Abstract: Abstract: - The paper presents a boundary element approach for the problem of the finite span airfoil in a subsonic compressible fluid flow. The singular boundary integral equation equivalent with the mathematical model characterized by partial differential equation is solved in this paper by the use of constant and linear isoparametric boundary elements of Lagrangean type. A special attention is given to the treatment of the singular integrals because their evaluation major influences the numerical solutions accuracy. Some aspects about how to treat the integrals of singular kernels in case of solving 3D problems are presented. An efficient method that is applied consists in using suitable geometrical transformations of coordinates to eliminate the singularities. A computer code based on this method is made and numerical results are obtained. The computer code is tested by making an analytical checking and the results show the efficiency of the method.
