Why the traditional method does not work

1. The time to complete one design loop is very long.

2. Many people involved from different fields: aerodynamics, CAD, structural, control, loads.

No global insight.

3. Interactions between aerodynamics, dynamics, control and loads not fully considered.

Wind turbines (and blades) are growing fast

Blades in AWP: 37.5 m (2006) 61.2 (2012) 77 m (2019)

The design of NEW wind turbines require NEW tools!!!!

Conclusions

Improve Blade Design Process: reduce time-to-market and achieve design targets.

The duration of the design process has been reduced significantly.

Evolve traditional sequential design process to multi-disciplinary holistic approach.

Decisions now based on results rather than on experience or intuition.

Complex interactions are taken into account.

Develop MATLAB-based Application to calculate performance and loads of the WT.

Tool succesfully implemented.

Methods and tools implemented succesfully in already serial production blades.
