Definitions
- the present invention relates to a vane assembly for a turbomachine.
- the turbomachine can, for example, be a jet engine, e.g. B. a turbofan engine.
- the turbomachine is divided into compressor, combustion chamber and turbine.
- the air drawn in is compressed by the compressor and burned in the downstream combustion chamber with added kerosene.
- the resulting hot gas a mixture of combustion gas and air, flows through the downstream turbine and is expanded in the process.
- the turbine also extracts energy from the hot gas to drive the compressor.
- the present subject matter can relate in particular to the compressor area, but in general can also be used, for example, in the turbine.
- the reference to the aircraft engine is intended to illustrate an advantageous area of application, but not initially limit the subject in its generality.
- the present invention is based on the technical problem of specifying an advantageous guide vane arrangement for a turbomachine.
- the vane arrangement according to claim 1 ge This has a guide vane, which is adjustably mounted in a guide vane mount via an axle element in order to change the angle of attack.
- an outer lateral surface of the axle element faces an inner lateral surface of the guide vane mount.
- at least one of these lateral surfaces is provided with a protective coating and the guide vane blade of the guide vane is also provided with a protective coating at least in certain areas.
- the protective coating of the at least one lateral surface can, for. B. prevent wear, especially in the case of a sleeveless design (without white teres bearing element between the lateral surfaces).
- the protective coating in the bearing can enable direct contact between the axle element and the guide vane mount, which, for example, allows for smaller sizes and shapes. It can e.g. B. the vane ring can be made smaller in absolute dimensions and/or a smaller split ratio can be selected, both of which open up creative freedom.
- the lateral surface(s) can be partially or completely coated.
- the guide vane receptacle can therefore be designed as a recess or bore in a housing section of a compressor, which is adapted to receive the axle element in direct contact and to mount it rotatably.
- the manufacturing effort can be limited, for example.
- the protective coatings can e.g. B. have at least one layer in common, which can simplify the application (in terms of throughput and z. B. also regarding any covering effort, see below in detail). From a functional point of view, the protective coating of the airfoil can also prevent wear, e.g. erosion.
- the axle member may be a trunnion or shaft of the vane.
- the adjustment angle i.e. the angle of attack
- the pin which is radially opposite in relation to the longitudinal axis of the flow machine, is used for suspension.
- the guide vane arrangement is preferably designed without bushings both on the journal and on the shaft, ie the journal and the journal guide vane mount lie directly against one another and the shaft and the shaft guide vane mount lie directly against one another.
- At least one of the lateral surfaces is preferably provided with a protective coating for each receptacle.
- the at least one lateral surface and the vane blade have an identical protective coating.
- the protective coatings therefore have, for example, the same structure and/or the same material composition, and they can in particular be of the same thickness.
- the layers or layer systems can be applied in particular at the same time (which saves time and effort).
- the protective coating of the at least one lateral surface is on both the axle element and the vane In other words, both lateral surfaces are tikbe coated.
- only the outer lateral surface can be provided with the protective coating and the inner lateral surface can be uncoated.
- the entire guide vane can be protectively coated. This can further simplify production, for example no covering etc. is required.
- the coating of the at least one lateral surface can generally also be achieved solely by coating the guide vane receptacle. In other words, only the inner surface can be coated and the outer surface can remain uncoated.
- a respective protective coating can also have a multilayer structure, that is to say of at least two layers placed one on top of the other.
- it can also be a single-layer system, ie the protective coating can also consist of a single layer.
- the layers discussed below are intended to be disclosed both as part of a multi-layer system and as a respective single-layer system.
- the separation options described below should also be expressly disclosed with regard to corresponding production processes.
- At least one of the protective coatings has a galvanic layer or consists of a galvanic layer.
- the galvanic layer can, for example, be a chromium layer, e.g. B. hard chrome, or a layer of nickel.
- at least one of the protective coatings may be a chemical layer, e.g. B. electroless nickel or nickel phosphorus (NiP). According to a preferred embodiment, in turn, both in terms of a
- Multi-layer and a single-layer system should be disclosed, is one of the Gas phase deposited layer provided.
- the layer can be applied, for example, by chemical vapor deposition (CVD), in particular also plasma-enhanced chemical vapor deposition (PACVD), or also by physical vapor deposition (PVD).
- CVD chemical vapor deposition
- PVD plasma-enhanced chemical vapor deposition
- PVD/PACVD carbon layer(s) is/are also possible, e.g. B. metal-containing hydrogen-containing amorphous carbon layer(s), aC:H:Me.
- metal for example, a composite of an aC:H matrix with metal carbides can form.
