Abstract: An assembly includes a case structure, a seal interfacing with the case structure, a first pin, and a main pin hole on one of the seal and the case structure. The first pin extends through the main pin hole and is fixed relative to the other of the seal and the case structure. The assembly also includes a second pin and a secondary pin hole on one of the seal and the case structure. The second pin extends through the secondary pin hole. A cross-sectional gap area between the second pin and the secondary pin hole is greater than a cross-sectional gap area between the first pin and the main pin hole. Also included is a bolt hole on one of the seal and the case structure. The bolt hole is circumferentially located between the main pin hole and the secondary pin hole.

Abstract: A combustor panel may comprise a panel wall comprising a proximal surface and a distal surface. A standoff may be formed over the distal surface of the panel wall. An aperture may be formed through the standoff and may extend from a face of the standoff to the proximal surface of the panel wall. The face of the first standoff may be oriented at an angle between 90 degrees and 160 degrees relative to a plane parallel to the distal surface of the panel wall.

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.
