Since the end of World War II the interest in high-velocity aerodynamic technologies has grown significantly and research in hypersonic flows has become a strategic field of study. These developments have led to the engineering of heat shields used atmospheric entry modules, providing thermal protection to the crew and space probes, but also to the design of scramjet propulsion system. Clearly the military industry has got a substantial support in the production of long range and high speed weapons, such as hypersonic cruise missiles. Experimental analysis remains a fundamental pillar in design and test processes of hypersonic technologies, however this approach requires appropriate testing facilities which have significant operational costs.