- a possible example is a tungsten carbide-carbon layer (WC/C), a titanium carbide layer (Ti/C) or tantalum carbide layer (Ta/C) or DLC layer (Diamond-Like-Carbon) is also possible.
- Hard material layers for example made of titanium nitride (TiN), titanium carbonitride (TiCN), titanium aluminum nitride (TiAlN) or chromium nitride (CrN), are also possible.
- a metal nitride/metal multi-layer system is also possible, for example available under the ERCoat brand. According to a preferred embodiment, which in turn is a multi-layer or
- a thermally sprayed layer is provided.
- This can, for example, be a tungsten carbide layer, for example WC/Co.
- an alloy is also possible, e.g. B. a cobalt-chromium-molybdenum alloy (e.g. commercially available as Triballoy T-800).
- the axle element is a journal which is located radially on the inside in relation to the longitudinal axis of the turbomachine.
- the axis element is a shaft which is located radially on the outside relative to the longitudinal axis of the turbomachine and via which the adjustment angle is specified for the guide vane.
- both the journal and the shaft are preferably designed without a bushing/bearing element, i.e. both the bearing is designed radially on the inside and the bearing radially on the outside with at least one coated lateral surface in relation to the longitudinal axis.
- the invention also relates to a compressor module with a guide vane arrangement disclosed here.
- the invention relates to a turbomachine, in particular an aircraft engine, with such a compressor module or a guide vane arrangement disclosed herein.
- the invention also relates to a method for producing a guide vane arrangement disclosed here or the corresponding compressor module/turbo machine, the protective coatings being applied at least in regions to the guide vane blade and to at least one of the lateral surfaces.
- the axle element, ie the outer surface area, and the vane blade are protectively coated at the same time, ie in the same process.
- the guide vane blade can be coated in regions (eg defined on the front edge by appropriate covering).
- the vane blade is preferably coated as a whole, in particular the entire vane.
- FIG. 1 is a schematic view of a sheathed power unit in a longitudinal section;
- FIG. 2 shows a guide vane arrangement according to the invention;
- Figure 3 shows a detailed view of Figure 2.
- FIG. 1 shows a section through a turbomachine 1, specifically a jet engine (mantle power engine).
- the turbomachine 1 is divided functionally into compression la, combustion chamber lb and turbine lc.
- Both the compressor la and the turbine lc are each made up of several modules, the compressor la presently from a low-pressure laa and a high-pressure compressor module lab.
- Each compressor module laa, lab is in turn built up from several stages, each stage is in the Generally composed of a rotor blade ring and a subsequent guide vane ring.
- compressor gas 3 in this case air, flows axially through compressor la relative to a longitudinal axis 2, specifically in a compressor gas channel 4.
- Compressor gas 3 is compressed, kerosene is then added in combustion chamber lb, and this mixture is burned
- Figure 2 shows a guide vane arrangement 20 with a guide vane 21 and guide vane mounts 22.
- the guide vane 21 has a guide vane blade 31, which has a front edge 31.1 and a rear edge 31.2, as well as two front and rear edges 31.1, 31.2 connecting side surfaces 31.3. 31.4.
- the guide vane 21 has two axis elements 25, namely a journal 26 radially on the inside and a shaft 27 radially on the outside ).
- the guide vane receptacle 22 can be formed radially on the inside, for example, in a mounting ring 35 ; radially on the outside, the shaft 27 is guided in two mounting rings 36 in this example.
- the mounting of the axle elements 25 is both radially on the inside and radially on the outside designed without bushings, the axle elements 25 are each inserted directly into the respective receptacle 22 . This is achieved by protective coatings 37 in the corre sponding areas.
- FIG. 3 shows such a protective coating 37 in detail.
- a section is shown, the section plane lies parallel to the axis of rotation 28 of the vane blade 21 .
- the axis element 25 can be the pin 26 or the shaft 27 .
- An outer lateral surface 25.1 of the axle element 25 faces an inner lateral surface 22.1 of the receptacle 22.
- the receptacle 22 is designed without a bush, i.e. the receptacle does not have a plain bearing bush, but is formed directly by a recess/bore in a housing part.
- the two jacket surfaces 25.1, 22.1 are each circular.
- the figure illustrates the protective coating 37, in the present case a protective layer 40 is applied to the outer lateral surface 25.1 and a protective layer 40 is also applied to the inner lateral surface 22.1.
- a protective layer 40 is also applied to the inner lateral surface 22.1.
- the components rub against one another via these protective layers 40 (here, for the sake of clarity, a gap is shown between them), so the protective layers prevent wear.
- only the inner lateral surface 22.1 can be provided with the protective layer 40 or only the outer lateral surface 25.1 can be provided with the protective layer 40.
