But it does move.

But it does move.

The engineers and composite specialists manufactured and assembled the A6 test system in Lemwerder. The final work focused primarily on controlling the system, i.e. programming the software that controls the pitch motors.
 

In order to be able to carry out the assembly and commissioning of the system efficiently and safely at the future location in Switzerland, the system will be installed on an auxiliary tower around 5 m high. This allows the lower rotor blades to be attached and the control system to be tested at 1/1.
 

At the beginning of October, the time had come: the turbine was set in motion with the help of the generator and the various control processes could be tested.

The challenge of the sealing ring
 

There was a small hurdle to overcome: The cooling system of the pitch motors, which regulates the operating temperature with a water-glycol mixture, was leaking at one point. Although the cooling system would not have been used at the current temperatures, we decided to dismantle the pitch motors again and check the seals. The subsequent leak tests were successful and the system is now ready for summer operation.

Off to Brütten and into the wind
 

The next step was to transport the entire turbine to Brütten. There, the rotor head was also assembled on an auxiliary tower and then mounted on the waiting tubular tower using a crane.
