Abstract
A method of designing hydrodynamic sections having improved characteristics is described wherein a desired pressure profile and boundary layer conditions for the surface of an undefined section are established at operating velocities for the section and a hydrodynamic section is analytically designed to provide the desired characteristics. One preferred embodiment of the hydrodynamic section meeting the established pressure profile and boundary layer conditions is disclosed having a flat bottom and upper surface defined by a plurality of circular arcs.
