Abstract: This paper reveals the exploration of applying the Barchane Dune vortex generator-a new kind flameholder in a ramjet.Although some technical problemsstill need to be solved experimental results show that the Barchane Dune vortexgenerator is superior to the V-gutter in ignition, stable combustion, combustionefficiency and flow dragloss as used in ramjet.The decrease of flow dragloss makes the critical thrust of ramjet increase about 6-9% .
