Tower clearance

The information about the tower clearance of the blade tips is a revealing indicator of the evaluation of the sheet behavior in different load conditions. In addition to the aerodynamic influences also the rigidities of the individual blades are displayed in these measurements.


Usually, in this measurement, the behavior of the system is displayed on several days with different wind situations.

Graph shows the tower clearance of 3 blades over 100 rotations.

Measurement results will be provided as an excel sheet.
