Numerical simulations of a 2D axisymmetric aerodisked nose cone in hypersonic flow are
conducted, and innovative techniques involving forward injection of the gas from the …

In this study, a multilayer thermal protection system (TPS) of hollow cylindrical structure for
hypersonic flight vehicles (HFVs) is modeled and its thermo-mechanical responses are …

I. Introduction ver the last years, innovative concepts of civil high-speed transportation
vehicles were propose d 1, 2. These vehicles have a strong potential to increase the cruise …

IVIL high-speed transportation has always been hampered by the lack of range potential or
a too high fuel consumption stemming from a too low cruise efficiency. Indeed, looking into …

Abstract A Forward-Facing Step (FFS) can be approximated as a simplified geometry for
modeling the irregularities around space vehicles, the flow around which is often rarefied …

The aero-thermal analysis of a hypersonic vehicle is of fundamental interest for designing its
thermal protection system. The aero-thermal environment predictions over several critical …

Hypersonic vehicles with Mach numbers greater than five exhibit complex shock wave
interactions, accompanied by locally enhanced heat flux near the shock-affected surface. To …

Abstract SPREAD (Scramjet PREliminary Aerothermodynamic Design) is a simplified, in-
house method developed by CIRA (Italian Aerospace Research Centre), able to provide a …

This study investigated and modeled the transient behavior of surface recession, defined as
the difference between ablative length and swelling length, for thermal protection materials …

Purpose For a thermal protection system (TPS) of long endurance hypersonic flight vehicle
(HFV), its thermal insulation property not only determines by the manufactured morphology …
