Abstract: A gas turbine engine includes a hydrogen fuel delivery assembly configured to deliver a hydrogen fuel flow, a compressor section configured to compress air flowing therethrough to provide a compressed air flow, and a combustor including a combustion chamber having a burner length and a burner dome height. The combustion chamber is configured to combust a mixture of the hydrogen fuel flow and the compressed air flow. The combustion chamber can be characterized by a combustor size rating between one inch and seven inches. In more detail, the combustion chamber can be characterized by the combustor size rating between one inch and seven inches at a core air flow parameter between two and one half kN and sixty kN, in which the combustor size rating is a function of the core air flow parameter.

Abstract: A method for making a ceramic matrix composite component includes densifying a fibrous preform of the component with a ceramic matrix to form an intermediate component; infiltrating a hole in the intermediate component with an infiltrate material comprising a solid and a metallic alloy whose reaction forms a carbide, silicide, boride or combination thereof, heating the infiltrate material to a temperature in excess of a melting point of the metallic alloy; and sequentially cooling regions of the hole starting from an interior end of the hole to the outer surface of the intermediate component to form a solidified through-thickness reinforcement element. The hole extends in a through-thickness direction and is open to an exterior surface of the intermediate component.

Abstract: A combustion section of a gas turbine includes an annular combustion chamber, a burner arrangement upstream of the combustion chamber, an annular compressor diffusor, and an annular combustion casing. The combustion casing has an outer section wall, an upstream section wall, and an inner section wall. The inner section wall extends along the rotor axis and is arranged between the burner arrangement and the compressor diffusor. A shielding is attached to the inner section wall at the side facing the rotor axis with a free space in-between at least. An outer diffusor wall of the compressor diffusor extends in axial direction up to the upstream half of the shielding.

Abstract: A double wall for an aircraft gas turbine combustion chamber comprising an internal wall which is configured to be in contact with the combustion reaction, and an external wall which is at a distance from the internal wall, comprising a plurality of openings so as to allow the circulation of cooling air streams, outside the external wall, which cool the internal wall. The internal wall being free of perforations to prevent any circulation of a cooling air stream towards the centre of the combustion chamber. The the internal wall comprises a plurality of members projecting towards the external wall, each projecting member comprising a foot portion and a cylindrical head portion with a circular cross-section, the head portion extending into an opening with a circular cross-section so as to define a calibrated cross-sectional area between the projecting member and the opening, through which area a cooling air stream can flow.

Abstract: A combustor includes a liner defining a combustion chamber and receiving a fuel and air mixing body. The mixing body has a central fuel supply, and radial distribution passages communicating fuel from the central fuel supply radially outwardly relative to a central axis of the central fuel supply and to mixing passages. The radial distribution passages have injection ports in the mixing passages. The mixing passages extend from a rear face of the mixing body to an inner face facing into the combustion chamber. Air inlets in the mixing body communicate air into the mixing passages, and there is cellular material in the mixing passages at a location at which the fuel is injected into the mixing passages. A gas turbine engine is also disclosed.

Abstract: A combustor for a gas turbine engine includes a head end section containing a fuel nozzle assembly and a liner extending downstream from the head end section to an aft frame and defining a combustion chamber therein. First injectors, disposed at a first axial location, directs a first fuel/air mixture through the liner. Second injectors, disposed at a second downstream axial location, direct a second fuel/air mixture through the liner. A compressor discharge casing, which at least partially surrounds the combustor, defines a plenum from which a first air supply is directed only to the first injectors, a second air supply is directed only to the second injectors, and a third air supply is directed only to the head end section. The second air supply is greater than each of the first air supply and the third air supply.
