  • Patent number: 11131322
    Abstract: A structural subassembly for a compressor of a turbomachine, which has a rotor having a plurality of blades, which extend radially in a flow path of the turbomachine, and a compressor casing, which forms a flow path boundary, which delimits the flow path through the turbomachine radially on the outside. In this subassembly, the compressor casing has casing structuring adjoining the rotor. It is envisaged that the compressor casing has a plurality of circumferential segments, which extend in the circumferential direction, wherein only one or only some of the circumferential segments forms or form casing structuring.
    Type: Grant

  • Patent number: 10344616
    Abstract: A stator device for a continuous-flow machine with guide vanes circumferentially distributed on a housing. The guide vanes are respectively embodied with a blade leaf and at least one platform. The platforms form a surface of an annular channel through which working fluid flows. A flow area is provided via which, during operation of the stator device, a working fluid flows on a side of the platform that is facing away from the annular channel from a pressure side of the blade leaf to a suction side of the blade leaf at least in certain areas in the radial direction of the stator device. At least one suction appliance is provided which adjoins the flow area and is formed by a recess, and via which working fluid can be conducted out of the flow area during operation of the stator device.

  • Publication number: 20160376915
    Abstract: A stator device for a continuous-flow machine includes guide vanes circumferentially distributed around a housing. The vanes have respectively one blade leaf and a platform. The platforms form an annular channel through which working fluid flows. At least one platform is arranged in the axial direction between a first point of the channel arranged at 10% of an axial extension of the platform to a central longitudinal axis of the platform upstream of a front of the platform and a second point of the channel arranged at 10% of the axial extension of the platform to a central longitudinal axis of the platform downstream of a rear of the platform. At least one edge area of the platform projects into the channel in the radial direction of the stator device with respect to a rectilinear connection of the two points.
