Rudder aspect ratio

Webb6 aug. 2024 · Aspect Ratio = (Depth of Rudder / Width of Rudder) The force on the rudder depend on: 1. Area of the rudder. 2. The form of rudder. 3. The speed of the ship. 4. The angle of helm. Force acting on the rudder, F = k A V². where, k = Constant depending upon the shape of the rudder, water density, rudder angle. It varies from 570 to 610. A = Area ... WebbBeyond this, it is of particular interest the effect that steering elements have on two aspects; the effect upon propulsive factors and the manoeuvrability capability. In the present paper a study of the effects upon propulsive factors and the manoeuvrability by different rudder configurations and shapes have been carried out.
