They can also cause the blade’s shape to change noticeably: at specific sections or areas the whole blade and/or the surface of the blade sometimes deflect, even changing cross-section shape. An example of such changes is the very obvious deflection of the blade tip that can be observed on many operating wind turbines. In fact, maximum blade tip deflection is an important design parameter as the blade must be kept at a safe distance from the tower. Another problem with large blade deflection may arise as blade elements are translated out of the rotor plane or in lead-lag direction.
E. single loading and unloading event from a start level to another load level back to the start level) is very small, and it is only because of the large number of these load cycles that considerable damage can be accumulated in the blade’s material. It is important to understand that both types of loading always occur at the same time and without pause throughout the turbine’s service life. It is up to the designer and her/his understanding of the particular load case to indicate which load components are to be analysed and which type of analysis, ultimate or fatigue, is appropriate.
