INFLUENCE OF THE PROPELLER ON THE TRANSVERSE FORCE AND YAWING MOMENT OF SHIPS

This is an abridged version of a Rostock University thesis. Propeller-induced transverse forces and yawing moments at the stern affect a ship's manoeuvring behaviour and steerability. These effects of the propeller, their calculation by methods based on those given in the literature, and measurements (in a rotating-arm basin) confirming the theoretical results, are discussed, and some conclusions are drawn, under the main headings 1) Propeller Forces and Moments (Assumptions--Calculation Method--Velocity distribution--Transverse Force and Yawing Moment at the Propeller). 2) Transverse Force and Yawing Moment from the Rudder working in the propeller Slipstream (Assumptions--Calculation of Transverse Rudder-Force--Transverse-Force and Yawing-Moment Coefficients for the Rubber in the Slipsteam). 3) Transverse Force on the Stern (Origin of the Transverse Force on the Stern--Calculation Method--Transverse Velocity--Transverse-Force and Yawing-Moment Coefficients). 4) Experimental Investigations on Propeller Influence (Model, and Measurement Programme--Analysis of Measurements--Comparsison with Calculated Results).
