Abstract
A system for designing and assembling a ships rudder that allows for the manufacture of the rudder components, namely a rudder stock and rudder blade independently, and assembling them into a completed rudder using retaining bolts and injecting an epoxy like cement or grout in order achieve the required strength characteristics.
Claims13
A marine rudder assembly comprising:
- a rudder blade forming an internal central cavity elongated along a vertical axis of the rudder blade, the internal central cavity forming an inside surface along the vertical axis;
- a rudder stock having an upper shaft portion and a lower insert portion, the lower insert portion forming a flattened and twisted configuration extending along the vertical axis such that the lower insert portion of the rudder stock is shaped to fit into and closely conform with a twisted contour formed in the inside surface of the internal central cavity;
- and
- an injectable filler material placed in a gap defined between the inside surface of the internal central cavity and the lower insert portion of the rudder stock.
