Using the Gasdynamic Knowledge Base for Aerodynamic Design and Optimization in the Sonic Speed Regime

ABSTRACT Refined concepts for high speed flow control in aerospace and turbomachinery applications suggest a retrospective look onto theoretical results of pre-CFD time for special airfoils, wings, bodies and internal flows because such results exhibit theoretically idealized behavior for some aspects in practical applications. Novel control mechanisms bring us closer to a mechanical realization of such special case studies. These provide known shape and (inviscid) flow properties in the transonic flow regime near Mach number unity, where numerical verification has always been a challenge to CFD and, for future generation SST concepts, an application to swept wings in supersonic flow.
