翼平面形 kink による揚力分布特異性の簡易完成型表現

抄録

Convergence of lifting surface numerical computations with mode method would be generally deteriorated by kinks, especially on the leading edge, of wing planforms. The intrinsic cure should be brought about by the appropriate mode function (eigensolution) for the kinks, rather than “rounding off” of the kink, although the latter has often readily been used. A new unified formula of eigensolution is developed through results of a series of numerical computations with discrete lifting surface scheme “BIS.” But the parameters appearing in this formula were determined by using the results of previous analytical solutions obtained by other authors, because of their superior accuracy.
