On the design of lifting airfoils with high critical Mach number using full potential theory (Q1371498)

The paper discusses the problem of designing lifting airfoils at critical Mach number in a framework of compressible potential flow. The given mehod uses the hodograph plane to construct airfoils with long segments of sonic arc connected to straight line segments at the tail, and a nose portion that has a given velocity distribution. To construct lifting airfoils, the author assumes that an airfoil has the longest possible arc length of sonic velocity over its upper and lower surface. A wide variety of lifting airfoils are constructed. It will be noted that in order to have a truly practical interest, airfoil design procedure must include viscous and separation effects.
