Abstract: A method of cooling a portion of a gas turbine engine includes positioning a tie rod relative to an inner frame case. The tie rod includes a bushing opening and the inner frame case includes a fastener opening. A fastener is secured through the fastener opening in the inner frame case to a threaded bushing located in the bushing opening. The threaded bushing includes a distal end that forms a clearance gap with the inner frame case. Heat is transferred from the fastener through the threaded bushing to prevent the fastener from creeping.

Abstract: An inner case for a gas turbine engine includes a case body defining a centerline axis. The case body includes a turbine seal support, and an I-rod support downstream of the turbine seal support. A mid-turbine frame for a gas turbine engine includes an inner case having an integral case body. A method for manufacturing an inner case for a turbomachine with an integral high pressure turbine seal support includes fabricating a case body.

Abstract: A cooling structure for a gas turbine engine comprises a gas turbine engine structure defining a cooling cavity. A cooling component is configured to direct cooling flow in a desired direction into the cooling cavity. A bracket supports the cooling component and has an attachment interface to fix the bracket to the gas turbine engine structure. A first orientation feature associated with the bracket. A second orientation feature is associated with the gas turbine engine structure. The first and second orientation features cooperate with each other to ensure that the cooling component is only installed in one orientation relative to the gas turbine engine structure. A gas turbine engine and a method of installing a cooling structure are also disclosed.

Abstract: A gas turbine engine component has an engine case structure surrounding an engine center axis. A plurality of holes are formed in the engine case structure, wherein the holes are circumferentially spaced apart from each other about the engine center axis. The plurality of holes includes at least one balance hole and at least one service hole that is configured to allow another engine component to pass through the at least one service hole. At least one cover is configured to cover at least one balance hole such that air is prevented from passing through the at least one balance hole.
