摘要： The invention relates to a blade (1) for a turbine engine (41) with a base body (2), made from a titanium alloy, with a first and a second component piece (11,13), which are connected in a connection region (31) by means of a bonding process. A groove (23) with a groove wall (27) runs through the connection region (31), to prevent local concentration of tension, such that the above borders directly on the second component piece (13) and forms therewith a connection angle (α) greater than 70 degrees.

摘要： The invention relates to a device for producing a metallic hollow body (1) with at least one hollow space (3, 5, 17) and a wall surrounding said hollow space. Said device comprises an outer casting mould which has at least one inner core (33, 35, 47) for forming the hollow space. The outer casting mould is configured in such a way that it can be split into at least two outer parts (29A, 29B). The inner core (33, 35, 47) is connected to an outer part (29A, 29B) of the outer casting mould by at least one connecting element (53), said connecting element being used to configure a through opening in the wall (23) extending into the hollow space (3, 5, 7).

摘要： The invention relates to a cast turbine blade (1), comprising a blade (5) and a platform area (7), especially a gas turbine guide blade. The platform area (7) is formed by a hot gas platform (9) on the hot gas side and an opposite load platform (11). The load platform (11) absorbs the forces enabling a thin configuration of the hot gas platform (9). Particularly little heat stress occurs.

摘要： The invention relates to a turbine bucket (1), comprising an interior space (5) through which a cooling liquid (12) is guided and wherein supporting ribs (7) are arranged. Cold insulation plates (11) are arranged in front of the support ribs (7) to reduce thermal stresses. These plates restrict the cooling of the support ribs (7). The inventive turbine bucket (1) is preferably a gas turbine bucket (1).

摘要： The invention relates to a component (10) that can be subjected to a hot gas, especially a turbine blade. At least one channel (13) is provided. Said channel can be subjected to a cooling fluid and is delimited by two first walls (16, 17), which face each other and have turbulators (20, 21) with the same direction of inclination. The turbulators (20) of the first wall (16) have a different angle of inclination (α) in relation to a direction of flow (22) of the cooling fluid to the turbulators (21) of the second wall (17) in order to avoid constrictions (23).

摘要： The invention relates to a turbine vane (1), especially a turbine vane of the last stages, respectively comprising a lower area (2) which is radially and externally arranged, an upper area (3) which is radially and internally arranged, and a radial cooling air channel (4) extending between the upper area and the lower area. Cooling air (23) can be introduced into said channel via an inlet (36) in the lower area, and can be at least partially discharged via an outlet (35) in the upper area. The cooling air channel comprises a radial inner channel through which the cooling air flows from the lower area to the upper area, and an outer channel (9) which is adjacent to the inner channel and which at least partially surrounds the inner channel on the circumferential side thereof. Said outer channel communicates with the inner channel and comprises an outlet (12) which is arranged in the lower area. Part of the cooling air (41) flows back in the direction of the lower area via the outer channel and emerges via the outlet.

摘要： The invention relates to a turbo-machine (1) comprising a rotor (25) that extends along a rotational axis (15). Said rotor (25) has a peripheral surface (31) which is defined by the outer radial delimitation surface of the rotor (25) and has a receiving structure (33) as well as a first moving blade (13A) and a second moving blade (13B). Each moving blade comprises a blade footing (43A, 43B) and a blade platform (17A, 17B). The blade platform (17A) of the first moving blade (13A) and the blade platform (17B) of the second moving blade (13B) border one another, and a gap (49) is formed between the blade platforms (17A, 17B) and the peripheral surface (31). A sealing system (51) is provided in the gap (49) on the peripheral surface (31).

摘要： The invention relates to a guide blade (17) for a fluid-flow machine (1), notably a gas turbine guide blade, in which the platform (48) has a separating area (50) which is configured as a separate component. This is advantageous notably as it simplifies the manufacture of cast blades (17), permits the use of a greater variety of materials and application of a high-quality protective coating and improves cooling efficiency.

摘要： The invention relates to a gas turbine rotor with an internally cooled gas turbine blade (1) which has a blade foot (2) and a blade platform (5), said blade platform having recesses (10) into which strip inserts (11) are introduced. The aim of the invention is to configure a gas turbine rotor of this type in such a way that the seal that is provided to prevent hot gas from entering and cold air from leaving and the fixing means of the gas turbine blade (1) can be produced simply and inexpensively while still being very reliable. To this end, the recess (10) extends as far as a plate-end base (13) of the blade platform (5) and the strip insert (11) has a positive fit on the plate (4) which prevents axial displacement in a direction of use (30) of the gas turbine blade (1).

摘要： The invention relates to a turbine (1) and a method for dismantling a blade (12) of a turbine. Said turbine (1 ) comprises a rotor (3) that extends in an axial direction and an accessible combustion chamber (6), which communicates with an annular hot-gas conduit 18, in which a plurality of blades (12) that form a blade row (13) is arranged. Each blade (12) has a blade root (21) that is fixed to the internal housing and a blade head (22) that lies opposite said root (21) and faces the rotor (3), said head being fixed to a fixing ring (24) of the turbine (1) that encircles the rotor (3). The aim of the invention is to reduce the down time of the turbine (1) during repair, inspection and/or maintenance work. To achieve this, the blade root (21) and/or the blade head (22) can be fixed by means of a manually detachable clamping device (25, 35).
