Note (General): A method of obtaning subsonic unsteady aerodynamic forces in the Laplace domain is presented in this paper. The kernel function of singular integral equations based on the lifting surface theory is numerically computed in the exact way for the entire s-plane. In an example calculation of the generalized forces, a singularity appears in the left half of the p-plane at a high Mach number of eight-tenths. It is shown that the singularity is a pole of the order one and that it can be modeled by a simple rational function which is relevant to the aeroelastic analysis. The theory of functions is utilized for obtaining the singularity model for the generalized forces.
