Numerical/Experimental Correlation of a Plasma Wind Tunnel Test on a UHTC-Made Nose Cap of a Reentry Vehicle

UHTC‐Based Hot Structures

“…As a result of the Nose_1 test results, Nose_2 fabrication was delayed and the attachment concept between tip and base was redesigned. In particular, the mechanical interface between the monolithic tip and the C/SiC base was changed to a metallic fastener preloaded with a spring, which avoided the use of any threaded pivot or hole [60]. The concept of the coupling pin is as follows: the pin is introduced into the hole and then rotated by 90° to ensure contact.…”

SCIROCCO Plasma Wind Tunnel: Synergy between Numerical and Experimental Activities for Tests on Aerospace Structures

“…Destructive inspections confirmed later that the coating was locally detached by the outer dome in several zones. Further investigations were made during the rebuilding phase of a second PWT test performed on the same nose cap demonstrator (Borrelli et al, 2010). Experimental data were compared with numerical results in order to help in interpreting the experimental test itself.…”

Thermo-Structural Behaviour Prediction of the Nose Cap of a Hypersonic Vehicle Based on Multifield Coupling

“…When the nose cap is subjected to the aerothermodynamic loads, high temperature of the structure will cause the change of material physical parameters and large temperature gradient will result in thermal stress and deformation. In addition, the structural deformation will affect the heat flux and pressure distributions along the wall of the structure, thus forming a complex thermo-mechanical coupling issue [5,6]. Therefore, it is necessary to establish a fluid-thermal-structural coupling model to predict the hypersonic flow field, transient temperature, and deformation of the nose cap.…”
