The Use of Polynomial Source and Doublet Distributions in Generating the Lifting Characteristics of Axi-Symmetric Bodies: Boundary Layer Influence

摘要

An extension of a method developed for determining the potential flow around lifting bodies of revolution in uniform, incompressible, flow is presented. This technique uses axial, polynomial, distributions of both sources and doublets. The displacement surface of the boundary layer on a body, and the potential flow around this surface are iteratively determined. The validity of this approach was investigated, and comparisons made with a panel technique and very limited available experimental data. The method provides improved estimation of the lifting characteristics without resort to empiricism.
