  • Publication number: 20220128001
    Abstract: A gas turbine engine comprising at least one radially extending bleed passage in fluid communication with at least one generally circumferentially extending plenum. A plenum has an upstream end in fluid communication with a bleed passage and an outlet for releasing air from the plenum. A plenum further comprises a downstream surface defining a downstream closed end of the plenum and the downstream surface of one or more plenum is/are provided with an outwardly extending projection extending into the plenum.

  • Patent number: 11230943
    Abstract: A turbine rear structure for a gas turbine engine includes a central hub and a circumferential outer ring coaxial with the central hub. The turbine rear structure further includes a plurality of guide vanes extending radially between the central hub and the circumferential outer ring, and an intermediate guide vane located in a space defined between adjacent guide vanes. The intermediate guide vane is located closer to one of the guide vanes than the other guide vane.

  • Patent number: 8998583
    Abstract: A gas turbine engine component providing a gas flow passage is provided, which gas flow passage surrounds an inner passage surface, an outer passage surface forming an outer delimitation of said gas flow passage. In an aspect, the trace of the inner passage surface in a cross-section perpendicular to a central axis of the component presents at least one substantially straight portion. In another aspect, where a plurality of circumferentially spaced blades extends between the inner and outer passage surfaces, two portions of the trace, in a cross-section perpendicular to a central axis of the component, of the outer passage surface between two adjacent blades are substantially straight and oriented in an angle in relation to each other so as to form a concavity in the gas flow passage.

  • Patent number: 5806735
    Abstract: A load carrier for a vehicle has a load carrier bar which, at opposite ends, has anchorage devices for fixing on longitudinal so-called railings on the vehicle root. The anchorage devices have two clamping jaws (14) which, from opposite sides, are urgable against the railings. The one clamping jaw (14) has a sliding body (20) which is disposed in a channel (6) in the load carrier bar and has a free-going aperture (25) for a screw (21). The other clamping jaw (14) has a wedge body (17) slidable in the channel and provided with a through aperture (25) for the screw (21). The wedge body (17) of the clamping jaw (14) cooperates in the channel (6) with a second wedge body (19) which has a threaded aperture (26) for the screw. By tightening the screw (21), the wedge bodies (17, 19) are tightened towards one another and positionally fixed in the channel (6) at the same time as the clamping jaws (14) are forced towards one another.
