US 8,267,659 B2 · Turbine blade

Abstract

A turbine blade is provided. The turbine blade includes a support structure and a shell which surrounds the support structure and which is connected to and at a distance from the support structure by at least one spacing element. For example the spacing element can be a solder globule in order to form a space through which a cooling medium can flow between the support structure and the shell. A method for the production of a turbine blade having a support structure and a shell which surrounds the support structure and which is connected to and at a distance from the support structure is also provided. The shell is soldered to the support structure in at least at one place of the support structure in order to connect the shell to and at a distance from the support structure.

A turbine blade, comprising:

a support structure:
a plurality of spacing elements;
and
a shell which encases the support structure and is connected to the support structure using the plurality of spacing elements in a spaced-apart manner,
wherein the plurality of spacing elements are used in order to form a space between the support structure and the shell,
wherein the space is exposed to a throughflow of a cooling medium,
wherein the shell is spot-connected to the support structure using the plurality of spacing elements, and
wherein the plurality of spacing elements are arranged in a distributed manner,
wherein each spacing element is formed as a soldering globule which is connected by soldering the spacing element to the support structure and to the shell.
