This test sequence used an upwind,\nrigid turbine with a 0\u00b0 cone angle. The wind speed ranged from 18.9 m/s to 39.3 m/s, and the yaw\nangle was 0\u00b0 throughout the sequence. The rotor was parked with the instrumented blade fixed at\n0\u00b0 azimuth, and the rotor lock was installed (see Appendix A). Blade and probe pressure\nmeasurements were collected. The teeter dampers were replaced with rigid links, and these two\nchannels were flagged as not applicable by setting the measured values in the data file to\n-99999.99 Nm. The teeter link load cell was pre-tensioned to 40,000 N.\n\nSinusoidal angle-of-attack histories were designed to emulate 2-D S809 dynamic data obtained at\nthe OSU wind tunnel (Reuss Ramsey et al. 1995) as well as 1P yawed flow angle-of-attack\nvariations the turbine could be expected to encounter in routine operation. The reduced frequency\n(K), mean angle of attack (\u03b1m), and oscillation amplitude (\u03b1\u03c9) were computed for each of the five\nprimary span locations. The file lengths varied according to the time required to complete 40\noscillations at the specified frequency. The file name convention used the sequence designation\nO, followed by two digits for the span location (30, 47, 80, or 95), followed by two digits\nrepresenting the condition specified in the test matrix, followed by the repetition digit. Due to\ntime constraints, the test conditions corresponding to the 63% span location were eliminated. Test points with a static pitch angle of 3\u00b0 were collected\nthroughout the sequence to ascertain instrumentation fidelity.\n\n**Data Details**\n\nFile naming information can be found in the attached Word document \"Sequence O Filename Key\", copied from the Phase VI Test Report.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://a2e.energy.gov/data/uae6/uae6.z14.00", "description": "Main dataset landing page with options to request/download", "format": "00", "mediaType": "application/octet-stream", "title": "uae6/uae6.z14.00"}], "identifier": "https://data.openei.org/submissions/4210", "issued": "2018-11-29T00:00:00Z", "keyword": ["a2e", "atmosphere to electrons", "wind", "weto", "eere", "uae6", "Unsteady Aerodynamics Experiment Phase VI NREL-NASA Ames Wind Tunnel Experiment", "UAE6", "Wind Tunnel Tests Data", "Sequence O", "Raw Data", "z14", "00"], "landingPage": "https://a2e.energy.gov/data/uae6/uae6.z14.00", "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2020-03-27T00:00:00Z", "programCode": ["019:010"], "projectNumber": "67025", "projectTitle": "Wind Data Hub", "publisher": {"@type": "org:Organization", "name": "Wind Energy Technologies Office (WETO)"}, "title": "UAE6 - Wind Tunnel Tests Data - UAE6 - Sequence O - Raw Data"}
