PROPELLER EXCITED HULL AND RUDDER FORCE MEASUREMENTS

Measurements of the blade frequency vibration forces acting on the hull and rudder of a flat stern self-propelled model and water tunnel measurements of propeller-induced rudder forces are presented. Both types of experiments confirm the extreme sensitivity of vibratory force amplitudes to axial clearance between the rudder and propeller, and on the relative position of the bottom of the rudder with respect to the propeller lower tip vortex.
