A stator blade carrier for a gas turbine is provided. The stator blade carrier includes a plurality of axial segments. At least one axial segment is designed as a tubular lattice structure. This allows a simpler design technically and a more flexible adaptation to the temperature profile present on the stator blade carrier to maintain operational safety.

The invention relates to a device for support of an adjusting ring which encompasses at a distance a basically circular blade carrier, which adjusting ring is rotatable in the circumferential direction around a center axis which is identical with the blade carrier, in order to adjust radially extending blades of a ring of a turbo-engine, wherein a plurality of levers are provided between the blade carrier and the adjusting ring, which levers are distributed over the circumference, extend tangentially in each case, and which on their free ends have a rotatable roller in each case, which are rollable in the circumferential direction on the adjusting ring or on the blade carrier. According to the invention, the lever is tightly clamped on one side to disclose a wear-free and reliable device for support of an adjusting ring which encompasses at a distance a circular blade carrier.

The invention refers to a device for determining the angular position of a compressor stator blade, which is rotatable around its longitudinal axis and arranged in a compressor, with which is associated a measuring surface which rotates synchronously with it. For a reliable, simple and approximately error-free recording of the angular positions, the angular position of the compressor stator blade can be determined via the device in an automated manner. For this purpose, it has at least one mounting unit provided for aligned fastening of the device on the compressor, and at least one measuring and evaluating unit which comprises at least two distance sensors which each record a distance to the measuring surface which is rotatable from the reference position, as a result the angular position of the measuring surface, relative to the reference position depends upon the two recorded distances, is determined by the measuring and evaluating unit.
