UAE6 - Wind Tunnel Tests Data - UAE6 - Sequence O - Raw Data
**Overview**
Sequence O: Sin AOA, Parked (P)
This sequence was designed to quantify the blade 3-D unsteady aerodynamic response in the
absence of rotational influences by varying blade pitch angle. This test sequence used an upwind,
rigid turbine with a 0° cone angle. The wind speed ranged from 18.9 m/s to 39.3 m/s, and the yaw
angle was 0° throughout the sequence. The rotor was parked with the instrumented blade fixed at
0° azimuth, and the rotor lock was installed (see Appendix A). 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.
Sinusoidal angle-of-attack histories were designed to emulate 2-D S809 dynamic data obtained at
the OSU wind tunnel (Reuss Ramsey et al. 1995) as well as 1P yawed flow angle-of-attack
variations the turbine could be expected to encounter in routine operation. The reduced frequency
(K), mean angle of attack (?m), and oscillation amplitude (??) were computed for each of the five
primary span locations. The file lengths varied according to the time required to complete 40
oscillations at the specified frequency. The file name convention used the sequence designation
O, followed by two digits for the span location (30, 47, 80, or 95), followed by two digits
representing the condition specified in the test matrix, followed by the repetition digit. Due to
time constraints, the test conditions corresponding to the 63% span location were eliminated. Test points with a static pitch angle of 3° were collected
throughout the sequence to ascertain instrumentation fidelity.
