UAE6 - Wind Tunnel Tests Data - UAE6 - Sequence I - Raw Data

**Overview**

Sequences H, I, and J: Upwind Baseline (F), Upwind Low Pitch (F), Upwind
High Pitch (F)

This test sequence used an upwind, rigid turbine with a 0° cone angle. The wind speed ranged
from 5 m/s to 25 m/s. Yaw angles of ?30° to 180° were achieved at low wind speeds, and angles
of ±10° were achieved for high wind speeds. The blade tip pitch was 3° for sequence H, 0° for
sequence I, and 6° for sequence J. These three sequences were interleaved during testing because
the pitch angle change was easily made by the turbine operator. The rotor rotated at 72 RPM.
Blade and probe pressure measurements were collected. The teeter dampers were replaced with
rigid links, and these two channels were flagged as not applicable by setting the measured values
in the data file to ?99999.99 Nm. The teeter link load cell was pre-tensioned to 40,000 N.

In addition to the standard 30-second campaigns, yaw sweeps were done at 7 m/s and 10 m/s.
These 6-minute campaigns were collected while the yaw drive rotated the turbine 360° at a rate of
1°/s. The file names for these campaigns use the letter designation, followed by two digits for
wind speed, followed by YS, followed by 000.
