    摘要： A method and an apparatus for measuring a deflection of a rotor of a turbomachine are presented. An optical fiber is inserted through a central bore of the rotor such that the optical fiber extends lengthwise through the bore along an axial direction of the rotor. The optical fiber is made up of a plurality of fiber optic strain sensors along the length of the optical fiber. A shape of the optical fiber is reconstructed based on strain information obtained from the plurality of the fiber optic strain sensors. A rotor deflection parameter is determined from the reconstructed shape of the optical fiber.

    摘要： 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.

    摘要： A blade tip clearance system includes first and second control rings. The first control ring has a first coefficient of thermal expansion (CTE) and a first thermal response rate. The second control ring is located radially outward of and operatively connected to the first control ring and has a second CTE that is different from the first CTE and a second thermal response rate that is different from the first thermal response rate. Thermal expansion and contraction of the first and the second control rings controls a radial position of the blade tip clearance system relative to a rotating blade component.
