並列タイトル等Finite Element Calculations for Aerodynamic Coefficients of 3-Dimensional Body in Subsonic Flow Using Green’s Function Method
タイトル（掲載誌）航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-724
一般注記In recent years, finite element calculation schemes for the evaluation of aerodynamic loads have been developed using the Green’s function method. In these schemes, a set of linear algebraic equations is obtained by the discretization of the Fredholm integral equation of second kind, and is solved to yield values of velocity potential on the surface. The pressure on the surface is obstained by evaluating the derivatives of the velocity potential along the stream line. In this report, we propose an accurate method for evaluating the derivatives along circular paths on the surface. Calculations are made on various practical configurations such as wing-body combinations, tandem wings, wings with the dihedral angles at sideslip, ground effects, interference between a sphere and wind-tunnel etc. Comparisons with experiments show good agreement.
