2 Aerodynamics and aero elastics
The overall objective of WP2 is to develop an aerodynamic and aero elastic design basis for large multi MW turbines as well as to facilitate the development and the design of multi MW turbines, including possible new and innovative concepts.
Specific objectives are:
• The development of nonlinear structural dynamic models
• Advanced aerodynamic models covering full 3D CFD rotor models, free wake models and improved BEM type models. (The wake description is a prerequisite for the wake modelling in WP8);
• Models for aerodynamic control features and devices. (This represents the theoretical background for the smart rotor blades development in WP 1B3);
• Models for analysis of aero elastic stability and total damping including hydro elastic interaction;
• Development of models for computation of aerodynamic noise.
The main tasks for the first 18 months of the project are the following:
• to quantify the importance of non-linear structural
effects on loads and stability;
• to improve modelling and include effects of shear-coupling and large deformation into beam models and finite elements;
• to verify and develop engineering aerodynamic models by application of full 3D unsteady CFD models in complex inflow such as strong wind shear;
• to overview the requirements of aerodynamic and aero elastic design tools in order to analyse the potential of different advanced control features and aerodynamic devices;
• to develop concepts to improve the link between CFD and aero acoustics predictions.
Final outcome of this work package will be a design-basis consisting of tools and methods for aerodynamic and aero elastic design of future large multi-MW turbines covering possible new and innovative concepts.
