摘要： The invention relates to an exhaust-gas section (12) for a gas turbine (1), comprising a surrounding shroud (42, 44) having a first opening (48), which is arranged in a region of the exhaust-gas section (12) that has a pressure lower than the air pressure of the outer environment of the gas turbine (1) in an operating state of the gas turbine (1) and which forms the outlet of an air channel (50), the inlet of which is connected to the outer environment of the gas turbine (1). The problem addressed by the invention is that of, by means of said exhaust-gas section, ensuring especially flexible operation of the gas turbine by reliably avoiding exhaust-gas leaks in all operating states. This problem is solved in that the air channel (50) has a chamber (62) at the outlet-side end of the air channel, which chamber has a second opening (64), through which a specified gas mass flow is admitted into the chamber (62).

摘要： The invention relates to a rotor (01) for use in a gas turbine, comprising a plurality of compressor segments (21), a plurality of central segments (31), and a plurality of turbine segments (41); the compressor segments (21) and the turbine segments (41) correspondingly have blade rims (22, 42). In order to better cool the central segments (31) and the turbine rims (42), cooling air ducts (25a, 35, 45a) are used which penetrate the segments (21a, 31, 41a).

摘要： Overall, the invention relates to an internally coolable component for a gas turbine (10) with at least one cooling duct (35), on the inner surface (42) of which swirl elements (46) are arranged in the form of turbulators (46) which extend transversely with respect to the main flow direction of a coolant. In order to reduce pressure losses for the coolant (45) in the cooling duct (35), it is provided that pins (48) with different heights are set up between the turbulators (46).

摘要： The invention relates to an easy to produce, reliable means for the brushes (2; 3) situated on a brush supporting plate (1) of pressing on the commutator, in the form of a tension element (4-10) which is braced essentially crosswise to each brush and extends in the direction of pressure (A) of the brush in the manner of a tension force component. The particularly simple tension element provided by the invention is an O-ring (8) which peripherally tensions all of the ends of the brushes facing away from the commutator. The brush support plate can have protruding guiding webs (1.7-1.10) for brushes which are then preferably only supported by the tension elements and can be exposed to a current.
