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

**Overview**

Sequence M: Transition Fixed (P)

Test sequence M used an upwind, rigid turbine with a 0° cone angle. The wind speed ranged from
5 m/s to 15 m/s. Yaw angles ranged from 0° to 90°. The blade tip pitch was 3°. The rotor rotated
at 72 RPM. Blade pressure measurements were collected. The five-hole probes were removed and
the plugs were installed. Plastic tape 0.03-mm-thick was used to smooth the interface between the
plugs and the blade. 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. During post-processing, the probe
channels were set to read ?99999.99. Zigzag tape was installed near the leading edge of the
instrumented blade on both the upper and lower surfaces as described in Appendix K.
In addition to the standard 30-second campaigns, yaw sweeps were done at 7 m/s and 10 m/s.
These 90-second campaigns were collected while the yaw drive rotated the turbine 90° 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 YSU, followed by 00.
