Abstract: A combustor for a gas turbine engine includes a liner having a first surface, a second surface opposite the first surface, and defining a plurality of effusion cooling holes. At least one of the effusion cooling holes includes an inlet section and a converging section downstream of the inlet section. The at least one of the effusion cooling holes includes a metering section downstream of the converging section. The at least one of the effusion cooling holes includes an outlet section downstream of the metering section. The outlet section is proximate to the second surface. The inlet section, the converging section, the metering section and the outlet section extend along a longitudinal axis, with the inlet section asymmetrical relative to the longitudinal axis and the metering section symmetrical relative to the longitudinal axis.

Abstract: A multi-channel particle separator includes a plurality of vanes. Each vane is spaced apart from at least one other adjacent vane to define a flow channel, and includes a leading edge, a trailing edge, a first side wall, a second sidewall, and a splitter. The first side wall extends between the leading edge and the trailing edge. The second side wall is spaced apart from the first side wall and extends from the leading edge toward the trailing edge. The splitter may be rotationally coupled to the trailing edge and extend toward the leading edge. The splitter is spaced apart from the first side wall to define a scavenge volume and is rotatable between an extended position and a retracted position. The vanes may also or instead be coupled to a ring-shaped structure.

Abstract: A combustor for a gas turbine engine includes a first liner having a first surface, a second surface opposite the first surface, and a wall having a thickness defined between the first surface and the second surface. The first liner defines a plurality of effusion cooling holes, and at least one of the effusion cooling holes includes an inlet section spaced apart from the first surface, and a converging section downstream of the inlet section. The inlet section and the converging section are each defined so as to be outside of the thickness. The at least one of the effusion cooling holes includes a metering section downstream of the converging section and a portion of the metering section is defined within the thickness. The at least one of the effusion cooling holes includes an outlet section downstream of the metering section. The outlet section is proximate to the second surface.

Abstract: A low-leakage seal assembly for a turbomachine's combustor-turbine interface. A turbomachine includes a combustion chamber that receives compressed air for combustion from a compressor. The combustion chamber is defined by a combustion liner terminating in a seal ring where the seal ring has an enlarged head that is thicker than the remainder of the seal ring. A transition liner directs combustion gases from the combustion chamber to the turbine and has three walls forming a cavity with an open end. The seal ring extends through the open end and the head nests in the cavity. The transition liner and the seal ring are parts of a low-leakage seal assembly that is exposed on one side to the compressed air and that is exposed on another side to the combustion gases.

Abstract: An inlet particle separator system includes a shroud section and a hub section that is at least partly surrounded by the shroud section. The hub section is spaced apart from the shroud section. The inlet particle separator system also includes a flow passageway with an air inlet defined between the hub section and the shroud section. The flow passageway branches downstream of the air inlet into a main passage and a pre-cleaner passage. The main passage is defined between the hub section and the shroud section. The pre-cleaner passage includes a pre-cleaner inlet and extends at least partially through the hub section. Furthermore, the system includes a splitter that divides the main passage into scavenge and engine flow paths. The pre-cleaner inlet is partly defined by a first surface of the hub section. The first surface faces substantially in an upstream direction toward the air inlet.

Abstract: A turbine nozzle assembly includes an inner circumferential support platform, an outer circumferential support platform, and a plurality of airfoil vanes disposed between the inner circumferential support platform and the outer circumferential support platform. The turbine nozzle assembly further includes a plurality of impingement plates disposed along a radially outer surface of the outer circumferential support platform or a radially inner surface of the inner circumferential support platform, and a plurality of gap-maintaining features disposed between the plurality of outer or inner circumferential support platforms and the plurality of impingement plates. Each gap-maintaining feature of the plurality of gap-maintaining features is provided at a height such that a cooling air flow space is maintained between the plurality of outer or inner circumferential support platforms and the plurality of impingement plates.

Abstract: An inlet particle separator system for a vehicle engine includes a hub section, a shroud section, and a splitter. The hub section has a hub outer surface that diverges, relative to the axis of symmetry, to a hub apex. The shroud section has a shroud inner surface that surrounds, and is spaced apart from, at least a portion of the hub section to define a main flow passageway between the hub outer surface and the shroud inner surface. The splitter is disposed downstream of the air inlet and extends into the main flow passageway to divide the main flow passageway into a scavenge flow path and an engine flow path. The hub section and the shroud section are configured such that the cross sectional flow area of the main flow passageway decreases downstream of the air inlet to define a throat section that is disposed upstream of the hub apex.
