UAE6 - Wind Tunnel Tests Data - UAE6 - Sequence R - Raw Data
**Overview**
Sequence R: Step AOA, No Probes (P)
This sequence was designed to quantify the effect of the five-hole probes on the 3-D blade static
angle-of-attack response in the presence of rotational influences by repeating Sequence K without
five-hole probes. This test sequence used an upwind, rigid turbine with a 0° cone angle. The wind
speeds ranged from 6 m/s to 20 m/s, and data were collected at yaw angles of 0° and 30°. 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.
The blade pitch angle ramped continuously at 0.18°/s over a wide range of increasing and
decreasing pitch angles. A step sequence was also performed. The blade pitch was stepped 5°; the
flow was allowed to stabilize; and the pitch angle was held for 5 seconds. Then the pitch angle
step was repeated. Again, a wide range of pitch angles was obtained, both increasing and
decreasing. The file lengths for this sequence varied from 96 seconds to 6 minutes, depending on
the pitch angle range. Some short points were collected at 0° yaw and 3° pitch to ascertain the
functionality of the instrumentation and repeatability over time. The file name convention used
the initial letter R, followed by two digits specifying wind speed, followed by two digits for yaw
angle, followed by RU, RD, or ST, followed by the repetition digit. The angle of attack motion
was differentiated by RU (ramp up), RD (ramp down), and ST (step down, then step up). This
sequence is related to Sequences K and L.
