Researchers use wind tunnels to test models of proposed aircraft. We can precisely manage the flow conditions in the tunnel, which affect the aircraft's forces. We can forecast the forces on the full-scale aircraft by carefully measuring the forces on the model. We can also better understand and improve the aircraft's performance by employing special diagnostic techniques. There are several different types of wind tunnels and model instrumentation, each intended for a unique function and speed range. In this wind tunnel, the flow of air is assumed to be steady and incompressible. This paper explains about design and working process of Subsonic wind tunnel testing.
