It consists of a collection of menu-driven routines which perform various useful functions such as: * Viscous (or inviscid) analysis of an existing airfoil * Airfoil design and redesign by interactive modification of surface speed distributions * Airfoil redesign by interactive modification of geometric parameters * Blending of airfoils * Writing and reading of airfoil coordinates and polar save files * Plotting of geometry, pressure distributions, and multiple polars </longdescription> </pkgmetadata>
