Wind tunnels are basically the large sized tubes which hold the air moving inside. The wind tunnels are specially used to imitate the acts of objects in the flight. They are also used by the researchers to gain more knowledge about the flying of an aircraft. NASA makes use of these tunnels to examine or assess the scale models of the spacecrafts and aircrafts. Some of the wind tunnels are large in size that possess full-size version of the automobile. These tunnels move around the placed object and this process makes the viewer's feel like the object is actually flying.
Usually, the powerful fans move the air through the tube. The object or model that is to be tested is tightly and securely inside the tunnel, ensuring that it does not move during the entire process. The object can be as small as the copy of any vehicle, can also be a common article like a tennis ball, and also as big as a spacecraft and an aircraft. The moving air around the motionless object depicts that the object inside is really moving in the air. The air moving can be studied in several ways by the researchers and scientists. The dye or smoke can be observed as it moves inside. Threads can also be fixed to the object inside to view how the air moves.Major Key Players of the Wind Tunnel Testing Market are:
Boeing., Lockheed Martin Corporation., Aiolos, Aerolab LLC, HORIBA, Ltd., MAHLE GmbH, MITSUBISHI HEAVY INDUSTRIES, LTD., FKFS Forschungsinstitut für Kraftfahrwesen und Fahrzeugmotoren Stuttgart, HBM, ETW GmbH, and others.
