In a jet engine having a core that sources a first flow of fluid and a component (such as a fan, a pump, and/or a bleed line) that sources a second flow of fluid, and where the first flow of fluid will typically have, at least during ordinary operation, a higher temperature than the second flow of fluid, at least one flow aperture formed by a first passageway to receive at least a portion of the aforementioned second flow of fluid, wherein that first passageway is comprised of at least one material that (by design and intent) deflects as a function of temperature such that a flow of the second flow of fluid through the at least one flow aperture is thereby desirably modulated.

Flow aperture method and apparatus

A gas turbine engine that includes a turbomachinery core operable to produce a core gas flow and that includes a combustor. A first duct is positioned downstream of and in flow communication with the combustor. A component is positioned within the first duct and extends between radially outward and radially inward walls of the first duct. The component that includes a first cooling passageway formed therein. The first cooling passageway extends between an inlet communicating with the first duct and positioned facing towards the turbomachinery core, and an outlet communicating with a pressure sink.

Cooling structure for a turbomachinery component

An attachment assembly for attaching a center structure to an outer structure at least partially circumscribing the center structure, the attachment assembly having a bushing provided within the center structure or the outer structure, the bushing defining a first through passage, a bushing adapter slidably mounted within the first through passage and defining a second through passage, a threaded passage provided on the other of the center structure or the outer structure and a bolt passing through the first through passage and the second through passage and threaded into the threaded passage.
