Stiffening of Wind Turbine Blades – Mitigating leading edge damages
To develop and demonstrate cost effective solutions for mitigating leading edge damages on blades on both existing and future wind turbines, based on Bladena’s patented technologies for mitigating shear distortion. The solutions will be demonstrated on a turbine in operation, full-scale test, sub-structure test and in a pilot project.
The objective of this project is to develop three commercial solutions (Retrofit, New Design Stiffener and Retrofit Damper) and the project plan has been organized in “3 swim lanes”, one for each solution. The process has been designed as shown below for each swim lane: A: Understanding, B: Hypothesis, C: Verification, D: Product development and E: Demonstration. All swim lanes and work packages will be tied together by a series of facilitated work-outs with continuously updated visualization of all findings, issues and conclusions. The project has been structured with 13 work packages: WP0) Project management WP1) Development of a new Standardization process WP2) Damage assessment and measurement techniques WP3) Field Measurement and Testing WP4) Full-scale fatigue testing WP5) Sub-component and sub-structure fatigue testing WP6) Finite Element Simulation WP7) Design Tools for Wind Turbine Blades WP8) Detailed blade modeling implemented in aero-elastic analysis WP9) Product development WP10) Market Entrance Barriers WP11) Visualization and Logging WP12) Design of a new blade
