CHAPTER 13 Blade materials, testing methods and structural design Bent F. S rensen , John W. Holmes , Povl Br ndsted & Kim Branner Ris National Laboratory for Sustainable Energy The Technical University of Denmark. A major trend in wind energy is the development of larger wind turbines for offshore wind farms. Since access to offshore wind turbines is diffi cult and costly, it is of great importance that they operate safely and reliable. The wind turbine rotor blades, which are the largest rotating component of a wind turbine, are designed for an expected lifetime of 20 years.
knowledge of the performance, the strength and the endurance of the full structure and of the basic materials used. The goal of the design process is to ensure that ... Steel bolts are present at the root, where the blade is to be attached to the hub of a wind turbine.
