Calculation of Hydrofoil Sections from Prescribed Pressure Distributions

摘要

The paper may be regarded as a manual for the design of hydrofoils or airfoils from specifications on the pressure distributions. This design procedure employs the well-known theories of incompressible, inviscid, steady flow and conformal transformations. A profile design is begun by tentatively specifying the pressure distribution desired at selected angles of attack. These specifications which usually conflict with each other are reconciled so as to correspond to an existing but unknown profile. The coordinates of the section are then accurately and rapidly calculated. The purpose of the paper is to give a connected and detailed development of both theory and numerical procedure in the hope that this useful profile design method may find more general application.
