A Deformed Wake Model for Marine Propellers
Abstract
Results are given of a systematic series of experiments in which the radius and pitch of propeller tip vortices are measured and analyzed. The measurements of ultimate wake pitch are compared with theoretical predictions based both on a simple activator disc model and on a direct calculation of the self-induced velocities of the helical vortices. The effect of wake deformation on the computed radial distribution of pitch and camber is given for a specific design example.
