design for Subscale Testing
Two different inverse design approaches are proposed for developing wind turbine blades for sub-scale wake testing. In the first approach, dimensionless circulation is matched for full scale and sub-scale wind turbine blades for equal shed vorticity in the wake. In the second approach, the normalized normal and tangential force distributions are matched for large scale and small scale wind turb...
