Article
Full-text available
Wind tunnel testing of large deformable soft kites for wind energy conversion is expensive and in many cases practically not feasible. Computational simulation of the coupled fluid–structure interaction problem is scientifically challenging and of limited practical use for aerodynamic characterization. In this paper we present a novel experimental...

Article
Full-text available
Airborne wind energy is an evolving renewable energy technology with the potential to reduce material as well as energy investments and to harvest wind resources that have so far not been accessible. Ground generation systems use the pulling force of a kite to generate a linear traction motion driving a drum connected to a generator. To understand...

Project
AWESCO was an interdisciplinary doctoral training network about an innovative renewable energy technology, combining eight academic and three industrial network partners with five associated partners, all selected on the basis of excellence and complementarity. The project has been awarded as a Marie Skłodowska Curie European Training Network within the EU framework programme Horizon 2020 (H2020-ITN-642682).
Project
During the last decade clean and safe Airborne Wind Energy (AWE) systems based on power kites have been discussed by several European research groups. Unlike conventional wind turbines, which operate within the atmospheric boundary layer, AWE systems work at high altitude where the wind in very intense and presents low intermittency. Since ideal generated power increases with the cubic of the wind velocity, AWE systems are considered a disruptive technology because they can increase severely the generated power while reducing the manufacturing costs and the visual impact. GreenKite project is focussed on one of the most important challenges of kite systems: the dynamic and control of a kite under the constraints imposed by the main tether and the bridle lines. It is a multidisciplinary project that involves the development of an efficient and reliable kite flight simulator and data acquisition from real flight of a kite with onboard instruments.
