摘要： A gas turbine engine comprises a main gas path having an inner flow boundary wall and an outer flow boundary wall. A turbine exhaust case inner body defines a portion of the inner flow boundary wall of the main gas path. A lobed exhaust mixer defines a portion of the outer flow boundary wall of the main gas path. A stiffener ring is interconnected to at least a number lobes of the lobed exhaust mixer by a plurality of circumferentially spaced-apart struts extending through the main gas path. The stiffener ring is attached to the turbine exhaust case inner body by flexible features, such as circumferentially spaced-apart spring blades.

摘要： An exhaust duct for a gas turbine engine has an annular inlet conduit having an inlet axis. At least two outlet conduits branch off from the inlet conduit along respective outlet centerlines that are distinct from one another. The outlet centerlines when projected onto a projection plane perpendicular to the inlet axis are spaced apart from the inlet axis so as not to intersect the inlet axis.

摘要： A condenser includes a plurality of heat transfer pipe groups, a main body and an intermediate body. The intermediate body has an intermediate body inlet that opens from the inside in a horizontal direction, and an intermediate body outlet that opens downward from the inside. The main body has a main body inlet that opens upward from the inside and is connected to the intermediate body outlet. The plurality of heat transfer pipe groups are arranged in the horizontal direction and disposed in the main body. A near-side outlet edge that is an edge of the intermediate body outlet on a side near the intermediate body inlet in the horizontal direction is disposed below the uppermost position among the plurality of heat transfer pipe groups.

摘要： A sound attenuation apparatus includes a body and a stacked cavity structure. The structure includes a structure inlet formed in the top surface of the body; a passage extending from the structure inlet into the interior of the body to a base surface within the body; a first cavity with a first cavity inlet fluidly coupled to the passage and being formed by a first arm, a first side wall within the interior of the body, and the base surface; and a second cavity with a second cavity inlet fluidly coupled to the passage and being formed by a second arm, the first side wall, and the first arm. Each of the first and second arms extends from the first side wall and includes at least two arm segments oriented at different angles relative to the first side wall longitudinal axis.

摘要： A turbine diffuser configured for use in a turbocharger is disclosed. The turbine diffuser may comprise a diffuser wall defining the diffuser and circumscribing a central axis of the diffuser, and a plurality of deswirl ribs each extending axially along the diffuser wall. Each of the deswirl ribs may have a first end attached to the diffuser wall, and an opposing second end exposed in an interior space of the diffuser. The deswirl ribs may be configured to reduce rotation of exhaust gas that flows through the diffuser.

摘要： An exhaust frame includes: an inner casing; an inner diffuser which defines, between the inner diffuser and the inner casing, an annular inner cooling passage connected to a final-stage wheel space; an outer diffuser which defines an exhaust passage between the outer diffuser and the inner diffuser; an outer casing which defines an annular outer cooling passage between the outer casing and the outer diffuser; a strut which connects the inner casing and the outer casing to each other while crossing the exhaust passage; a strut cover which connects the inner diffuser and the outer diffuser to each other, and defines, between the strut cover and the strut, an annular connection passage connecting the inner cooling passage and the outer cooling passage to each other; and a communication hole provided in a wall of the outer cooling passage at a position on the downstream side of a center line of the strut in the flow direction of a combustion gas.

摘要： A gas turbine engine includes a propulsor with a power turbine, a power turbine shaft extending forward therefrom defining a centerline axis, and a fan driven by the power turbine shaft. The fan is aligned with the centerline axis forward of the power turbine and is operatively connected to be driven by the power turbine through the power turbine shaft. A gas generator operatively connected to the propulsor is included downstream from the fan and forward of the power turbine, wherein the gas generator defines a generator axis offset from the centerline axis. The gas generator is operatively connected to the power turbine to supply combustion products for driving the power turbine.

摘要： An axial flow rotating machine has: a rotor with a plurality of rotor blades; a stator with a plurality of stator blades; an axial flow rotating portion defined by the rotor and the stator; and a diffuser connected to the axial flow rotating portion on a downstream side of the axial flow rotating portion. A final blade portion inner-circumferential inner wall, which is a portion of an inner-circumferential inner wall of the axial flow rotating portion, is defined such that a diameter thereof at a trailing edge position of a final blade is smaller than the diameter at a leading edge position of the final blade. In addition, a diameter of all or a portion of a diffuser inner-circumferential inner wall decreases in a direction of the downstream side in an axial direction.
