FULL-SCALE CAVITATION OBSERVATION ON LARGE DUCTED PROPELLERS

The case in favor of ducted propellers, as shown by increases in propulsive efficiency and maneuverability at large rudder angles, has been proven, but a question as to cavitation and erosion characteristics remains. This article reports on cavitation tests, both model and full-scale, which were performed on a variety of ship types, including VLCC's, an ore carrier and an LPG carrier. The experimental apparatus, the tests which were performed and the conclusions which were reached, are all discussed.
