    Abstract: A cast plate heat exchanger includes a first surface including a first surface inlet end and a first group of augmentation features defining a first average density of augmentation features across the first surface. A second surface is in heat transfer communication with the first surface. The second surface includes a second surfaces inlet end and a second group of augmentation features defining a second average density of augmentation features across the second surface. A total augmentation feature density ratio is defined from the first average density of augmentation features to the second average density of augmentation features. A first region is shared by both the first surface and the second surface and covers at least a portion of the first surface inlet end. The first region includes a first region augmentation feature density ratio that is less than the total augmentation feature density ratio.

    Abstract: An assembly is provided for rotational equipment with an axial centerline. This assembly includes a primary seal device, a ring structure and a secondary seal device. The primary seal device is configured as a hydrostatic non-contact seal device. The primary seal device includes a plurality of seal shoes and a seal base. The seal shoes are arranged circumferentially about the axial centerline in an annular array. The seal base circumscribes the annular array of the seal shoes. The ring structure is axially engaged with the seal base. The secondary seal device is mounted with the ring structure. The secondary seal device includes a seal ring body and an alignment tab. The seal ring body is configured to substantially seal an annular gap between the ring structure and the seal base. The alignment tab projects out from the seal ring body and into an aperture in the ring structure. The alignment tab is adapted to substantially rotationally locate and/or fix the secondary seal device to the ring structure.

    Abstract: A pre-diffuser and exit guide vane (EGV) system for a gas turbine engine includes an annular EGV assembly containing a number of guide vanes and having an annular opening bounded by a radially inner annular sealing surface at a first radius and a radially outer annular sealing surface at a second radius. First and second seals substantially matching the first and second radii respectively join the EGV assembly to an annular pre-diffuser having an annular opening bounded by radially inner and outer annular sealing surfaces at substantially the first and second radii. The seals seal the inner sealing surface of the EGV assembly to the inner sealing surface of the pre-diffuser and the second seal seals the outer sealing surface of the EGV assembly to the outer sealing surface of the pre-diffuser, such that the EGV assembly annular opening is in fluid communication with the annular opening of the pre-diffuser.

    Abstract: A pre-diffuser of an inner diffuser case of a gas turbine engine may comprise an annular outer wall and an annular inner wall radially inside of the annular outer wall to define a passage for primary airflow therebetween. The pre-diffuser may further comprise at least one strut extending radially between the annular inner wall and the annular outer wall and at least one aperture formed in the strut that extends radially through the strut, the annular inner wall, and the annular outer wall. The pre-diffuser may further comprise at least one hollow cavity formed in the strut, and the hollow cavity may be separate from the aperture.

    Abstract: An outer diffuser case of a diffuser case assembly for use in a gas turbine engine may have a housing orientated about an engine axis, a forward flange projecting radially outward from the housing, a mid-flange spaced axially aft of the forward flange and projecting radially inward from the housing, and an aft flange projecting radially outward from the housing. The mid flange is spaced axially between the forward and aft flanges and is configured to detachably engage an inner diffuser case of the case assembly. The forward flange is configured to detachably engage a high pressure compressor and the aft flange is configured to detachably engage a high pressure turbine of the engine.
