I'm extremely sorry if you came here looking for the list,
Actually I wanted to ask if you have such a list/website.
I need a complete list.
and if you know it, will you please provide info about wind tunnels in Turkey.
One of Langley Research Center's most advanced facilities is the National Transonic Facility (NTF), which completed its first year of operation in 1984. In the NTF, super cold liquid nitrogen is injected and evaporated into a gas that is accelerated through the tunnel's test section at speeds up to 1.2 times the speed of sound. The low temperatures increase the density and decrease the viscosity of the atmosphere and, thus, simulate full-scale flight conditions at transonic speeds with great accuracy.
Another advanced Langley facility is the 8-Foot High Temperature Tunnel (8' HTT). This facility, which started operations in 1967, was constructed to verify flight-weight structure at Mach 7 flight conditions. The 8' HTT was removed from service in 1988 to add an oxygen enrichment system for scramjet testing. Langley Research Center has long been a major contributor to scramjet development.
A wind tunnel is often identified by the size of its test section, as opposed to the overall size of the tunnel. Test sections are the chambers in which aircraft models or other objects are tested. In a 13-inch research tunnel at Langley Research Center, experiments are underway using "magnetic suspension." Models are held in position with powerful magnets to eliminate the need for physical mounting mechanisms which interfere with the airflow or alter the model's geometry.
NASA's Lewis Research Center is know for its studies and innovations in aircraft propulsion systems. One of its wind tunnels, built in the 1950s, has a 10- by 10-foot test section in which aircraft models can be examined while their engines are running. In such tests, new air is continuously drawn into the tunnel and is then expelled after passing through the tunnel only once. The tunnel can also be operated in a mode like most other wind tunnels which circulate the same air repeatedly through their loops. In this way, a tunnel can better maintain high atmospheric pressure, desired temperatures or moisture content in its test section.
The 8- by 6-Foot Propulsion Research Tunnel at Lewis can push 150,000 pounds of air every minute across the test section at up to twice the speed of sound. In 1968, a 9- by 15-foot subsonic test section was added to that tunnel for research on surfaces and power plants of VISTOL (vertical and short-takeoff-and-landing) aircraft.
The Lewis Research Center's 6- by 9- by 20-Foot Icing Research Tunnel, built in 1944, is the world's largest refrigerated tunnel for year-round use to examine protection systems against hazardous ice formations on wings, air inlets, rotors and V/STOL aircraft.
The largest wind tunnel in the world is at NASA's Ames Research Center. This subsonic tunnel, which can test planes with wing spans of up to 100 feet, is over 1,400 feet long and 180 feet high. It has two test sections: one 80 feet high and 120 feet wide, the other 40 feet high and 80 feet wide. Air is driven through these test sections by six 15-bladed fans. Each fan has a diameter equal to the height of a four-story building. The fans are powered by six 22,500-horsepower motors.
The Ames and Langley Research Centers each have a "Unitary Plan Facility." The Ames facility opened in 1956, with three test sections--a transonic section that is 11 feet wide by 11 feet high, and two supersonic sections, that measure 9 feet by 7 feet and 8 feet by 7 feet. In these sections, the air can be adjusted to simulate flying conditions at various altitudes. The computer age has allowed researchers to take a new look at improving wind tunnel data normally available at transonic speeds. The installation of computer-controlled walls allows air to be automatically added or expelled from the tunnel walls. This lessens interference on the airflow by the walls. Thus, the wind tunnel can more realistically simulate conditions of an aircraft in the open, wall-free natural flight environment.
Similar advantages are being pursued at the Lewis and Langley Centers, where engineers are experimenting with various kinds of "adaptive walls" or "smart walls." These expand and contract in ingenious ways to virtually remove the distorting effects walls can have on a tunnel's airflow. Langley's 0.3-Meter Transonic Cryogenic Tunnel has an adaptive wall test section that has been operational since March 1986.
Marshall Space Flight Center's 14- by 14-Inch Transonic Wind Facility got its name because it can conduct tests in three speed regimes, from subsonic through transonic to supersonic. This means it can test in ranges from 1.5 to five times the speed of sound.
The Department of Defense operates several major wind tunnels, as do some U.S. industries and universities. Nations which have major wind tunnels listed in NASA's "Aeronautical Facilities Catalogue" include the United Kingdom, 27; France, 18; Japan, 16; West Germany, 11; the Netherlands. 4; and Canada, 5.
NASA's wind tunnels are a national technological resource. They have provided vast knowledge that has contributed to the development and advancement of the nation's aviation industry, space program, economy and the national security. Amid today's increasingly fierce international, commercial and technological competition, NASA's wind tunnels are crucial tools for helping the United States retain its global leadership in aviation and space flight.
that what i got from google. Nothing got about turkey.
