Systems and methods for thermal seals are described herein. A thermal seal may comprise a first metallic plate having a first inner surface and a first outer surface, a second metallic plate having a second inner surface and a second outer surface, the second metallic plate being oriented substantially parallel to the first metallic plate such that the first inner surface and the second inner surface are separated by a gap, and a thermal wool having a plate portion in contact with the first inner surface and the second inner surface, the plate portion filling a void between the first inner surface and the second inner surface, and having a shoulder portion extending from a perimeter of the plate portion, the shoulder portion extending outward from between the first metallic plate and the second metallic plate.

The present disclosure generally relates to methods for additive manufacturing (AM) that utilize integrated ribs to support thin walled annular structures. An annular wall fabricated using AM has a thickness less than 0.022 inches across a majority of a surface of the annular wall and a plurality of ribs having a thickness greater than 0.030 inches. The annular wall has a mean thickness less than 0.100 inches. The annular wall conforms to a surface of the component and a mean distance between the annular wall and the component is less than 0.080 inches.

A mounting bracket for mounting an accessory to a gas turbine engine comprises a space frame structure. The space frame structure comprises a plurality of struts joined to one another at nodes.

A mobile machine tool for segmentally machining, in situ, a component, in particular a component of a turbine, which is rotatable about an axis of rotation. The machine tool has a main body, a support element which is held on the main body so as to be movable about a C-axis along a circular-arc-shaped guide path, and a tool module which is held on the support element and is designed to receive a tool. The tool module is located on the support element so as to be linearly movable. A method segmentally machines, in-situ, a component which is mounted in a stationary body so as to be rotatable about an axis of rotation.

A centering device (10) for centering a turbine housing (40) with respect to a central axis (33) of a radial turbine of a turbo system is described. The centering device (10) includes a ring-shaped body (11) having an outer diameter D1 and an inner diameter D2, wherein a ratio of D1/D2 is ≤2.
