A boundary element method has been developed for the evaluation of steady aerodynamic loads acting on complex configurations in subsonic flow. By means of Morino's method, the integral equation, which is made from differential equations of fluid motion using Green's formula, is transformed into a set of linear algebraic equations for numerical calculatios. The velocity at an arbitrary point on a body surface is given by the derivative of velocity potential at the point along surface stream line. The purpose of this investigation is to calculate aerodynamic loads acting on the complex configurations using the boundary element method. Aerodynamic quantities, such as pressure distributions, lift, drag, and pitching moment of a speceplane, are calculated.
