Bookmark or Share- Wind tunnel - Wikipedia16-foot supersonic wind tunnel at Arnold Air Force Base, 1960. A model Cessna with helium-filled bubbles showing pathlines of the wingtip vortices. 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.
- How does a wind tunnel work? - Explain that StuffThere's nothing to stop you building a super-giant wind tunnel and testing a life-sized model of your plane—and, indeed, the American space agency NASA does have wind tunnels like this. But most of the time it's much cheaper to use a small, scale model of the plane in a much smaller wind tunnel.
- Beginner's Guide to Wind Tunnels - NASASome of the topics included are: history of wind tunnels; design and operation of wind tunnels; construction of wind tunnels; instrumentation and models; and the underlying similarity principles that enable wind tunnel testing. Many of these principles are related to the fundamental study of aerodynamics.
- How Wind Tunnels Work - HowStuffWorksKey Takeaways. From aircraft and cars to industrial and consumer products, wind tunnels are crucial for testing the aerodynamics of various objects, allowing for improvements in safety, efficiency and performance. These large, hollow tubes create controlled wind conditions to study objects' behavior in airflow.
- What Are Wind Tunnels? (Grades K-4) - NASAWind 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 aircraft and spacecraft.
