Definitions
- the invention relates to the manufacture of an impeller for an axial or centrifugal compressor intended to equip a turbomachine such as a turbojet.
- an impeller 1 of a centrifugal compressor is a generally one-piece part comprising a hub 2 having a shape of revolution about an axis AX carrying blades 3. These blades are curved walls of oblique orientation with respect to to the axis AX, spaced from each other around the axis AX.
- hub 2 has an external face 4 on the air stream side which is axisymmetric, in the form of a pavilion which extends from an intake end 6 to a exhaust end 7 where it has a generally essentially radial shape.
- each blade 3 When it is mounted in the turbomachine, the impeller is surrounded by a casing (not shown), called a cover, also having the shape of a bell and whose internal face is bordered by the tops of the blades 3, that is to say their outer edges.
- a casing not shown
- the fluid admitted around the inlet end 6 is compressed by passing between the blades 3, then is discharged more or less radially at the level of the end 7.
- each blade 3 has a generally very left shape having a strongly inclined orientation with respect to the axis AX and a shape twisted around an axis normal to the axis AX.
- these blades 3 have relatively small thicknesses and whose law results from a compromise of aeromechanical optimization.
- an axial compressor wheel such as the wheel 9 of FIG. 3 itself also comprises a hub 11 carrying blades 12 more or less regularly spaced around its axis AX.
- the hub has an essentially cylindrical or slightly conical outer face, and the blades 12 are they also strongly curved and inclined in relation to the axis AX.
- the fluid is compressed while passing through the blades while being discharged in an essentially axial direction.
- such a centrifugal impeller or such an axial wheel are made from a blank piece of alloy such as the rough 8 shown in Figure 2, which is machined with a CNC milling machine equipped with a round milling cutter.
- optimization of performance leads to the design of blades with increasingly complex geometries: if the shapes are generally highly three-dimensional and have a significant inclination and twist, the optimizations lead to increasingly exotic shapes with, for example, blade tops in the so-called bathtub shape and / or with offsets, as well as with very worked or reinforced leading edges.
- the aim of the invention is to provide a manufacturing solution making it possible to extend the range of blade shapes that can be manufactured.
- the invention relates to a method of manufacturing a centrifugal or mixed impeller, or an axial compressor wheel comprising a hub bearing blades, comprising the steps of:
- the invention also relates to a method thus defined, in which one of the steps for adding localized material is a step in which the material added to a blade differs from the material constituting this blade.
- the invention also relates to a method thus defined, in which at least one of the steps of localized addition of material is a step in which material is added to a tip of a blade, this material being more abrasive than the blade. constituent material of the blade.
- the invention also relates to a method thus defined, in which at least one of the steps of localized addition of material is a step in which material is added to a leading edge of a blade, this material being more lasts than the material of the blade.
- the invention also relates to a method thus defined, further comprising a machining and / or polishing step carried out between two steps of adding localized material.
- the invention also relates to a compressor comprising a centrifugal or mixed impeller, or an axial wheel, manufactured according to a method thus defined.
- the invention also relates to a turbomachine comprising a compressor thus defined.
- FIG. 1 already described is an overall perspective view of a known centrifugal impeller
- FIG. 2 already described is an overview showing the manufacture of a centrifugal impeller by milling
- FIG. 3 already described is an overall view of an axial wheel
- FIG. 4 is a schematic representation of an additive manufacturing process by localized addition of material
- FIG. 5 is an overview of a blank part used for implementing the method according to the invention.
- FIG. 6 is an overview of a centrifugal impeller manufactured in accordance with the invention.
- the idea at the base of the invention is to start from a blank part delimiting at least the hub of the impeller, and to complete this blank part to form or finish the blades with an additive manufacturing process of the fusion / sintering type by projection of powder or other addition of material, that is to say by which a localized addition of material is carried out.
- an additive manufacturing process of the fusion / sintering type by projection of powder or other addition of material, that is to say by which a localized addition of material is carried out.
- SLM process meaning Selective Laser Melting
- projection fusion / sintering processes allow localized material additions to be made with a nozzle positioned on the feed zone. also designated by BPP (Blown Powder Process).
- the locally added material can also be supplied in the form of wire to be melted according to the WFP (Wire Fed Process) process.
