In the former approach, the exact expressions of lift and lift distribution are obtained in terms of Fresnel integrals, while in the latter approach an integral equation must bc solved, the kernel function of which is obtained from the subsonic Possio's equation and has a root singularity. The discrete analysis is adopted on the basis of the semi-circle method (SCM) and the weighting function for subsonic-flow-Gauss'-quadrature, as well as modified diagonal elements resulting from the root singularity. Aerodynamic characteristics obtained from both approaches agree quite well with each other. The results obtained by the present computations are compared with those of DLM-C (subsonic 2D code) developed by ANDO et al, and are found to give a reasonable outer boundary for subsonic unsteady aerodynamics., 資料番号: NALSP0005016, レポート番号: NAL SP-5},
