Abstract: A seal arrangement configured to provide an airtight and fluid-tight seal between a first component and a second component, having a first pressure boundary seal disposable at least partially within the gap between the first component and the second component, the first pressure boundary seal being fixable to one of the first or second components to create an airtight seal with the other of the first or second component, the seal arrangement also having a first flame deflector 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, where 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.

Abstract: A bracket for mounting a first component to a second component, the bracket comprising at least one mounting boss defining a through-hole having an opening axis in axial direction for receiving a fixing used to attach the bracket to one of the first and second components; wherein the mounting boss comprises a fixing support face around the through-hole on a surface of the bracket, the fixing support face configured to bear a head of the fixing; the mounting boss is configured to resist compressive forces exerted on the bracket by the head of the fixing; and the mounting boss comprises a cavity in a space projected from the fixing support face in the axial direction of the through-hole.

Abstract: 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.
