Expansion tubes are an important type of test facility for the study of planetary entry flow- fields, being the only type of impulse facility capable of simulating the aerothermodynamics …
The cavity flameholder has been widely used in scramjets to improve mixing and combustion rates. While many have investigated modifications to the cavity downstream …
Surface roughness elements have been used to overcome the large prediction uncertainties of hypersonic boundary layer transition. They provide the ability to force transition at short …
This paper examines the scram/dual-mode combustion limits of hydrocabon fuels within a Mach 8, scramjet combustor. Flight-equivalent flows were delivered to the axisymmetric …
This paper presents the results of a series of shock tunnel experiments of a hydrocarbon- fuelled, Mach 8 shape-transitioning scramjet engine with a cavity combustor. The inlet of the …
Shock tunnel experiments are presented that examine combustion modes of ethylene and a 64/36% ethylene/methane mixture under Mach 8 flight-representative conditions within an …
This work examined combustion modes in a fundamental, axisymmetric, supersonic combustor at flight equivalent Mach numbers ranging from 7.5 to 9.0. Ethylene was injected …

The design and testing of a cavity flameholder in a Mach 8 rectangular-to-elliptical shape- transitioning scramjet is presented. The experimental results presented are from the shock …
Interactions between shock waves and boundary layers produce flow separations and augmented pressure/thermal loads in hypersonic flight. This study provides details of Mach …
