Abstract

The invention relates to a blade component for a propeller. The blade component comprises a base which is attachable to a portion of a propeller hub to at least partially enclose the hub and form at least one open ended passage in the hub to permit flow there through. At least one propeller blade extends substantially radially outwardly from the base, and the at least one blade includes a blade face, a blade back, a leading edge, a trailing edge, and a root section connected to the base. An inlet opening is configured on the base which permits flow from the outside to the inside of the enclosed hub. The base or the hub further include a compartment which sub-divides the open ended passage and forms a further water flow passage when the base is attached to the hub, wherein the operatively forward end of the compartment is closed, and the opposing end is open such that water enters the water flow passage through the inlet opening and is directed to flow there through and exit the rear end of the enclosed hub. The inlet opening is configured to run substantially parallel to the axis of the hub, and the inlet opening is further located in register with the water flow passage there below and substantially adjacent to one side of the compartment.
