Agile Wind Power AG reaches milestone: Vertical Sky® turbine successfully installed in Brütten
The Vertical Sky®-A6 test turbine developed in Dübendorf and produced in Germany was successfully installed at the end of October. This milestone marks a significant step towards the series production of the A40, which is set to be launched on the market for the first time at the end of 2026 with a nominal output of 1 MW.
Agile Wind Power AG reaches a milestone: Vertical Sky® turbine successfully installed in Brütten
The schedule for production and installation was tight, as delivery of the first 1 MW turbines is planned for the end of 2026 The test turbine, which at around 23 meters high and 6 meters in diameter is around six times smaller than the final turbines, is used to test the operational management, i.e. the control of the turbine
The various pre-programmed positions of the individual rotor blades were calculated by computer simulation and tested on a 2-metre model in the wind tunnel The aim of the A6 turbine is to test the control system On the one hand with regard to various so-called safety states, and on the other hand to measure forces and vibrations in different wind situations
Assembly work like clockwork
The entire dismantling and assembly of the turbine in the last two weeks of October went without a hitch The entire turbine was manufactured, assembled and tested at the company's own factory in Lemwerder (Germany) It was then dismantled and packed for transportation to Switzerland
The components traveled to Brütten, near Winterthur, in two trucks. A crane loaded the various parts into their designated positions on the construction site. Then the assembly of the turbine began, step by step, just as it had been discussed the week before. As the turbine had already been assembled and tested in the production hall, the individual steps were well known.
Reaching the goal after 4 days
The entire rotor head, consisting of the three rotor arms and the pairs of rotor blades attached to them, was hoisted onto the waiting concrete mast and fixed in place without any major interruptions. Prior to this, the control and power cables were pulled in and the individual cables were connected to the control panels. On the evening of installation, the system could be turned for the first time - still with the help of the generator.
Off to the big test - the next steps
In addition to the actual commissioning, various tests are planned for the following weeks. An initial test to clarify safe operation has already been carried out successfully. Before further tests can be carried out, the system, in particular the wind measurement, must be calibrated. Further tests will examine the various force profiles, torque changes and vibrations.
The handover to automatic operation is planned for February 2025.
The fully assembled A6 test system is ready! Another milestone has been reached. Many thanks to everyone involved for their great work.

The rotor blade halves are attached to the pitch motors. These control the pitch angle of the individual blades in real time during the 360° rotation in order to always ensure the optimum position of the blade in relation to the wind.
