Definitions
- Vane ring Vane ring and method for producing the same
- the invention relates to a vane ring according to the preamble of claim 1. Furthermore, the invention relates to a method for producing a vane ring and a method for producing guide vanes for a vane ring.
- the most important materials used today for aircraft engines or other gas turbines are titanium alloys, nickel alloys (also called superalloys) and high-strength steels.
- the high strength steels are used for shaft parts, gear parts, compressor casings and turbine casings.
- Titanium alloys are typical materials for compressor parts.
- Nickel alloys are suitable for the hot parts of the aircraft engine.
- gas turbine components made of titanium alloys nickel alloy or other alloys are known from the prior art primarily investment casting and forging. All highly stressed gas turbine components, such as components for a compressor, are forgings. Components for a turbine, however, are usually designed as precision castings.
- Powder metallurgical injection molding is an interesting alternative for the manufacture and production of complex components.
- Powder metallurgical injection molding is related to plastic injection molding and is also referred to as metal mold injection or metal injection molding (MIM).
- MIM metal injection or metal injection molding
- Gas turbines have stator vane rings in the area of a compressor and in the area of a turbine, wherein a vane ring comprises a plurality of guide vanes which are fastened to a guide vane carrier ring.
- the vanes are typically soldered to the vane support ring.
- the guide vanes and the vane support ring are made of an identical material.
- the present invention based on the problem to provide a novel vane ring and a method for producing the same.
- the vane support ring and the vanes are made of different materials, the material of which the vanes are made being more valent than the material of which the vane support ring is made.
- the guide blade carrier ring and the guide vanes are manufactured from different materials, wherein the material of the guide vanes is of higher quality than the material of the guide vane carrier ring. This makes it possible to provide a tailored to the thermal and mechanical requirements Leitschaufelkranz while optimizing the cost.
- the vane support ring and the vanes are each made of a nickel-based alloy, wherein the nickel-based alloy from which the vanes are made is more heat-resistant than the nickel-base alloy from which the vane support ring is made.
- the inventive method for producing a vane ring is defined in claim 5.
- a method for manufacturing vanes for a vane ring is defined in claim 11.
- FIG. 1 a plurality of jointly produced guide blade blanks; and FIG. 2 also shows a number of jointly manufactured guide blade blanks.
- the present invention relates to a vane ring of a turbomachine, in particular of a gas turbine designed as an aircraft engine.
- a vane ring has a plurality of vanes attached to a vane support ring.
- the guide blade carrier ring and the guide vanes are manufactured from different materials.
- the vane support ring is made of a first material
- the vanes are made of a second material
- the material from which the vanes are made is superior to the material from which the vane support ring is made.
- a higher-grade material is to be understood in particular to mean that it has a higher heat resistance and is therefore more heat-resistant.
- the vane support ring of the vane ring is made of the nickel-based alloy IN 718.
- the vanes are made of a higher quality or higher heat resistant nickel base alloy, namely the nickel base alloy UDIMET 720.
- the vanes are soldered to the vane support ring.
- the procedure is such that the guide blade carrier ring is produced from the first material, in particular from the nickel-based alloy IN 718, in particular by forging.
- the guide vanes are made of the second material, in particular of UDIMET 720, preferably by powder metallurgical injection molding.
- FIGS. 1 and 2 each show such blanks 10, 11 produced by powder metallurgical injection molding from a plurality of guide blade blanks 12 and 13, respectively.
- the guide blade blanks 13 in the blank 11 are stacked one above the other in the radial direction, so that adjacent guide blade blanks 13 are connected via webs 15 such that a guide blade tip of a guide blade blank 13 is connected to the guide blade root of the adjacent guide blade blank 13 via a web 15.
- Powder metallurgy injection molding is also referred to as Metal Injection Molding (MIM).
- MIM Metal Injection Molding
- the vane blanks produced by powder metallurgy injection molding are made by milling or grinding or an electrochemical Machining (ECM) process edited.
- ECM electrochemical Machining
- the machining of the guide blade blanks preferably takes place by means of a Precise Electrochemical Machining (PECM) process.
- vanes preferably made by a combined MIM process and PECM process, are inserted into and soldered to the vane support ring and then heat treated thereon to produce the vane ring so produced to provide optimum stator vane rigidity.
