METHOD FOR CREATING A BLADE FOR A FLOW ENGINE AND BLADE FOR A FLOW FORCE ENGINE

摘要

A method for creating a blade (11) for a turbo-engine and such a blade are disclosed. Components (19) of the blade are produced by an additive production method such as selective laser melting or fusion, while a main body (18) is produced by casting, for example. The blade components (19) may consist of a different material than the basic body (18). The components or body may carry functions such as serving as drainage slots (24). Expense related to the use of additive production methods occurs only for the components (19) in which a complicated geometry, for example, must be implemented. The remaining components in the form of the main body (18), comprising the blade (27), the blade foot (28) and the blade head (29), can be cost-effectively implemented as a cast part or a sheet metal part.

主权项

1. A method for making a blade for a turbo-engine comprising the steps of:
providing a basic body of the blade and connecting the basic body permanently to at least one blade component for completing the basic body with the component to form the finished blade, by producing the at least one blade component directly on the basic body by an additive manufacturing method; and further comprising the connecting comprising producing of the blade component comprising producing a plurality of completing blade components, which butt directly one against the other and together define a completing structure for the basic body.
