Modern Wind TunnelsInlet diffuser of a wind tunnel at NASA AmesResearch Center. The inlet diffuser works like thegrid that was used for “straightening” the wind inthe Wright tunnel. Ames has the world’s largest windtunnel at its site in California.Propulsion fan (like the fan to create airflow in the Wright tunnel)of the Transonic Wind Tunnel at NASA Langley Research Center (thefan blades of this older tunnel are made of wood). The first majorU.S. wind tunnel was built at Langley in 1920.Test section of a supersonic (high flight speed) wind tunnel at NASAGlenn Research Center. The white “lines” are laser beams thatengineers use to measure the performance of the model. The Wrightsused a bicycle-spoke balance to do the same job in their tunnel. Aresearcher is peering in at a window just as the Wrights did.Activity 11—The Wrights’ Wind TunnelThe Wright Brothers are credited with a number of “firsts” in the science of aeronautics. One of these firsts wasusing a wind tunnel of their own design (a 6-foot-long rectangular box) to gather data and to design wing shapes(called airfoils). Wind tunnels are still used for many kinds of research. Some of them are very large; some aresupersonic; some are very cold; and some simulate very high altitudes.1. Why did the Wrights construct their own wind tunnel?2. When they ran their tests, the Wrights only allowed one person in the room and that person always had tostand in exactly the same place. Why do you think they had to take this precaution?Learning to Fly: The Wright Brothers’ Adventure EG–2002–12–007–GRC21
3. A grid was placed in the end of the box where the air entered. What function would you guess this served?4. What advantages are there to testing airfoils in a small box? (Try to list at least three.)you were to try to get good data on which wing worked the best, which of the following designs do you think5. If you were to try to get good data on how well a wing design worked, which of the following wind tunnelarrangements do you think would be best?A.B.C.D.What factors made you decide on this as the best design?Learning to Fly: The Wright Brothers’ Adventure22EG–2002–12–007–GRC
