A gas turbine including a plurality of hook elements disposed one inside the other and designed substantially in the form of hollow cones or hollow cylinders, and including a stator blade support, is intended to enable an especially high efficiency while maintaining the greatest possible operating safety and operating life. To this end, at least one of the hook elements or the stator blade support has a substantially elliptical cross-sectional contour.

Gas turbine

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.
