WP1: Understanding the leading edge erosion
|
Understanding the mechanisms of degradation of leading edges. |
- Testing the various coatings using the Rain erosion tester and Single Point Impact Fatigue tester. X-ray tomography of surface/inside volume of blades.
|
|
WP2: Multiscale computational modelling and numerical simulation of leading edge erosion
|
Providing computational tools for numerical testing and optimization of LE protective solution. |
- Computational (finite element) micromechanical modelling of degradation protective systems of wind turbine blades.
- Coating cracking, cone cracks interfacial debonding of the protective coating, cracks in composite and spalling of the coating parts will be reproduced in simulations.
|
| WP3: Optimized protective solutions with graded engineered coatings |
Developing optimized, impact absorbing, damage arresting coating system for extra-durable blade protection. |
- Development of new tailor-made coatings raw materials, development of enhanced binders, reinforced particles and their controlled distribution, additional protective layers.
- The protective systems will counteract the damage mechanisms, by toughening the material and arresting microcracks (particle reinforcement), increasing damping properties of polymers, additional stiff and soft layers of various thicknesses, ensuring the wave absorption/dispersion

WP4: Validation for field applications, testing and exploitation
|
Validation of the developed modeling tools, guidelines and new materials solutions for industrial application and exploitation.
|
- The main results are validated in laboratories of industrial partners and on real wind turbines.
