Zirconium‐Based High Emissivity Multilayer Coating for Carbon/Carbon Composite With Enhanced Ablation Resistance

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
ABSTRACT A multilayer coating system was developed as an ablation and thermal protection measure for C/C composites. The multilayer coating architecture consists of SiC, ZrB2‐SiC (ZBS), and ZrC‐ZrO2 (ZZC) sublayers with a Sm2O3‐ZrO2 (SZC) topcoat.

Numerical and Experimental Investigations of a Generic Rocket Launcher Configuration with Cold Plume in Hypersonic Flow

, 2013
A generic rocket launcher geometry is studied experimentally and numerically at hypersonic flow conditions including a cold plume. The experiments are conducted in a hypersonic Ludwieg tube while numerical calculations are performed with a finite-volume

Transpiration Cooling Tests of Porous CMC in Hypersonic Flow

, 2011
During hypersonic flight the temperatures on the vehicle can reach very high values in certain locations. A hypersonic flight vehicle needs to be designed aerodynamically efficient. That results in rather small nose and leading edge radii which drives up

Hypersonic control effectiveness

, 1995
The present study analyses the effects of a number of geometric parameters on the performance of a trailing edge control flap on a hypersonic body. The tests were conducted in a gun tunnel at Mach 8.2 and Mach 12.3.

Influence of boundary layer transition on the trajectory optimisation of a reusable launch vehicle

, 2014
Based on flight experience from the Space Shuttle programme, it is well known that mis-prediction of the effects of boundary layer transition represents one of the highest technical risks when designing a Reusable Launch Vehicle.

Future Prospects for Hypersonic Flight Test For University Students

, 2005
The transport to space of satellites and experiments with conventional expandable rockets is a very expensive and time demanding business and therefore almost prohibitive for Universities and High-School or Colleges laboratories.
