APPARATUS FOR PREVENTING LIFT FORCE REDUCTION BY RUDDER-TIP VORTEX

摘要

The present apparatus is related to an apparatus for preventing lift force reduction by the vortex in a rudder (20) moving to free flow (11). The apparatus is installed with a plurality of spray holes (30) on the lower surface of the rudder (20) and to delay a point of that the exfoliation (13) is generated by spraying water-jet (35) to the spray hole (30). Accordingly, it is possible to enhance maneuverability by reduction of the resistance and the increase of the lift force of the rudder by delaying the point of the exfoliation generated due to the interaction weakening between the rudder tip vortex and the free flow.
