Abstract: A blade outer air seal for a turbomachine includes a base portion configured to attach to a turbomachine housing, a thermal coating disposed on the base portion, and at least one groove defined in an external surface of the thermal coating. The groove can be machined. A method of manufacturing a blade outer air seal includes disposing a thermal coating on a base portion, and machining at least one groove into the thermal coating. The method can also include using an automated force sensing and vision sensing equipped robotic system.

Abstract: The present disclosure provides an assembly for a gas turbine engine. The assembly may comprise a tierod, a bearing mounting ring, and a joint coupling the tierod to the bearing mounting ring. The joint may be configured to increase a volume of a bearing compartment on an inner surface of the bearing mounting ring. A coefficient of thermal expansion of the bearing mounting ring may be substantially the same as the coefficient of thermal expansion of the tierod.

Abstract: A staged high temperature heat exchanger (HEX) may comprise a first stage made from a first material and a second stage made from a second material. The first stage may comprise an inlet manifold configured to receive a flow of fluid. The second stage may comprise an outlet manifold whereby the flow of fluid exits the HEX. The first stage is configured to withstand the temperature of the flow of fluid entering the inlet manifold and configured to reduce the temperature of the flow of fluid to an intermediate temperature before the flow of fluid reaches the second stage. In various embodiments, the first material may comprise a nickel-based superalloy having at least 40% of a Ni3(Al,X) precipitate phase, X being a metallic or refractory element other than Al.
