Abstract
THE fundamental question of the theoretical calculation of the effect of sweep on the distribution of lift across the span of a monoplane wing has, so far as the present writer is aware, been treated only by G. Andreoli and ?. M. Minski, the former paper being known to him unfortunately not in the original but only through a brief mention in the latter. Minski states that Andreoli approached the question by assuming the wing bound vortices curvilinear and passing through the locus of aerodynamic centres of the chords, the investigation being confined to very small deviations from the usual wing vortex system without sweep. However, it is alleged that the pursuit of the problem led finally to rather complicated integral equations insoluble in practice. Hence Minski, adopting the fundamental idea of a curvilinear bound vortex, this time passing through the mean C.P. positions of the chords (one‐third the chord length from the leading edge), proceeded to attack the problem by a somewhat different method, which will first be summarised briefly here since his paper, being in Russian, is presumably not generally known.
