A gas turbine component for a gas turbine is provided. The gas turbine component has a shell portion having an abradable portion () to allow rotor blade ends () of a rotor blade array of the gas turbine to rub into the same. The abradable portion adjoins a neighboring portion () of the shell portion axially at both sides and is additively manufactured together therewith.

Gas turbine component

The segmented seal carrier of a guide vane ring of a turbomachine has a number of segments that form two half-rings of the seal carrier when assembled. They are clamped together by their opposite-lying, corresponding lateral contact regions.

Seal carrier, guide vane ring and turbomachine

A method for manufacturing a turbine casing part having a bearing chamber system including a shell () and at least one bearing receptacle () and further having a protective heat shield () that at least partially encompasses the shell () radially outwardly, the protective heat shield () being additively manufactured integrally with the bearing chamber system by selectively solidifying layer-by-layer a feedstock material () is provided.

Method for additive manufacturing of a gas turbine casing part

The invention relates to a guide vane ring with at least one guide vane ring segment for a turbomachine, including a plurality of guide vanes arranged radially around an axis of rotation, an outer shroud arranged radially on the outer side of the guide vanes, and an inner shroud arranged radially on the inner side of the guide vanes, wherein the outer shroud or the inner shroud has at least one expansion joint, wherein the guide vane ring segment is formed in one piece with the guide vanes, the outer shroud, and the inner shroud and the at least one expansion joint is sealed in each case by at least one sealing device arranged in the respective expansion joint.

A shaft seal system which is disposed axially between a first chamber and a second chamber is disclosed. The shaft seal system includes a shaft, a casing that surrounds the shaft, and a seal which is disposed axially closer to the second chamber where the first chamber has a fluid and the second chamber is to be protected from the fluid. In this arrangement, the seal includes a pressure booster.

Shaft seal system and a compressor having a corresponding shaft seal system

A turbine engine and a rotor for a turbine engine are provided. Several adjacent turbine blades are positioned in the circumferential direction of the rotor, each turbine blade having a blade root, each turbine being fixed in a retainer groove, running in the circumferential direction of the rotor, by means of the blade root. Each turbine blade may be introduced, by the blade roots thereof, into the retaining groove, by means of a filling groove, whereby the width of the filling groove is matched is matched to the width of the blade roots. The width of the blade roots () and the width of the, or each filling groove () in the circumferential direction is greater than half the width of a desired nominal blade pitch (), whereby in the region of the, or each filling groove (), a first number of turbine blades () with desired nominal blade pitch (), is exchanged for a second number of turbine blades (), with increased blade pitch (), the first number being greater than the second number.

Turbine engine and bladed rotor for a compression stage of a turbine engine

A nozzle ring for a gas turbine, more particularly for an aircraft engine, has at least one shroud with a circumferential surface and at least one blade with a surface. The shroud has at least one opening for fastening the blade. The blade has at least one end section with a platform which projects at least partially over its circumference and which has a transition curve and which is inserted into the opening.
