Ship with electrically-driven rudder-propeller units, includes flow channel between skegs, designed for low resistance and propulsion performance enhancement |
摘要 |
The flow channel between the skegs (2) is wedge-shaped, widening continuously in the downward- and sternward directions, preferably with slight curvature. Sidewalls of the flow channel are least partially plane surfaces, running out into fin-like bridging sections, which include displacement volume for the water. This configuration promotes a channel effect resulting in low ships resistance. It also influences after-flow, with favorable effect on propulsion performance.
