PROPELLER TIP VORTEX IMPINGEMENT AND VIBRATORY FORCE ON A RUDDER

This thesis involves an experimental investigation of the phase relationship between the propeller tip vortex impingement and the vibratory force on a rudder. The experimental tests were performed in the MIT Variable Pressure Water Tunnel on a spade rudder in the wake of a five bladed propeller. The methodology of conducting the tests and obtaining the results is presented. The tests were conducted for various axial separations of the propeller and rudder. Graphical results of the phase, amplitude, moment, phase of the moment, and the centroid of the vibratory force are presented.
