High-enthalpy hypersonic project at ONERA

This article deals with the research performed in the framework of the inte rnal ONERA Hyperenthalpic Hypersonic Project. This project involved fifteen researchers specialised in different domains, which are the following: fun damental studies on shock/wave and shock/boundary layers interactions; stud y of the laminar/turbulent transition; real gas effects and associated phys ical modelling; the development of non-intrusive optical diagnostic methods usable in cold and hot wind tunnels; dow rebuilding in a hot shot wind tun nel such as F4; conception, realisation and validation of computational flu id dynamics (CFD) solvers.
