This document summarizes the development history of LM Wind Power's wind turbine blades, including their earliest 61.5m blade introduced in 2004 up to their most recent 88.4m blade. It discusses the challenges of developing an 88.4m blade and the technologies and validations needed, including optimized aerodynamics, loads, geometry, and structure as well as material and component testing. The document also covers standardization of processes and materials for industrialization and quality control plans to support manufacturing quality products.

Developed in cooperation with
ADWEN for the AD 8-180

7. 1. We have to have the blade
“optimized”.
2. We have to generate the optimal &
validated design for the turbine as
a whole.
3. We have to have the right material
technology - validated.
4. We have to have the right
solutions for the size of the blade.
5. Technologies need to be ready for
serial production.
What is the challenge to make 88.4?

8. 1. Optimized by matching Aerodynamics,
Loads, Geometry & Structure

9. 2. Technology Material, Coupon and
Component Validation Program

10. 3. LM 88.4 P – Size matters
LM 88.4 P vs. LM 73.5 P
LM 88.4 P vs. LM 73.5 P
LM 88.4 P vs. LM 42.1 P
LM 88.4 P vs. LM 42.1 P
LM 88.4 P vs. LM 61.5 P/P2
LM 88.4 P vs. LM 42.1 P
Where the LM 73.5 P stops, the LM 88.4 P
still has 2m of chord.
