Abstract: Quality control method and control system for a stock of a base material for the additive manufacture of components includes selecting a batch of a base material out of a plurality of indexed batches of the stock, wherein base material assigned to the same batch index is indicative to the quality of the respective base material, loading a quantity of base material of the selected batch into a manufacturing system, additively manufacturing the component from the base material, wherein the base material of the selected batch is exposed to manufacturing conditions in a build area and updating the batch index of the base material remaining from the additive manufacture in the build area according to the exposure.

Abstract: A method of additive manufacturing includes additively manufacturing a first section for a component, wherein the first section is provided with a position feature, additively manufacturing a second section for the component on the first section, and, in case that a build failure occurs during the additive manufacture of the second section, machining back a present buildup until the position feature is revealed, additively manufacturing the second section separately from the first section, thereby providing the second section with a corresponding position feature, and connecting the first section and the second section to provide the component.

Abstract: A burner tip for installation in a burner, wherein the burner tip has a surface facing a combustion chamber, an air channel structure leading to the surface and defining an air channel, and a fuel channel structure leading to the surface, and wherein the fuel channel structure defines a fuel channel, which extends in a surface region of the burner tip in a first direction parallel to the surface and then extends back, at least in part, in a second direction, different from the first direction, in order to cool the surface region of the burner tip by a fuel flowing through the fuel channel during operation of the burner tip.

Abstract: A burner tip for fitting in a burner comprising: an air duct system; a fuel channel system open to a surrounding area; and a central air duct of the air duct system running through the burner tip surrounded by a wall structure. The wall structure comprises open pores and/or a space grid. Open pores in the wall structure and/or gaps in the grid form a connection between the central air duct and the surrounding area of the burner tip.

Abstract: Various embodiments include a burner tip for installing in a burner comprising: an air passage system open to the surrounding area of the burner tip; a fuel passage system open to the surrounding area of the burner tip; an inner wall and an outer wall; an annulus between the inner wall and the outer wall; and heat-conducting structures projecting into the annulus from the outer wall connecting the outer wall and the inner wall. The annulus forms a part of the air passage system. The heat-conducting structures include connecting ribs. Connecting passages extend through the connecting ribs, open on one end into the annulus and on another end through the outer wall.

Abstract: A turbine blade for a turbomachine, having a blade airfoil with a blade tip region and a sealing region which has an auxetic material and is arranged and designed such that, when transitioning from a rest state to an operating state of the turbine blade, the blade tip region of the turbine blade expands in a first direction perpendicular to a longitudinal axis of the blade airfoil. An auxetic material is used for a turbine blade for sealing a gas path during operation of a turbomachine.