- LMD Laser Metal Deposition
- CLAD Direct Additive Laser Construction
- the invention consists of making a spinning wheel from a blank such as blank 21 of Figure 5 having incomplete blade elements in the form of blade primers or completely without blades, and adding or supplementing them. blade elements 22 of this blank.
- Part 21 is, for example, the result of forging and milling in order to guarantee a high level of mechanical characteristics, in particular with regard to fatigue, and the local addition of material with an additive manufacturing process of the fusion / sintering type by projection makes it possible to produce complex shapes at the level of the blades.
- the nozzle 14 is positioned vertically while being oriented downwards as in FIG. 4, and the blank 21 is moved relative to this nozzle 14, for example by being carried by a robotic arm.
- Material can thus be brought onto an outer edge 23 of a blade element 22 by positioning this outer edge 23 under the nozzle 14, and by moving the part 21 so that the nozzle 14 runs the entire length of this edge. exterior 23 in order to deposit one or more layers of additional material. Once one or more layers have been added to a blade element 22, the part is rotated around its axis of symmetry AX to place the outer edge of the next blade element opposite the nozzle. 14 to proceed in the same way on this other element.
- each pass consists of the addition of one or more layers of metal on the various elements of the blades, and the entire impeller is formed in several passes of this type. Accessibility is thus optimal and identical for the different blade elements throughout the process.
- This solution also makes it possible to retouch the side faces of the blades during their manufacture, for example to polish these faces as they are constructed, that is to say while they are still easily accessible.
- the blank 21 comprises blade elements 22 which are completed by the additive manufacturing operation to form complete blades. But the blank 21 can also be completely devoid of blades by being reduced to a hub, in which case each blade is entirely formed on this blank 21 by additive manufacturing.
- the blank can also include blades that additive manufacturing can complete by adding, for example, material on the leading edges and on the tops of the blades, that is to say their outer edges, the process then essentially constituting a spinning wheel finishing operation.
- the starting point of the construction may be an axisymmetric disc resulting from turning, or possibly a so-called “3D” milled hub disc, for example in titanium or nickel, or even a hub whose face external already carries more or less complete blade elements as in the example of Figure 5.
- 3D so-called “3D” milled hub disc
- each blade 26 further comprises a top 27 on which material has been added by additive manufacturing.
- This addition on the tops 27 can advantageously consist of an abrasive material making it possible to dispense with the abradable material usually provided on the internal face of the cover surrounding the impeller when it is in use.
- the impeller is made of titanium, which may catch fire in the event of direct contact with the cover
- the addition of a material other than titanium at the top of the blade and ideally abrasive compared to the material of the screw cover -à-vis makes it possible to increase the robustness of the spinning wheel to the button: the risk of fire is reduced if the blades come into contact with the internal face of the cover, so that the internal face of the cover no longer has to be covered of an abradable material.
- material has also been added by additive manufacturing to the leading edges 28 of the blades 26, in this case an alloy which is harder and / or more resistant to impacting erosion than that used to form the body of the blades, so as to have better resistance to impact from foreign bodies and / or to erosion by small particles (sand, dust, volcanic ash, etc.) entering the compressor.
- an alloy which is harder and / or more resistant to impacting erosion than that used to form the body of the blades, so as to have better resistance to impact from foreign bodies and / or to erosion by small particles (sand, dust, volcanic ash, etc.) entering the compressor.
- the invention is implemented with the additive manufacturing process by adding localized material LMD (Laser Metal Deposition), but the process according to the invention can be implemented with other additive manufacturing processes by localized addition of material.
- LMD Laser Metal Deposition
- the method according to the invention can advantageously be implemented with a so-called combined machine ensuring both additive manufacturing operations and milling operations implemented during the construction process of the blades.
- the milling operations are carried out as the blades are built, for example to restore the surface condition of the lower surface and upper surface faces, or correct the thickness, as and when as they are built by additive manufacturing, that is, while they are easily accessible.
- the combination according to the invention of an additive manufacturing process by adding localized material with a displacement of the part relative to the material supply nozzle makes it possible to manufacture blades having more geometries. complex than with an SLM type powder bed additive manufacturing process.
- the inclination of the face downwards of the part is limited to a maximum value, beyond which the powder of the deposited bed cannot hold, preventing the formation of the desired geometry.
