ABSTRACT	This paper presents an overview of numerical flow analyses past arbitrarily designed multi-element airfoils.Compressible unsteady inviscid flows aroung airfoils are analyzed by integrations of time-dependent Euler equations using finite difference tow around a symmetrical airfoil in a free-flight condition.Other calculations for a low-speed flow around a large thickness airfoil and variations with flap and spoiler were made in a wind tunnel boundary condition.Comparisons of pressure distributions and lift coefficients were also made with other calculated solutions and with experimental data.
