RUDDERS IN THE REGION OF INFLUENCE OF A DUCTED PROPELLER

Previous work at the VBD has provided information on the influence that the hull (in particular the stern form), and the arrangement of the rudder in relation to the propeller, exert upon rudder forces and moments. Further model investigations associated with this problem have been carried out with four different rudders (designed for inland-waterways vessels), and the present report, after a discussion of the problem, gives an account of this later work, together with detailed results for one of the rudders; this rudder was of a type normally fitted to a pusher tug with a ducted propeller. Several conclusions are drawn on the influence of the ducted propeller on the rudder forces and moments. The experiments also show that every rudder design should have individual treatment; the rudder itself, and above all the total system consisting of the ship, ducted propeller, and rudder, must be considered, and conditions when going astern must not be overlooked.
