Abstract

The inlet is the component of an airbreathing vehicle responsible for bringing atmospheric air to a ramjet, turbojet, or turbofan engine. An inlet flow distortion at the outflow boundary in a submerged subsonic inlet was analyzed and compared with the computation to ascertain the accuracy of the computations. The introduction of fins inside the inlet reduces the DC by creating a secondary flow that counteracts the swirl caused by the boundary layer separation and crossflow pressure gradient. The experimental study further extended to investigate the dependence of the flow structure on the angle of sideslip.
