Abstract

An analytical investigation was made of incompressible potential flow fields in which the velocity components are homogeneous of order zero. Superpositions of such fields were then made and expressions were derived for the flow fields associated with constant-strength source and vortex sheets of finite extent.

The constant strength source-sheets were then applied to the construction of aerodynamic models of thin non-lifting wings of polygonal platform and airfoil section.

By use of the constant strength vortex-sheets, several approximate aerodynamic models were constructed for the determination of the pressure distribution on thin lifting wings at small angles of attack.
