It’s 80 feet high, 120 feet wide, that’s large enough to hold a Boeing 737. Now trucking companies are using the wind tunnel to make their massive machines more efficient.
The biggest wind tunnel is the NASA Ames National Full-Scale wind tunnel in California. It’s able to accommodate planes with wing spans of up to 100 feet and nearly all commercial aircraft made in the United States since 1987 have been tested in this tunnel.
The tunnel can replicate the wind conditions of flight via six 22,500-horsepower motors with blades as tall as four-story buildings. It’s also used to test flight technology for space, such as parachutes for Mars missions.
