Calibration of the Anemometer in the Wind Tunnel
Have a look in the wind tunnel of the Yacht Research Unit Kiel (YRU-Kiel) where the anemometer is been calibrated...
To optimize the measurement results of the anemometer of the PerforManD system, the sensor is calibrated with a Laser-Doppler-Anemometer (LDA). The LDA is a high-tech anemometer which allows measuring the wind speed contactless. This means that the LDA is not influencing the flow. It is the perfect instrument for such calibration.
The calibration been done for all possible true-wind, pitch and heel angles and improves the measurement results significantly.
