Review of Experiments on Ignition and Flameholding in Supersonic Flow

5.1 ABSTRACT Supersonic combustion data obtained at the low static temperatures appropriate for an efficient scramjet engine are reviewed. Attention is directed at the methods by which the fuel was ignited and combustion maintained. The cited supersonic combustion experiments are grouped under the six headings: chemical intiators; non-uniform flows; turbulent flameholding; combustion induced compression; partial subsonic combustion and plasma sources. The paper is drawn from the NATO RTO AVT WG10 report on technologies for propelled hypersonic flight which aims to summarise the state of the art, identifying the key issues still hindering scramjet development.
