The Aerodynamics of a Jet in a Crossflow

Abstract

The aerodynamics of a jet in a crossflow considered as the key problem in transition aerodynamics for VSTOL aircraft has been reviewed. Experimental results on the flow structure of the jet, the contrarotating vortices, the jet entrainment phenomenon, and the surface pressure distributions have been analyzed. The influences on these characteristics by the jet parameters such as the velocity ratio, injection angle and jet orifice shape have been considered based on available measurements. In the theoretical area, particular attention has been directed to the methods of prediction and analysis, and the fundamental physical bases of these methods. Current developments in transition aerodynamics, and some recent work on the formation of contrarotating vortices and the wake flow are described.
