Abstract

This paper describes work carried out as part of the Horizon 2020 POWDERBLADE project aimed at developing large (60m+) commercial wind turbine blades. The aims of the project were to reduce blade cost and weight without compromising reliability and performance, by introducing a carbon/glass fibre hybrid composite spar and leveraging novel powder epoxy resin technology. A 6.0m torsion box demonstrator was designed by Suzlon Energy, manufactured by EireComposites, and tested by the University of Edinburgh. The tests followed the DNVGL-ST-0376 [12] blade test specification and applied four critical load cases identified during its design. The test cases were performed in ascending load order, after which the lowest load case was repeated. The torsion box demonstrated no reduction in stiffness or natural frequency throughout the test. This work gives a detailed description of the test program carried out to validate the torsion box design.
