Note (General): A boundary element method for the evaluations of steady aerodynamic loads around complex configurations in subsonic flow has been developed using Green’s function. Morino described the form of the integral equation, which is transformed into a set of linear algebric equations. The velocity on the arbitrary point of the body surface is given by the derivative of the velocity potential on the point along the surface stream line. The purpose of this paper is to present a new paneling and derivative technique which can be applied to any complex configuration. To evaluate the derivative of velocity potential on the surface, the surface element is replaced with the circular arc, which is determined by three collocation points in adjoining panels. Aerodynamic quantities, such as pressure distributions, lift, pitching moment and drag of the actual airplane in compressible flow, are calculated as an example. Comparisons between numerical and experimental results show good agreement.
