MAS 2009 | Fidu Rotor- Coeus at DMY Berlin Exhibition


The MAS class of 2008/2009 exhibited their FiDU Rotors at the DMY Berlin Exhibition. The prototypes generated a tremendous level of interest and received much acclaim. In the coming weeks, the rotors will be tested in ETH's wind tunnels. A brief description of the project is attached below.

Die Idee einer Windturbine entwickelte sich aus dem Bestreben nach neuen Applikationen der FIDU-Technologie zu forschen, wobei die “spezifische“ Formen gleich zu funktionalen Nutzer gemacht wurde. Massgebend war das System eines Vertikalläufers (Vertical Axis Windturbine- VAWT). Diese Turbinen sind windrichtungsunabhängig, freier in der Formgestaltung und verfügen somit über ein grösseres Anwendungsgebiet als die Horizontalläufer (HAWT).

Ausgangslage für die Dimensionierung und die Proportionen waren existierende Studien zu freistehenden Windturbinen. In Modellen wurde getestet welche Formen und Konturen zu den gewünschten Querschnittsprofilen führen. Drei verschiedene Flügeldesigns wurden schliesslich weiterentwickelt- die gebogenen Einkammer- und Dreikammerflügel und der Wellenformflügel. Diese Variationen haben zu unterschiedlichen Lösungen in den Detailanschlüssen an die dreiarmigen Träger geführt. Schon während der Produktion der Hauptelemente zur Erstellung der Windturbine wurde nach einfachen und passenden Montagelösungen gesucht. Die grösste Herausfordung dabei war, die deformierten FiDU Elemente präzise und stabil miteinander zu verbinden

In the search for possibilities concerning renewable energies, a wind turbine is demonstrated which can be produced using FiDU technology. A Vertical Axis Wind Turbine (VAWT) format was chosen since they can operate efficiently without sophisticated and expensive equipment to orient them into the wind. They are often more flexible in their design and have a wider range of applications than horizontal turbines with regards to the potential to decentralize yet upscale the capacity for energy production.

The dimensions and proportions were based on existing studies of free-standing wind turbines. Models were used to test which forms and contours resulted in the desired profiles. Three separate wing designs were subsequently advanced and developed: a single-chamber, triple-chamber and a waveform wing. These designs lead to different approaches regarding the connection of the three-armed support. The production of the primary components of the wind turbine was accompanied by a search for suitable assembly methods. The biggest assembly challenge was combining the deformed FiDU elements in a precise and stable manner.
