More Information
Summary:Each blade 1 has perforations 2 on the lee side thereof and is connected via a passage 4 through the hub 3 with the thrust side of the propellor. This arrangement, which during rotation of the propellor causes water to flow from the thrust side of the propellor via the passage in the hub to the hollow space in the corresponding blade and thence via the perforations to the region at the lee side of the propellor, has been found to improve the propellor's efficiency in operation in a ship's propulsion mechanism.
