Wind Tunnels Test Planes Without Flying



John Moss Wathen IV is a student of aerospace engineering. Having completed his degree in 2017, he is currently studying to become a pilot. In his studies, John Wathen IV has studied the technology used to test and assess new plane models.

Testing airplane models can be costly and risky in theory. If it were the case, the only way to test them was to take them for a flight. However, one way to test new airplane models that simulate flight with little risk is wind tunnel tests. A wind tunnel is a large tube containing an aircraft with powerful fans that push wind around the object in the middle.

The object, which is often a plane but could also be a piece of an aircraft or a miscellaneous object like a football, is secured in the middle of the tube, and scientists observe the movement of air around it using smoke or dye. The process of wind tunnel testing is not cheap, but if performed efficiently, it can be one of the quickest ways to test new models and subsequently improve performance.
