## Short summary
The dataset includes time series of wind data from 4 masts, located at ECN, Petten, The Netherlands. The period includes 49 hours of turbulence measurements from an array of masts., which starts in 2002. Furthermore, some 4 Hz time series from the 3D Sonic have been included.

## Project description
Power performance measurements on the LW 5/2.5. These measurements are never carried out due to problems with the turbine. The winddata that were available are included in the international winddatabase.
The primary goal was to design and build and test a flexible rotor (two blades, diameter 21.6 m) with passive tip-pitch control and a teetered hub with an elastomeric bearing. The FLEXTEETER rotor was tested at the 25m HAWT test facility of ECN. During the project the wind input was measured with a set of four meteo masts. The wind data obtained as part of the test of FLEXTEETER are available for the "Database on Wind Characteristics".
## Measurement system
The measurements setup consists of a mixture of cups, vanes and a sonic anemometer.
The measurement system consists of 4 meteorological mast, mast no. 1, 2, 3 were placed West of the turbine and mast 4 at the East side. The measurements system was based on a PDP datalogger and the data were transferred to a DIGITAL VAX system (VAX VMS operating system with data handling routines and programs developed at ECN). The data to be measured were divided in two groups: group 1, wind data with a recording frequency of 4 Hz; group 2, turbine operational data and mechanical load data with a recording frequency of 32 Hz. The maximum duration of a consecutive measurement with 32 channels in both groups was about 18 hrs.
