A method for abrasive flow machining includes moving an abrasive media through a high-aspect passage of a workpiece. Local pressure of the abrasive media is increased at target abrasion surfaces of the high-aspect passage using a passage geometry that is configured to direct flow of the abrasive media into the target abrasion surfaces such that the target abrasion surfaces are preferentially polished by the abrasive media over other, non-targeted surfaces of the high-aspect passage at which the flow of the abrasive media is not directed into.

An additively manufactured component with an internal passage; and a multiple of ultrasonic horns additively manufactured within the internal passage. A method of removing conglomerated powder from an internal passage of an additively manufacturing a component, including ultrasonically exciting at least one of a multiple of the ultrasonic horns within an internal passage of an additively manufactured component

Additive manufactured conglomerated powder removal from internal passages with co-built ultrasonic horns

An additive manufacturing process includes simultaneously constructing a component and a non-contacting thermal support for the component. The non-contacting thermal support includes a three dimensional negative of the component. The non-contacting thermal support transfers heat from the component into a heat sink.

A method of forming a component using electro-chemical machining includes the steps of providing a shield in a current distribution path between a workpiece and an electrode, with the shield concentrating current distribution upon an end of the workpiece.

Method for creating airfoil leading and trailing edges

Abrasive flow machining method

A finishing apparatus including a central control machine having a computerized controller, at least one articulating device controlled by the central control machine and operable to move the machining tool, and at least one of a touch sensor apparatus and a visual sensor apparatus mounted to said machining tool and communicatively coupled to the computerized controller. The computerized controller configured to cause the finishing apparatus to position a machining element in contact with an exterior surface of a film cooled article, move the machining element along the exterior surface while maintaining contact between the machining element and the surface, identify an actual position of a film opening based on sensory feedback while maintaining contact between the machining element and the surface, and remove material from the exterior surface at the film opening using said machining element.

Apparatus for creating a film cooled article for a gas turbine engine

A method for manufacturing a gas turbine engine component from a molybdenum-rich alloy. The method includes the steps of providing a molybdenum powder of at least 50% molybdenum by weight, extruding the molybdenum powder to provide a first shape, forming the first shape to a second shape and forging the second shape to provide a third shape.
