Since 2020, we have owned and operated our own wind turbine on Taggenberg (Winterthur ZH). To clarify the potential of small wind turbines, we offer power measurements with a real small wind turbine. In addition, the IET has its own vertical-axis wind turbine/wind tunnel with an H-rotor. 

We have purchased a wind turbine at Taggenberg, Winterthur (ZH). It is a light wind turbine AV-7 of the company Aventa AG from Switzerland, with three rotor blades of 6 m length and a nominal power of 6 kW. The turbine was put into operation in December 2002. The average annual wind speed at hub height is about 3.0 m/s, which results in an electricity yield of about 12'000 kWh/a.

We plan to use this turbine for various research projects and for teaching. We are already testing our MEMS pressure measurement system "Aerosense" on the rotor blades. We also offer the facility for external research projects and tests. We look forward to hearing from you!

To clarify the potential of small wind turbines, we offer power measurements with a real wind turbine. The "Windflower" is efficient, quiet and also looks nice. With a diameter of 2 m, it generates up to 1 kW of power, which can be fed directly into the electricity grid.

A power measurement during one year with the Windflower gives you a good idea of how much electricity can be generated with a small wind turbine at your location. You organise the site with the associated clarifications. We take care of the professional wind power measurement for your site.

The open wind tunnel was originally built for optimising wind turbines with a vertical axis of rotation.

While a few designs have become established for horizontal-axis wind turbines, there are still a large number of different designs for vertical-axis ones. This indicates that the optimal shape of such turbines has not yet been found. In addition to the possibility of optimisation by means of numerical simulations, the IET has its own vertical-axis wind turbine with an H-rotor. Different blades can be produced for this turbine using 3D printing. In this way, different blade profiles and angles of attack can be investigated.

In order to be able to test our models and prototypes, a test facility was set up. The basis for this is a wind machine with a diameter of 1.5 m, a maximum volume flow of 100'000 m³/h and a maximum speed of 90 km/h. The wind machine has a maximum speed of 90 km/h and a maximum volume flow of 100'000 m³/h. In order to optimise the measurements with our test facility, it is constantly being improved.
