A Plume Cross-Sectional Shape of Transverse Helium Injection Having Weakly Penetration into a Supersonic Boundary Layer by a Porous Injector

摘要

This is a basic experimental study about SHSIrnignition system for hydrocarbon-fueled small scramjetrnengine. The gaseous helium, a simulant of hydrogenrnbeing ignition source, is supplied through porousrnmetal with low dynamic pressure. The helium streak isrnadhered the wall and stayed within boundary layer.rnBaroclinic torque is able to lift up this streakrnsuccessfully.
