Abstract : A progress report is given on three related projects, in all of which elliptic equation are used to describe shear layers with significant upstream influence, such as occurs near trailing edges or rapid changes in surface curvature. The large computing times usually required for iterative elliptic solutions are avoided, or disguised, by imbedding the shear layer iteration in the iteration loop required to match any shear layer solution to a solution for the outer 'inviscid' flow. Programs for calculation of flow over single airfoils are running in imcompressible and compressible flow (in the latter case with moderate shock induced separation) and extension to multi element airfoils is in hand.
