Hypersonic interference heating in the vicinity of surface protuberances [PDF]

, 2010
The understanding of the behaviour of the flow around surface protuberances in hypersonic vehicles is developed and an engineering approach to predict the location and magnitude of the highest heat transfer rates in their vicinity is presented.

Robust multi-disciplinary design and optimisation of a reusable launch vehicle

, 2014
For various technical reasons, no fully reusable launch vehicle has ever been successfully constructed or operated. Nonetheless, a range of reusable hypersonic vehicles is currently being considered as a viable alternative to the expensive but more ...

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.

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.

Discrete-Roughness Transition for Hypersonic Flight Vehicles [PDF]

Journal of Spacecraft and Rockets, 2007
The importance of discrete roughness and the correlations developed to predict the onset of boundary layer transition on hypersonic flight vehicles are discussed. The paper is organized by hypersonic vehicle applications characterized in a general sense by the boundary layer: slender with hypersonic conditions at the edge of the boundary layer ...

Effect of Sintering Aid Composition and Porosity on the Oxyacetylene Torch Response of Silicon Nitride for RF Windows

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Silicon nitride samples were slip cast using yttrium oxide–aluminum oxide and ytterbium oxide sintering aids to fabricate plates with up to 40% porosity and compare them to a fully dense commercial standard. Silicon nitride plates were tested with an oxyacetylene torch to investigate changes in front and back face temperature, spectral emissivity ...

A case study on the aerodynamic heating of a hypersonic vehicle [PDF]

, 2012
A Parabolised Navier-Stokes (PNS) flow solver is used to predict the aerodynamic heating on the surface of a hypersonic vehicle. This case study highlights some of the main heat flux sensitivies to various conditions for a full-scale vehicle and ...

Shock‐Assisted Flow Control System in Convergent‐Divergent Nozzle: A Numerical Study on Unconventional Protuberance With Different Geometry

Engineering Reports, Volume 8, Issue 5, May 2026.
A numerical investigation using 3D RANS simulations demonstrates significant effects of protuberance geometry—cubic, cylindrical, spherical, and conical—on shock‐induced thrust vectoring in supersonic nozzles. Cubic protuberances provide the maximum jet deflection (˜2°) with negligible thrust reduction.
