This test sequence used an\nupwind, rigid turbine with a 0\u00b0 cone angle. Wind speeds of 20 m/s and 30 m/s were used, and all\ndata were collected at a yaw angle of 0\u00b0. The rotor was parked with the instrumented blade fixed\nat 0\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\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\nstep was repeated. Again, a wide range of pitch angles was obtained, both increasing and\ndecreasing. The file lengths for this sequence varied from 5 to 10 minutes, depending on the pitch\nangle range. The file name convention used the initial letter L followed by two digits specifying\nwind speed, followed by 00 for yaw angle, followed by RU, RD, or ST, followed by the repetition\ndigit. The angle-of-attack motion was differentiated by RU (ramp up), RD (ramp down), and ST\n(step down, then step up). This sequence is related to sequences K and R.\n\n**Data Details**\n\nFile naming information can be found in the attached Word document \"Sequence L Filename Key\", copied from the Phase VI Test Report.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://a2e.energy.gov/data/uae6/uae6.z11.00", "description": "Main dataset landing page with options to request/download", "format": "00", "mediaType": "application/octet-stream", "title": "uae6/uae6.z11.00"}], "identifier": "https://data.openei.org/submissions/4207", "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 L", "Raw Data", "z11", "00"], "landingPage": "https://a2e.energy.gov/data/uae6/uae6.z11.00", "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 L - Raw Data"}
