Topography Effect on the Aerial Navigation. I

[摘要] The phenomenon that the aeroplane seems to be repulsed when it approaches to a mountain and attracted when it crosses over a valley, is explained hydrodynamically by M. Sanuki.(2) In this paper, when we assume that a mountain-shape is conformally represented by the following conformal function, in which λ, α, β, γ are constants, we obtained approximately F (_??_) as the term of the “Topography Effect”, where, assumming the aeroplane as a point-vortex, _??_ is its co-ordinate. As an application, lift and drag above the summit of Mt. Huzi are calculated.
