A sample wind tunnel layout showing some typical features including a test section and control room, a machine for pumping air continuously through ducting, and a nozzle for setting the test airspeed.
The power required to run a supersonic wind tunnel is enormous, of the order of 50 MW per square meter of test section cross-sectional area. For this reason most wind tunnels operate intermittently using energy stored in high-pressure tanks.
Hoover Inc. announced a recall of its Hoover WindTunnel bagless upright vacuums after receiving reports of the machines burning carpets and a consumer's hand, the U.S. Consumer Product Safety ...

16S is a supersonic wind tunnel that can be configured for Mach numbers from 1.5 to 4.750. The test section is also 16-foot-square and 40-foot long. The facility can simulate unit Reynolds numbers from approximately 0.1 to 2.4 million per foot or altitude conditions from 43,000 to 154,000 feet.

Transonic wind tunnels, between Mach 0.75 and Mach 1.2 (920 and 1,500 km/h; 570 and 910 mph; 260 and 410 m/s), are designed on similar principles as subsonic tunnels but present additional challenges, primarily due to the reflection of shock waves from the walls of the test section.
