AERODYNAMICS AND AEROTHERMODYNAMICS ANALYSES OF A EARTH-RE-ENTRY CAPSULE FOR SAMPLE RETURN MISSION IN THE FRAMEWORK OF RASTAS SPEAR PROJECT
This paper deals with the computational fluid dynamics analysis of a capsule entering the Earthatmosphere, at the end of a sample return mission. Several two-dimensional axis-symmetricsimulations have been performed to assess the flowfield environment past a sphere-cone capsule,by using non-equilibrium reacting gas approximations. Heat shield ablation and effects of flowplasma radiation on capsule aeroheating are also accounted for, also if in a non-coupled approachwith the flowfield analysis. the issue of aerodynamic and aerothermodynamic performance of theentry spacecraft in the framework of a super-orbital re-entry scenario is addressed.
