Camera / Raw Data

**Overview** The SUMR-D CART2 turbine data are recorded by the CART2 wind turbine's supervisory control and data acquisition (SCADA) system for the Advanced Research Projects Agency–Energy (ARPA-E) SUMR-D project located at the National Renewable Energy Laboratory (NREL) Flatirons Campus. For the project, the CART2 wind turbine was outfitted with a highly flexible rotor specifically designed and constructed for the project. More details about the project can be found here: https://sumrwind.com/. The data contain video data of the wind turbine blades during operation as well as while parked. Since the blades had a coning angle, the blades are only in frame of the video camera when the blades are in a pitched to run configuration. **Data Details** For photogrammetry calibration of the video data, the following can be used: Blade 1, 8 meter outboard target: 1.43 mm/pixel; Blade 1, 13 meter outboard target: 2.23 mm/pixel; Blade 1, tip: 3.17 mm/pixel; Blade 2, 8 meter outboard target: 1.6 mm/pixel; Blade 2, 13 meter outboard target: 2.67 mm/pixel; Blade 2, tip: 3.72 mm/pixel. This calibration provides the span. For the offset, the attachment explains how to obtain an offset calibration when the blade is offloaded.
