Wind tunnel - Wikipedia
网页Wind tunnels are machines in which objects are held stationary inside a tube, and air is blown around it to study the interaction between the object and the moving air. They are used to test the aerodynamic effects of aircraft, rockets, cars, and buildings.
What Are Wind Tunnels? (Grades K-4) - NASA
网页2017年4月5日 · Wind tunnels are large tubes with air moving inside. The tunnels are used to copy the actions of an object in flight. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of …
How Wind Tunnels Work - HowStuffWorks
网页2024年4月16日 · Utilities managers use wind tunnels to test wind turbines used to generate electricity. Wind tunnels help make the turbines and their blades more efficient, effective and durable, so they can withstand constant, powerful gusts.
Wind tunnel | Aeronautical Engineering Benefits | Britannica
网页Wind tunnel, device for producing a controlled stream of air in order to study the effects of movement through air or resistance to moving air on models of aircraft and other machines and objects. Provided that the airstream is properly controlled, it is immaterial whether the stationary model.
Wind Tunnel | Glenn Research Center | NASA
网页2023年1月21日 · Wind Tunnel. At the end of 1901, the Wright brothers were frustrated by the flight tests of their 1900 and 1901 gliders. The aircraft were flown frequently up to 300 feet in a single glide. But neither aircraft performed as well as predicted using the design methods available to the brothers.
Beginner's Guide to Wind Tunnels - NASA
网页2023年2月27日 · A wind tunnel is a machine which can simulate the movement of air around an aircraft in flight. In the wind tunnel, the aeronautical engineer can control the conditions that effect the forces and motion of the aircraft.
Testing on the Ground Before You Fly: Wind Tunnels at NASA Ames
网页2020年5月21日 · During a test, wind tunnel engineers measure how the design responds “in flight,” observing its stability, aerodynamic performance and more. Wind tunnels are where an aircraft gets its first safety checks, before it takes to the sky.
How does a wind tunnel work? - Explain that Stuff
网页2023年7月27日 · Although wind tunnels are best known for testing out new planes and space rockets—vehicles that speed through a (theoretically) static airstream—they can also be used in the opposite way: to simulate how fast-moving winds affect static structures, such as high-rise buildings and bridges.
Types of Wind Tunnels - NASA
网页2021年5月13日 · Types of Wind Tunnels. Aerodynamicists use wind tunnels to test models of proposed aircraft. In the tunnel, the engineer can carefully control the flow conditions which affect forces on the aircraft. By making careful measurements of the forces on the model, the engineer can predict the forces on the full scale aircraft.
Starship Super Heavy Breezes Through Wind Tunnel Testing at …
网页2024年9月10日 · The wind tunnel subjected the Super Heavy model, affixed with pressure-measuring sensors, to wind speeds ranging from Mach .7, or about 537 miles per hour, to Mach 1.4, or about 1,074 miles per hour. Mach 1 is the speed that sound waves travel, or 761 miles per hour, at sea level.
