With relation to the main problems in hypersonic aerothermodynamic and aerodynamic research are reviewed. To develop useful design tools for re-entry vehicles, a balanced combination of computational fluid dynamics, wind tunnel experiments, and free flight tests is needed. A flight test facility can be simple and cost effective if flown as piggyback in the second stage of Ariane 4. It is shown that high-enthalpy hypersonic wind tunnels are unable to reproduce the main simulation parameters of hypersonic flow simultaneously. These ground-based facilities provide predissociated flow immediately upstream of test models due to the nozzle-relaxation effects.
