摘要： The seal arrangement is configured to provide an airtight and fluid-tight seal between a first component (102) and a second component (104). The seal arrangement has a first pressure boundary seal (210) disposable at least partially within the gap (116) between the first component and the second component. The first pressure boundary seal is fixable to one of the first (102) or second components (104) to create an airtight seal with the other of the first (102) or second component (104). The seal arrangement has also a first flame deflector (220) that is configured to bridge across and cover the gap between the first component and the second component so as to create a fluid-tight seal over the gap between the first component and the second component. The first flame deflector has a convex external shape so as to prevent any fluid impinging upon the first flame deflector from pooling on the first pressure boundary seal.

摘要： A pressure relief arrangement for a gas turbine engine comprises a panel and a plurality of pressure relief mechanisms provided in the panel. The mechanisms have a first configuration and a second configuration. In the first configuration the panel is sealed to prevent fluid flow through the panel in a thickness direction and in the second configuration the mechanisms are arranged so that a plurality of holes are provided in the panel so fluid can flow through the panel in a thickness direction.

摘要： A method of manufacturing an annular component is provided. The method comprises the steps of providing an annular shell (90) to form the outer wall of the component and a plurality of flat annular rings wherein a radially inner edge of each ring is shaped to correspond to a cross-section of the shell at a different position along its length. The method comprises attaching each ring to the ring(s) adjacent to it at a plurality of circumferentially spaced discrete positions. The method comprises deforming each flat annular ring into a corrugated three-dimensional shape, wherein the corrugations extend out of the flat plane and comprise radially defined peaks and troughs. The method comprises locating the shell (90) within the plurality of attached, deformed annular rings (91-95). The method comprises attaching the plurality of attached, deformed annular rings (91-95) to the shell (90) to form the component, so that the plurality of attached, deformed annular rings (91-95) provide structural reinforcement to the shell (91-95).
