16th AIAA/DLR/DGLR International Space Planes and Hypersonic Systems and Technologies Conference, 2009
An investigation is undertaken into the potential use of carbon-carbon materials for Scramjet combustors and configurations utilising regenerative and radiative cooling are considered. The analysis uses the ANSYS package to couple a CFD analysis of the fuel cooling with a structural thermal analysis.

Noise Generated in a Scramjet Combustor
AIAA SCITECH 2023 Forum, 2023This paper presents the noise levels generated inside a two-dimensional scramjet combustor at Mach 7.3 freestream using the focused laser differential interferometric (FLDI) technique. FLDI measurements were taken at the front, middle, and rear of the combustor’s center plane under unfueled, combustion-suppressed, and combustion-on conditions ...
