Abstract:
A compressor arrangement has a common shaft, an axial compressor having at least a single-stage, and a radial compressor having at least single-stage. Assemblies of the, or each, axial compressor stage on the rotor side and assemblies of the, or each, radial compressor stage on the rotor side are attached to a common shaft (4). A ratio between a maximum diameter of the shaft (4) in the region of the axial compressor (2) and a minimum radial impeller seat diameter of the shaft (4) in the region of the radial compressor (3) is between 1.5 and 3.0.

Abstract:
The invention relates to an electric motor (10) and to a method for producing said electric motor, especially for adjusting mobile parts in a motor vehicle. Said electric motor comprises a collector (36), arranged on an armature (38) and electrically contacted via hammer brushes (12). The armature (38) is surrounded by a lower housing part (32) and an upper housing part (34) which can be assembled in a radial direction (50) in relation to the armature (38). The hammer brushes (12) comprise one fastening element (26) each which engages directly in a seat (30) of the lower or upper housing part (32, 34).
Abstract:
Gear drive unit (10) with a plug-in electronics module (44), in particular for adjusting moving parts in a motor vehicle, comprising an electric motor (12) which has an armature shaft (18), a lower housing shell (14) and an upper housing shell (16), which housing shells can be joined together radially with respect to the armature shaft (18) at a separating plane (32) and enclose the electric motor (12), wherein an electronics interface (42) for receiving a plug-in electronics module (44) is arranged on the lower housing shell (14), and the electronics interface (42) has a sealing plane (54) between an outer face (40) of the lower housing shell (14) and the plug-in electronics module (44), this sealing plane been arranged at least approximately parallel to the separating plane (34).
Abstract:
A component can be subjected to hot gas. At least one duct is provided which can be subjected to a cooling fluid. The duct is bounded by two first walls opposite to one another. The walls include turbulators with the same direction of inclination. In order to avoid constrictions, the turbulators of the first wall have a different angle of inclination relative to a flow direction of the cooling fluid to the turbulators of the second wall.
Abstract:
A method is for producing a turbine blade, in particular, a gas turbine blade, comprising a head, a foot, and a blade section, in addition to an internal canalization system, including individual channels through which coolant gas can pass along a flow path within the turbine blade. The turbine blade also includes a throttle device which influences the passage of the coolant gas without impairing the flow of the coolant gas in the intake area. The throttle device is located in the rear section of the flow path, and is positioned upstream of the exit openings.
Abstract:
A rotor blade of an axial compressor includes: a blade root; and a blade leaf. The blade leaf has: a flow inlet edge, a flow outlet edge, a pressure side extending between the flow inlet edge and the flow outlet edge and a suction side extending between the flow inlet edge and the flow outlet edge, which together define a blade profile of the blade leaf in Cartesian coordinate values x, y and z such that first and second profile coordinates, or the coordinates x and y when joining via continuous arcs, each describe a smooth profile section on a radial section height along a third profile coordinate, or the coordinate value z, and the joining of the radial profile sections with a smoothing function describe the blade profile of the blade leaf.
