It served as a test bed for development of many concepts for use in larger units. This design had a 38-metre diameter downwind two-bladed rotor, coupled to a synchronous generator, with a power rating of 100 kW at 8 m/s wind speed. A speed increaser stepped up the 40 r/min of the turbine to drive an 1800 r/min generator.
It was the first of many now-famous NACA and NASA wind tunnels. Although this specific wind tunnel was not unique or advanced, it enabled NACA engineers and scientists to develop and test new and advanced concepts in aerodynamics and to improve future wind tunnel design.

On June 26, 2018, the US Air Force informed NASA it had assigned the X-59 QueSST designation to the demonstrator. [7] By October, NASA Langley had completed [clarification needed] three weeks of wind tunnel testing of an 8%-scale model, with high AOAs up to 50° and 88° at very low speed, up from 13° in previous tunnel campaigns.

From 1974 to the mid-1980s, the United States government worked with industry to advance the technology and enable large commercial wind turbines. A series of NASA wind turbines were developed under a program to create a utility-scale wind turbine industry in the U.S., with funding from the National Science Foundation and later the United ...

A wind atlas contains data on the wind speed and wind direction in a region. [1] These data include maps , but also time series or frequency distributions . A climatological wind atlas covers hourly averages at a standard height (10 meters) over even longer periods (30 years) but depending on the application there are variations in averaging ...
Screenshot of the Global Wind Atlas website (version 2.2) The Global Wind Atlas is a web-based application developed to help policymakers and investors identify potential high-wind areas for wind power generation virtually anywhere in the world, and perform preliminary calculations. It provides free access to data on wind power density and wind ...
