High resolution wind speed measurements with multicopters of the SWUF-3D UAS fleet - calibration and verification in a wind tunnel with active grid

This dataset contains aggregated measurements from multicopter UAS. The data were measured during the period from October 5, 2022 to October 12, 2022 in the ForWind wind tunnel at the University of Oldenburg with UAS of the SWUF-3D fleet against Constant Temperature Anemometer (CTA). 

Recorded data are provided for measurement flights in different generated wind profiles, i.e. staircase profiles, gusts, velocity steps and statistical turbulence. The measurement data consist of the accelerations measured by the UAS in its longitudinal and lateral axes, as well as the wind speeds measured by the CTA. The latter data were sampled down to the sampling rate of the UAS wind measurement. For the measurements in statistical turbulence, additional files are provided which contain the wind speeds measured by the CTA in its original sampling rate. Each file contains the data for a single measurement flight, as well as information in the header about the ambient conditions in the wind tunnel. The file names contain the following metadata:

for "gust" files:

• V0 :                     inertial velocity [m/s]
• V_g :                   gust velocity amplitude [m/s]

for "staircase" files:

• uas :                the ID of the UAS used [-]
• heading :       yaw angle of UAS in relation to longitudinal axes of wind tunnel

for "turbulence" files:

• V0 :                fan wind speed [m/s]
• I :                    turbulence intensity [%]
• f_cta :             sampling frequency of reference sensor [Hz] (for files with original sampling rate)

for "velocity step" files:

• V0 :                 lower wind speed
• V_du :            wind speed aimed for of upward and downward velocity step

All filenames end with the test date in YYYY-MM-DD format.
