Wind tunnel are used for stimulating aerospace systems flight condition in the laboratory. Basically wind tunnel are characterized by their types, working function, dimension of test section, power, and speed. But the most important characteristic is wind speed. The hypersonic wind tunnel has Mach number from 5.0 to 10 (or 12). It’s a blow-down wind tunnel in which gas flow with high kinetic energy, it may exist thermal and chemical reaction behind the bow shock or with the boundary layer. This facilitates aerodynamic flow for research, development of a database parametric configuration studies and validation of codes and correlations. This paper will discuss some details about hypersonic wind tunnel structure and its facility in India. In addition, some issues associated with building hypersonic wind tunnels in the current environment of reducing T&E infrastructure by about 25 percent
