This report is part of the research project entitled
“Eksperimentel vingeforskning: Strukturelle mekanismer i
nutidens og fremtidens store vinger under kombineret last”
where a 34m wind turbine blade from SSP-Technology A/S
was tested in combined flap and edgewise load. The applied
load is 55% of an imaginary extreme event based on the
certification load of the blade.
This report describes the reason for choosing the loads and the
load direction and the method of applying the loads to the
blade. A novel load introduction allows the blade to deform in a
more realistic manner, allowing the observation of e.g.
transverse shear distortion.
The global and local deformation of the blade as well as the
blades’ respond to repeated tests has been studied and the result
from these investigations are presented, including the
