摘要： The invention relates to a low-pressure turbine of a gas turbine. The turbine comprises a number of stages arranged one behind the other in an axial manner in the flow-through direction of the turbine. Each stage is formed from a fixed vane ring having a number of vanes and from a rotating blade ring having a number of blades. Each stage is characterized by a characteristic value vane-to-blade ratio that indicates the ratio of the number of vanes to the number of blades within a stage. One of the stages of the turbine is designed in such a manner that, in the event of noise-critical conditions of the turbine, the characteristic value vane-to-blade ratio of this stage is between a lower cut-off limit for mode k=-1 of the blade passing frequency (BPF) of said stage and an upper cut-off limit for the mode k=-2 of the blade passing frequency (BPF) of this stage.

摘要： A method for producing a hole in an object comprises the generation of a beam for removing material such that a bottom of a borehole is placed in a focus position of the beam, and a removal of material by impingement of the beam on the bottom of the borehole. A repeated placing of the bottom of the borehole in a focus position of the beam in order to compensate for the increased depth of the hole as a result of the removal of material is combined with a step of changing a radiation characteristic of the beam when the bottom of the borehole is repeatedly placed in a focus position.

摘要： The invention relates to a method for machining a metal component, particularly a component of a gas turbine, by machining the component with the help of a pulsed electrochemical removal process, the component having a preliminary contour that is to be finished and has different overmeasures. Said method is characterized by the following steps: a) the different overmeasures of the preliminary contour are determined; and b) the component is simultaneously machined on both sides by simultaneously advancing at least one respective electrode that is arranged on different sides of the component, the advancing speed of the electrode being greater in the area of the larger overmeasure of the preliminary contour than the advancing speed of the electrode in the area of the smaller overmeasure of the preliminary contour.

摘要： Linear guide (1), in particular for an apparatus for electrochemical machining, which guides a linear movement of a quill (3), periodically moved in a machine frame (2), in order to periodically vary a working gap between a cathode arranged on the quill (3) and a workpiece in the direction of the longitudinal axis (4) of the quill (3), wherein the quill (3) is connected by a plurality of guide rods (5) to the machine frame (2), and the guide rods (5) are arranged essentially perpendicularly to the longitudinal axis (4) of the quill (3) in the no-load, non-deflected state, and wherein the guide rods (5) have a notch hinge (7) at the connecting point (6) to the quill (3) and at the connecting point (6) to the machine frame (2) in order to permit the periodic linear movement of the quill (3) via said notch hinge (7). A linear guide (1) for the periodic movement of a quill (3) for an apparatus for electrochemical machining can thus be provided which can be varied in any desired manner with regard to the radial or axial rigidity, can be enlarged to a limited extent and has a scalable construction of small size with a simple composition of parts.

摘要： An integrally bladed rotor comprises a rotor main body (12) and a blade unit (16). When producing the rotor, these are initially spaced apart from each other such that a gap (20) forms. An intermediate body (26) is introduced in said gap (20) by way of rotational friction welding in order to bridge the gap (20) and connect the rotor main body (12) to the blade unit (16). As an alternative, the intermediate body (26) is first friction-welded to one of the parts (12, 16) to be connected by rotational motion. The other one of the parts to be welded on is then attached to the resulting integral unit by friction welding.
