This report is the second report covering the research and
demonstration project “Eksperimentel vingeforskning:
Strukturelle mekanismer i nutidens og fremtidens store vinger
under kombineret last”, supported by the EUDP program. A
34m wind turbine blade from SSP-Technology A/S has been
tested in edgewise direction (LTT). The blade has been
submitted to thorough examination by means of strain gauges,
displacement transducers and a 3D optical measuring system.
This data report presents results obtained during full scale
testing of the blade up to 80% Risø load, where 80% Risø load
corresponds to 100% certification load. These pulls at 80%
Risø load were repeated and the results from these pulls were
The blade was reinforced according to a Risø DTU invention,
where the trailing edge panels are coupled. The coupling is
implemented to prevent the out of plane deformations and to
reduce peeling stresses in the adhesive joints. Test results from
measurements with the reinforcement have been compared to
results without the coupling.
The report presents only the relevant results for the 80% Risø
load and the results applicable for the investigation of the
influence of the invention on the profile deformation.
