Abstract: A turbine guide apparatus, having multiple guide blades. Each guide blade has a first shroud and a second shroud formed on radial ends of a blade leaf having a first carrier for the guide blades. Each guide blade is fastened to the first carrier via a first shroud projection having a second carrier for the guide blades and is fastened on the second carrier via a second shroud projection. The first shroud projection is inserted into a groove of the first carrier in the radial direction and fastened in this groove via a bolt extending in the axial direction through the projection of the first shroud with radial mobility in this groove. The second shroud projection of the guide blade is fastened in the circumferential and radial direction via a pin extending in the axial direction into the projection of the second shroud and the second carrier.

Abstract: A blade of a turbo machine, having a blade leaf, with a flow leading edge, a flow trailing edge, and flow conducting surfaces, and a cooling passage integrated in the blade leaf. In the region of the blade leaf cooling passage portions extend substantially in the radial direction. Adjacent cooling passage portions merge into one another via a diversion passage portion having a material web extending between the adjacent cooling passage portions. The respective material web ends in the region of the respective diversion passage portion. The respective material web has a defined axial width between the respective adjacent cooling passage portions and the respective material web in the region of the respective diversion passage portion has a material thickening enlarging the axial width by at least 20%.

Abstract: A moving blade of a turbo machine, having a leading edge, a flow trailing edge, flow conduction faces, and a blade root mounting the moving blade to a hub body. The blade root is fir tree-like with projections spaced apart from one another. An inner shroud is arranged between the blade leaf and the blade root. A cooling passage is integrated in the blade leaf and the blade root for a cooling medium. An inlet of the cooling passage is formed on the blade root formed of a first inlet passage portion and a second inlet passage portion and a material web extends there between. The first inlet passage portion and the second inlet passage portion merge into a unifying passage portion arranged radially outside the uppermost projection of the blade root and radially inside of the inner shroud.

Abstract: A compressor, in particular, of a turbomachine. The compressor comprises at least one blade ring and at least two ring segments, wherein the blade ring has at least two equally large ring segments. The compressor also comprises blades, which are arranged in the ring segments of the blade ring in such a way that a first number of blades is arranged in a first ring segment and a second number of blades is arranged in a second ring segment. The first number of blades is not equal to the second number of blades.

Abstract: A cooling system for cooling a turbine blade with a cooling fluid via an internal flow passage formed in the turbine blade extending from an inlet to an outlet edge having a first passage section defining a first flow direction, a second passage section defining a second flow direction, a wall between the first and second passage section and a diverter, between the first and the second passage section. The wall in a region of the diverter forms a pier head which extends into the region of the first passage section and thereby reduces the flow cross section of the flow passage.
