Simulation of the aerothermal environment experienced by space vehicles during atmospheric reentry can be performed by arc-jet facilities, which generate high enthalpy hypersonic flows for long time. Such is the case of Small Planetary Entry Simulator (SPES) at the Department of Aerospace Engineering of University of Naples (DIAS), described in the paper. To support arc-jet tests within SPES it is important to dispose of a simple tool which evaluates all aerothermodynamic flow properties by using the few experimental measurements available and a chemical model of the high enthalpy flow. In the paper we present the model implemented and used for arc-jet tests performed for AVIO company, to evaluated performances of its thermal protection material for the European space vehicle named IXV.

Abstract
Simulation of the aerothermal environment experienced by space vehicles during atmospheric reentry can be performed by arc-jet facilities, which generate high enthalpy hypersonic flows for long time. Such is the case of Small Planetary Entry Simulator (SPES) at the Department of Aerospace Engineering of University of Naples (DIAS), described in the paper. To support arc-jet tests within SPES it is important to dispose of a simple tool which evaluates all aerothermodynamic flow properties by using the few experimental measurements available and a chemical model of the high enthalpy flow. In the paper we present the model implemented and used for arc-jet tests performed for AVIO company, to evaluated performances of its thermal protection material for the European space vehicle named IXV.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
