  • Patent number: 9546563
    Abstract: Various methods and systems are provided for an axial turbine including a containment shroud. In one example, an axial turbine for use in an engine system comprises a turbine disc/blisk and a shroud housing the turbine disc/blisk, the shroud including a first region, a second region, and a third region. A thickness of the second region is dependent on a length between the first region and the third region, and the third region has a burst strength that under a burst condition retains one or more fragments of the turbine disc/blisk.

  • Patent number: 8959913
    Abstract: Various apparatuses and systems are provided for a turbocharger. In one example, the turbocharger system includes a first turbine having an exhaust flow outlet and a second turbine having an exhaust flow inlet. The turbocharger system further includes a transition conduit fluidically coupling the outlet of the first turbine to the inlet of the second turbine, the transition conduit including an expansion region upstream of a first bend, and a bypass which routes exhaust flow around the first turbine, the bypass having an exhaust flow outlet fluidically coupled to the transition conduit downstream of the expansion region.

  • Patent number: 8858156
    Abstract: A fragment containment assembly for a turbine is provided. The fragment containment assembly includes a plurality of bands disposed around a shroud of the turbine and positioned such that the shroud is disposed between blades of the turbine and the bands along radial directions outwardly extending from a shaft of the turbine. The bands include a material having a first modulus of toughness parameter that is greater than a second modulus of toughness parameter of the shroud at temperatures of at least 260 degrees Celsius. The bands are disposed around the shroud to prevent debris of the turbine from being released outside of the bands along the radial directions caused by failure of the turbine.

  • Publication number: 20110307127
    Abstract: Methods and systems are provided for operating a vehicle including an engine comprising a turbocharger including a compressor and a turbine. The engine further includes a bypass path configured to selectively route gas from downstream of the compressor to upstream of the turbine. In one embodiment, the method comprises selectively increasing gas flow to the engine by adjusting gas flow through the bypass path from downstream of the compressor to upstream of the turbine. In this manner, the performance of the engine may be adjusted for various operating conditions.

  • Patent number: 7921646
    Abstract: A turbocharger is disclosed that includes a compressor, a turbine connected to the compressor by a mechanical shaft, and a fluidic drain valve in flow communication with an air bleed port of the compressor and an exhaust plenum to drain water accumulated inside the turbocharger such that water accumulated in the exhaust plenum is drained during shutdown when no air from the bleed port flows through the fluidic drain valve.
