ASYMMETRIC CURRENT-FIXED VANE

摘要

PURPOSE: An asymmetric current-fixed vane is provided to cut down expenses by improving efficiency and reducing the weight. CONSTITUTION: In a current-fixed vane installed in front of a propeller of the stern, a current-fixed vane is asymmetrically installed at the port side and the starboard side. In the current-fixed vane, three current-fixed vanes are installed at the port side each at an angle of 45 degrees and two current-fixed vanes are installed at the starboard side each at an angle of 60 degrees. The code length of the current-fixed vanes of the starboard side is 80% of the code length of the current-fixed vanes of the port side. The angles of the current-fixed vanes of the port side to the axial central line are 12 degrees, 6 degrees, and 10 degrees, and the angles of the current-fixed vanes of the starboard side to the axial central line are 12 degrees and 18 degrees.
