Investigations on the maximum limit of the circulatory lift for the conventional wing with the high aspect ratio have already been published in several papers, however, the analyses in those papers are limited almost to the case of the elliptical circulation distribution along the wing span.
In this paper, the aerodynamic forces on the wing are analyzed theoretically for the cases of the various spanwise circulation distributions, not to mention the elliptical form, by using a proper form function, and the effects of the distribution form on the maximum limit value of the lift, the lift/drag ratio, and so on, are investigated. Moreover, in connection with these problems, this paper deals with the theoretical analyses concerning the structures of a pair of rolling up vortices with the cores existing in the infinite distance behind the wing. The results obtained in the present paper may be used as the available data for the investigation of the lift augmentation of the short take-off and landing airplane.
