Chalmers University

Chalmers University of Technology have initially focused on investigating the blades for the Ampair turbine; several free-free vibration tests as well as destructive testing of blades have been performed. A master student, Mladen Gibanica, is currently working on using substructuring techniques to couple analytical and experimental models of the blades to the hub. Calibrated FE models of the blades have also been developed.
