摘要： The invention relates to a gas turbine (1). The aim of the invention is to provide an axial sealing between a vane ring (11) and a moving blade ring (13), which has an excellent sealing effect, is easy to install and inexpensive to produce. For this purpose, a sealing element (35) is used that extends across at least a fourth of the hot gas channel circumference. Preferably, said sealing element extends across approximately half the circumference and is inserted in grooves of the vane support (79) and the vane platforms.

摘要： The invention relates to a combustion chamber (4) of a gas turbine (1), inside of which a supplied fuel is reacted with supplied combustion air in order to produce a working medium (M). The inside of the combustion chamber wall (24) is provided with a lining formed from a number of heat shield elements (26). The or each heat shield element (26), together with the combustion chamber wall (24), forms an interior space (27) that can be subjected to the action of a coolant (K). The aim of the invention is to provide a combustion chamber with a comparatively simple design that has a high system efficiency. To this end, the invention provides that a flow element (49) is placed in the respective interior space (27) while serving to effect a locally specific control of the flow of coolant.

摘要： The invention relates to a gas turbine (1) having a combustion chamber arrangement and a turbine chamber (2) connected downstream of said combustion chamber arrangement, wherein the combustion chamber arrangement includes a plurality of individual combustion chambers (3) formed by input areas (4) and transition areas (5) converging in an annular gap leading to the turbine chamber and wherein the longitudinal axes (B) of the individual combustion chambers are placed at an angle relative to an engine axis (M) that is defined by the axial extension of the turbine chamber (2). In order to improve said gas turbine by visibly reducing the thermal and mechanical loads of the individual combustion chambers in the transition area so that cooling requirements can be lowered in said area, the transition area (5) of at least one individual combustion chamber (3) and a corresponding input area (9) of the turbine chamber (2) are embodied in such a way that the gas flow running from the at least one individual combustion chamber (3) into the turbine chamber (2) is deflected in the direction of the engine axis (M) and substantially in the input area (9) of the turbine chamber (2).

摘要： The invention relates to a turbine (6), especially a gas turbine. According to the invention, a sealing element (44) with a receiving area (50) is provided for sealing the guide blades (18) which are adjacent to each other in the peripheral direction (36) of the turbine (6). The foot plates (21) of the guide blades (18) extend into said receiving area. The edge area of the foot plates (21) does not have to be reinforced compared to a conventional seal, which enables the entire foot plate to be cooled homogeneously. A closed cooling system (62) can therefore be used for cooling, especially with steam.

摘要： The invention relates to a cast gas turbine blade (1) that is flown through by a coolant. Said gas turbine blade (1) comprises a footing of the blades (2) which is provided with several supply channels (4) and a distribution chamber (5). A coolant can be fed to the supply channels (4) by means of a feeding channel (6) of the disc (3). The feeding channel (6) communicates with the supply channels (4) via the distribution chamber (5). The aim of the invention is to optimise the flow and the production of said gas turbine blade (1). To this end, a cast distribution chamber (5) is provided that has supply channels (4) which are provided with rounded or flattened admission openings (7). The cast distribution chamber (5) is produced by a one-piece casting core.

摘要： The invention relates to a turbine blade (1) through which cooling liquid flows and which comprises several flow channels (4, 5, 6) that are adjacently arranged in the flowing-off direction (2) of the working fluid (3). Said flow channels (4, 5, 6) extend between inflow openings (7, 8, 9), which are located on a radially inner blade foot (10), and outflow openings (11, 12, 13), which are situated opposite the blade foot in a more radially outer manner. The flow channels (4, 5, 6) extend such that the local radial flow components (15) of the resulting cooling fluid stream (14) are directed outward in a, for the most part, predominantly radial manner. A flow channel (4), which is in the front when viewing in the flowing-off direction (2), is provided whose outflow openings (11) are placed inside a touching edge (16) of the turbine blade (1). In addition, at least one rear edge channel (5, 6) is provided whose associated resulting cooling fluid stream (14) additionally comprises local cross-flow components (17) and whose outflow openings (12, 13) are placed inside a rear edge (16) of the turbine blade (1).
