This paper deals with a numerical and experimental activity for the development and integration of the aerodynamic database of hypersonic test vehicle in the framework of the H2020 More&Less project. At this purpose, a dedicated methodology has been developed and applied to several supersonic/hypersonic vehicles. This methodology foresees the development of aerodynamic aerodatabases by means of incremental steps starting from simplified methods up to very reliable data based on high fidelity CFD simulations and experimental measurements with associated confidence levels. In particular in this paper a direct comparison between CFD results and experimental measurements is reported being this a fundamental step for the building of the final aerodynamic database of the Mach 5 flying experimental vehicle (flying test bed).
