The physics behind various wind tunnels were examined, and the most viable design was chosen. In terms of viability, the wind tunnel had to be designed so that it could be reasonable in size and could be built with materials that were reasonable in price. The open return wind tunnel is a type of tunnel where the air is pulled through the tunnel by a fan, rather than blown through it. There are four different sections to the wind tunnel: the inlet section, the contraction cone, the test area, and the fan section. The way to design the various sections of the wind tunnel were first researched, then altered so that they were of a viable size, and finally, actually built. When looking at different wing tips of a missile or a plane, the aerodynamics are very important for allowing it to fly farther, faster, and more efficiently. Using a wind tunnel allows the different designs of wing tips to be tested, giving the ability to the testers to determine the most efficient design, and thus a reliable wind tunnel is required.
