A tilting pad gas bearing includes: a plurality of bearing pads disposed in a circumferential direction of a rotor; and a pivot member that swingably supports the bearing pads. Each of the bearing pads has a curved shape and includes: a pad main body supported by the pivot member; a heat insulating material layer disposed on a side of the pad main body that faces the outer circumferential surface of the rotor, and formed of a material having a thermal conductivity lower than a thermal conductivity of the pad main body; and a concave portion disposed in an outer circumferential surface on an outer circumferential side of the bearing pad in a curving direction. A base end of the pivot member is fixed to a housing, and the pivot member has a protruding portion that passes through the housing.

A component for a gas turbine engine is disclosed. In various embodiments, the component includes a diffuser ring, a combustor and a spring element connecting the diffuser ring to the combustor.

A gas turbine engine includes a rotor that has a rotor disk and a plurality of circumferentially-spaced blades. The rotor disk and the blades are co-rotatable about an axis. A case circumscribes the rotor. The rotor disk is tuned, with regard to centrifugal and thermal growth responsiveness, to the case for a given operational scenario of the gas turbine engine such that the rotor disk and case together provide a tuned clearance response. The operational scenario involves a series of engine events that include at least two of engine acceleration, engine deceleration, engine steady-state operation.

A balance piston seal assembly for a balance piston of a compressor is provided. The balance piston seal assembly may include a balance piston seal configured to be disposed about the balance piston such that an inner radial surface of the balance piston seal and an outer radial surface of the balance piston define a radial clearance therebetween. The balance piston seal assembly may also include a plurality of heaters in thermal communication with the balance piston seal and configured to heat and thermally expand the balance piston seal and thereby increase a radial length of the radial clearance.

A method for manufacturing a panel includes disposing one or several supports in a respective cavity(ies) in a honeycomb structure having a first skin and a second skin clasping the honeycomb structure. The supports are made of a fugitive material such as a thermoplastic and are auxetic so that, under the effect of an increase in temperature, their dimension between the first and the second skins remains below a predetermined value.

A low profile embedded BTC probe may comprise a housing having a cavity disposed radially outward of a blade, a lower insulator disposed within the cavity, a sensor element disposed within the cavity, an upper insulator disposed within the cavity, a cap wherein the cap fills a remainder of the cavity, and a hard lead in electronic communication with the sensor element and the housing.

The invention is directed to a seal arrangement, in particular a brush seal, for a turbine, in particular an aircraft gas turbine, with a sealing element and with a sealing surface that interacts with the sealing element, wherein the sealing element and the sealing surface are arranged concentrically with respect to each other, in particular concentrically around a machine axis of the turbine is hereby characterized in that the sealing element and the sealing surface are designed in such a way that, in a first operating state, a gap is formed between them, and in that, in a second operating state, a sealing contact is produced between the sealing element and the sealing surface.

Methods for repairing a thermal barrier coating deposited on a component with localized spallation of the thermal barrier coating includes depositing a primer slurry on a thermally grown oxide of the component exposed by the localized spallation, depositing a ceramic slurry on the primer slurry, and heating the primer slurry and the ceramic slurry. The primer slurry includes a primer that includes at least one of a metal and a metal oxide. The ceramic slurry includes a ceramic material, a ceramic slurry binder material, and a ceramic slurry fluid carrier. Heating the primer slurry and the ceramic slurry forms a first chemical bond between the primer and the thermally grown oxide and a second chemical bond between the primer and the ceramic material.

An apparatus and method of forming a heat exchanger includes forming a monolithic core body having a first set of flow passages and a core coefficient of thermal expansion, and additively manufacturing onto the monolithic core a first manifold defining a first fluid inlet for the first set of flow passages.

A headset, during play of a particular game, receives a plurality of audio channels carrying game sounds and determines whether a first of the game sounds overwhelms a second of the game sounds. In response to the determination, the headset adjusts a level of one or more of the audio channels such that perceptibility of the second game sound is improved relative to perceptibility of the first game sound prior to the adjustment, wherein for the adjustment, a level of one or more of the audio channels carrying the first game sound is decreased while a level of one or more of the audio channels carrying the second game sound is maintained or increased. The audio channels include three or more audio channels and the adjustment of the level of the audio channels is performed while the three or more audio channels are combined into two stereo channels.
