Abstract
In order to provide a rudder blade, which has a low level of weight, is easier and more inexpensive to manufacture, that meets the various strength and stability requirements for various rudder-blade sections, which can be at least partly manufactured in an automated manner and for which the manufacturing of irregular surfaces, in particular, the leading edge, is made easier, a rudder blade is proposed, which has a modular structure, wherein the rudder blade comprises at least two prefabricated rudder-blade segments and is composed of the at least two prefabricated rudder-blade segments.
Claims15
A rudder blade having a modular structure, wherein the rudder blade comprises at least two prefabricated rudder-blade segments and is composed of the at least two prefabricated rudder-blade segments.
(canceled)
A segment for a rudder blade or for an apparatus for improving propulsion, in particular, a rudder-blade segment or a nozzle segment, wherein the segment is manufactured by means of a generative manufacturing method and/or an additive manufacturing method, in particular, a 3D-printing method, wherein the segment preferably comprises a leading edge.
A method for manufacturing a rudder blade with modular constructions, comprising the steps:
- manufacturing a first rudder-blade segment,
- manufacturing a second rudder-blade segment,
- joining at least the first rudder-blade segment and the second rudder-blade segment.
