This report concerns the kinematics of the motion of trailing vortex sheets in the wake of a propeller and the dynamics of the tip vortex. The problem is solved numerically for a lifting line wing model and the results applied to propeller theory. Special consideration is given to the subjects of tip vortex cavitation, changes in loading on a blade due to rollup of the trailing vortex sheet, and the trajectory of the tip vortex. Experimental confirmation was obtained for the pressure at which cavitation appeared and the motion of the vortex sheet through testing a hydrofoil in a propeller tunnel.
