Aerodynamic Wind-Turbine Blade Design for the National Rotor Testbed
News Article, November 13, 2015 • The NRT blade shape as viewed from the tip and at an elevation angle of 30° above the suction surface. Sandia has designed a new wind-turbine blade for the National Rotor Testbed (NRT) project and for future experiments at the Scaled Wind Farm Technology (SWiFT) facility with a specific focus...

First Wake Data Captured During Wake Steering Experiment at the SWiFT Facility
News Article, July 14, 2016 • Researchers at Sandia National Laboratories and the National Renewable Energy Laboratory (NREL) have met a major project milestone as part of the Department of Energy Atmosphere to Electrons (A2e) Wake Steering Experiment being conducted at the Scaled Wind Farm Technology (SWiFT) Facility. The team successfully installed the Technical University of...

National Rotor Testbed Rotor Design Integrated Airfoil Performance Results
News Article, February 24, 2015 • The National Rotor Testbed (NRT) team is examining the effect of airfoil choice on the final design of the new rotor for the Scaled Wind Farm Technology (SWiFT) facility. The airfoil family would ideally be designed to operate in the relevant SWiFT-scale Reynold’s number range, 1–2 million, and be experimentally...

New tool brings some West Texas wind to the Duke City — virtually
News Article, February 2, 2021 • Sandia researchers have a new tool that allows them to study wind power, to see whether it can be efficiently used to provide power to people living in remote and rural places or even off the grid, through distributed energy. A new, custom-built wind turbine emulator has been installed at...
A researcher examines Sandia’s new wind turbine motor, which will allow the distributed energy team to study how real wind farms will behave under a variety of conditions and in different locations.

Sandia Wake-Imaging System Successfully Deployed at Scaled Wind Farm Technology Facility
News Article, September 18, 2015 • The Sandia Wake-Imaging System (SWIS) was deployed for a full-scale field demonstration at the Sandia Scaled Wind Farm Technology (SWiFT) facility in Lubbock, Texas, in July. This successful field demonstration was a culmination of over 3 years of technical development; more than a year of safety, environmental, and regulatory approvals;...

SWiFT Facility Prepared for More-Efficient Operations & Advanced Turbine-Turbine Wake-Interaction-Control Research
News Article, October 16, 2015 • The SWiFT facility comprises three heavily instrumented and modified variable-speed, variable-pitch Vestas V27 turbines and two 60 m anemometer towers, with the first two turbines spaced three diameters apart, perpendicular to the prevailing oncoming wind, and the third turbine five diameters downwind (the turbines form a three, five-, six-rotor-diameter-length triangle)....
