CAVITATION AND VENTILATION OF A RUDDER ON A TWENTY-FOOT MODEL OF A DESTROYER.

Abstract

Eighty tests of the action of a ship rudder were made using a 1/21 scale model of a destroyer. The tests were made in a variable atmosphere towing tank. Motion picture photography was used to observe ventilation and cavitation on the rudder. Some rudder force data were also obtained. These data show a progressive decrease in rudder effectiveness as cavitation number is reduced. (Author)
