Abstract
Methods for manufacturing a tandem guide vane segment that includes an outer platform, a front guide vane, and a rear guide vane, wherein the front guide vane and the rear guide vane are arranged in a firmly fixated manner with respect to one another. One method includes manufacturing an integral front segment section that includes the front guide vane and a front section of the outer platform, manufacturing an integral rear segment section that includes the rear guide vane and a rear section of the outer platform, and connecting the two segment sections to each other.

A method for manufacturing a tandem guide vane segment that comprises an outer platform, a front guide vane, and a rear guide vane, wherein the front guide vane and the rear guide vane are arranged in a firmly fixated manner with respect to one another and form a gap in between them, wherein the method comprises:
- manufacturing an integral intermediate structure that has material areas that comprise the final outer platform, the final front guide vane, and the final rear guide vane, wherein, in the intermediate structure, the gap between the final front guide vane and the final rear guide vane is filled with material of the intermediate structure,
- further processing of the intermediate structure into the final tandem guide vane segment, wherein the further processing comprises manufacturing a gap in the intermediate structure for separating the front and the rear guide vane.
A method for manufacturing a tandem guide vane segment that comprises an outer platform, a front guide vane, and a rear guide vane, wherein the front guide vane and the rear guide vane are arranged in a firmly fixated manner with respect to one another, and overlap each other in the axial direction, wherein the method comprises:
- manufacturing an integral front segment section that comprises the front guide vane and a front section of the outer platform,
- manufacturing an integral rear segment section that comprises the rear guide vane and a rear section of the outer platform, and
- connecting the two segment sections.
A method for manufacturing a tandem guide vane segment that comprises as components an outer platform, a front guide vane, and a rear guide vane, wherein the front guide vane and the rear guide vane are arranged in a firmly fixated manner with respect to one another, wherein the method comprises:
- manufacturing at least one of the guide vanes as a separate structural component, and
- connecting the guide vane manufactured as a separate structural component to at least one of the other structural components.
A method for manufacturing a tandem guide vane segment that comprises an outer platform, an inner platform, a front guide vane, and a rear guide vane, wherein the front guide vane and the rear guide vane are arranged in a firmly fixated manner with respect to one another, wherein the method comprises:
- manufacturing the outer platform and one of the guide vanes as a first integral structural component;
- manufacturing the inner platform and the other guide vane as a second integral structural component;
- and
- connecting the two integral structural components by connecting the radially outer vane end of the other guide vane to the outer platform, and the radially inner vane end of the one guide vane to the inner platform.
