Abstract

The paper proposes an overview of the physical models developed/selected and implemented in the ONERA aerothermodynamic (ATD) engineering code FAST. This tool is used to quickly determine the pressure and heat flux surface distribution at the wall, as well as aerodynamic forces and moments coefficients in hypersonic regime for free-molecular, transitional and continuum flows, for realistic designs of space vehicles ranging from capsules to spacecrafts and for generic shapes of orbital debris as well. An original feature of the approach is that geometrical components of the object are not separately processed but are investigated by a global method taking into account geometrical effects and flow history (shadow regions, surface heat flux propagation). Several application cases are displayed to rely on the engineering approach: ARD and AOTV capsules, Pre-X (an IXV-like vehicle) and CubeSat (a debris-like single object). The given results have been analysed by comparison with experimental and CFD data. The limits of the approach are discussed, paving the way for future developments.
