As the increasing pressure gradient is a cause of early transition from laminar to turbulent flow, it is necessary to make small the increasing pressure gradient along the surface. For this purpose the point of the maximum thickness of the aerofoil section must be shifted suitably backward. In the present paper the symmetrical aerofoil sections of such kinds were designed by the method of sources and sinks and the aerofoils with nearly uniform pressure distribution were obtained., 資料番号: SA4148262000}, pages = {462--478}, title = {Design of Symmetrical Aerofoil Sections Suitable for High Speeds.}, volume = {17}, year = {1942} }
