Sequence K used an upwind,\nrigid turbine with a 0\u00b0 cone angle. The wind speeds ranged from 6 m/s to 20 m/s, and data were\ncollected at yaw angles of 0\u00b0 and 30\u00b0. The rotor rotated at 72 RPM. 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\nThe blade pitch angle ramped continuously at 0.18\u00b0/s over a wide range of increasing and\ndecreasing pitch angles. A step sequence was also performed. The blade pitch was stepped 5\u00b0, the\nflow was allowed to stabilize, and the pitch angle was held for 8 seconds. Then the pitch angle step was repeated. Again, a wide range of pitch angles was obtained, both increasing and\ndecreasing. The file lengths for this sequence varied from 96 seconds to 6 minutes, depending on\nthe pitch angle range. Some short points were collected at 0\u00b0 yaw and 3\u00b0 pitch to verify the\nfunctionality of the instrumentation. The file name convention used the initial letter K, followed\nby two digits specifying wind speed, followed by two digits for yaw angle, followed by RU, RD,\nor ST, followed by the repetition digit. The angle-of-attack motion was differentiated by RU\n(ramp up), RD (ramp down), and ST (step down then step up). This sequence is related to\nsequences L and R.\n\n**Data Details**\n\nFile naming information can be found in the attached Word document \"Sequence K Filename Key\", copied from the Phase VI Test Report.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://a2e.energy.gov/data/uae6/uae6.z10.00", "description": "Main dataset landing page with options to request/download", "format": "00", "mediaType": "application/octet-stream", "title": "uae6/uae6.z10.00"}], "identifier": "https://data.openei.org/submissions/4206", "issued": "2018-11-28T00:00:00Z", "keyword": ["00", "Raw Data", "Sequence K", "UAE6", "Unsteady Aerodynamics Experiment Phase VI NREL-NASA Ames Wind Tunnel Experiment", "Wind Tunnel Tests Data", "a2e", "atmosphere to electrons", "eere", "uae6", "weto", "wind", "z10"], "landingPage": "https://a2e.energy.gov/data/uae6/uae6.z10.00", "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 K - Raw Data"}
