Title: Ship's rudder has a rudder shaft through the hollow rudder column with a structured configuration to give a common rudder surface center of gravity
Inventor: DUDSZUS ALFRED
IPC: B63H25/38
Filed: 1998-09-10
Abstract: The ship's rudder has a rudder shaft (5) through a hollow reinforced rudder column (1) without finger stall bearing mountings. A fixed guide head (2) is in the zone between the ship's hull and up to half the height of the upper propeller flow stream to form a strengthening bond. The hollow rudder column (1) is strengthened from a point before it emerges from the stern to the lower rudder shaft bearing (7). The hollow rudder column (1) brings the lower and pref. trapezoid rudder surface (10) wholly or mostly in the propeller flow stream. The upper surface (11) of the rudder is behind the hollow rudder column (1) and fixed guide head (2), and forms a common surface center of gravity (12) to reduce the bending forces near the cone coupling (8) and lower shaft bearing mounting (7).
