Description

本発明は、概してタービンに関し、具体的には、セラミックマトリックス複合材料（ＣＭＣ）部品及び金属シールをセラミックマトリックス複合材料部品に取り付ける方法に関する。   The present invention relates generally to turbines, and more particularly to ceramic matrix composite (CMC) parts and methods for attaching metal seals to ceramic matrix composite parts.

従前、セラミックマトリックス複合材料（ＣＭＣ）を用いるタービンブレード又はノズルのようなタービンエンジン部品の製造に、多くの技術が使用されていた。ＣＭＣ部品の製造方法の一例は、溶融ケイ素を含浸した繊維材料を含む炭化ケイ素マトリックス複合材料の製造であり、Ｓｉｌｃｏｍｐプロセスと呼ばれる。繊維は概して約１４０μｍ以上の直径を有しており、そのため、タービンブレード部品のような形状が複雑で入り組んだものはＳｉｌｃｏｍｐプロセスでは製造することができない。   In the past, many techniques have been used to manufacture turbine engine components such as turbine blades or nozzles using ceramic matrix composites (CMC). An example of a method for producing CMC parts is the production of a silicon carbide matrix composite comprising a fiber material impregnated with molten silicon, referred to as the Silcomp process. Fibers generally have a diameter of about 140 μm or more, so that complex and intricate shapes such as turbine blade components cannot be produced by the Silcomp process.

ＣＭＣタービンブレードの別の製造技術は、スラリー注入溶浸（ＭＩ）プロセスとして知られる方法である。スラリー注入ＭＩ法を用いた製造方法の一例では、ＣＭＣの製造に当たって、まず互いに略９０°の角度をなす２つの製織方向を有していて、それら両方の製織方向に略同数の繊維を有する炭化ケイ素（ＳｉＣ）含有繊維を含む二次元（２Ｄ）均衡織布層のパイルを用意する。   Another manufacturing technique for CMC turbine blades is a process known as a slurry injection infiltration (MI) process. In an example of a manufacturing method using the slurry injection MI method, in manufacturing CMC, first, there are two weaving directions forming an angle of approximately 90 ° with each other, and carbonization having approximately the same number of fibers in both weaving directions. A pile of two-dimensional (2D) balanced woven fabric layers containing silicon (SiC) -containing fibers is provided.

一般に、かかるタービン部品は、隣接金属ハードウェア及び／又は金属表面に取付ける必要がある。金属ハードウェアへのＣＭＣの取付けに伴う２つの短所は、硬い研磨性セラミック材料面による金属ハードウェアの摩耗と、ＣＭＣにおける荷重分配の欠如である。荷重分配は、ＣＭＣ部品とシュラウドのような金属表面との境界で重要である。典型的に、荷重分配を改善するため、ＣＭＣと金属表面の間に金属シム又はセラミック布が挿入される。摩耗は、通例、金属ハードウェアへの皮膜又はノズル取付け面への皮膜の施工によって低減される。   In general, such turbine components need to be attached to adjacent metal hardware and / or metal surfaces. Two disadvantages associated with attaching CMC to metal hardware are metal hardware wear due to hard abrasive ceramic material surfaces and lack of load distribution in CMC. Load distribution is important at the boundary between CMC parts and metal surfaces such as shrouds. Typically, a metal shim or ceramic cloth is inserted between the CMC and the metal surface to improve load distribution. Wear is typically reduced by applying a coating on the metal hardware or a coating on the nozzle mounting surface.

そこで、上述の短所が解消されたセラミックマトリックス複合材料（ＣＭＣ）部品並びにＣＭＣ部品に金属シールを取り付ける方法が当技術分野で望まれてる。   Accordingly, there is a need in the art for ceramic matrix composite (CMC) parts that eliminate the above disadvantages and methods for attaching metal seals to CMC parts.

The CMC component includes a first end portion 14 and a second end portion 16 that faces the first end portion. CMC component 10 includes an impingement baffle cavity surrounded by an outer layer 12. The CMC component 10 is not particularly limited but is a non-rotating component such as a vane or a nozzle. For example, as shown in the figure, the CMC component 10 is a nozzle.

一実施形態では、ＣＭＣ部品は、ＣＭＣ部品の第２の端部に取り付けられたＣＭＣ金属境界部材を含んでおり、ＣＭＣ金属境界部材は、ロータパージが必要とされるときに空気を分配するためにＣＭＣ部品の下方でプレナムを形成する。例えば、図１及び図２に示すように、ＣＭＣ部品１０は、ＣＭＣ部品１０の第２の端部１６に取り付けられたＣＭＣ金属境界部材５０又はシールボックスを含む。ＣＭＣ金属境界部材５０は、ロータパージが必要とされるときに空気を分配するためにＣＭＣ部品１０の下方でプレナムを形成し得る。図２に示すように、ロータパージに用いる空気は、符号１２０で示す矢印である。一実施形態では、図に示すように、ＣＭＣ金属境界部材５０は、単一のＣＭＣ部品１０に延在する。別の実施形態では、ＣＭＣ金属境界部材５０は、複数のＣＭＣ部品１０に延在し、ＣＭＣ部品１０の周りで最大３６０°の完全なリングをなす。ＣＭＣ金属境界部材５０の材料としては、特に限定されないが、金属、金属合金及びこれらの組合せが挙げられ、例えば、合金は、ニッケル基超合金、コバルト基超合金及びこれらの組合せを含む。ＣＭＣ金属界面５０は、静止シール４０に隣接する流路５４へと出る供給管６０を含む。例えば、図１及び図２に示すように、供給管６０は、ＣＭＣ金属境界部材５０からインピンジメントバッフル空洞３０に突出していてもよい。別の実施形態では、供給管６０は、インピンジメントバッフル空洞３０からＣＭＣ金属境界部材５０に下向きに延在していてもよい。他の実施形態では、プレナムを形成するために供給管６０を用いる代わりに、取付け部材７０は、ロータのパージ空気１２０を受容するための流路又は開口(図示せず）を含む。別の実施形態では、ＣＭＣ金属境界部材５０は加圧されなくてもよい。   In one embodiment, the CMC part includes a CMC metal boundary member attached to the second end of the CMC part, the CMC metal boundary member for distributing air when a rotor purge is required. A plenum is formed below the CMC part. For example, as shown in FIGS. 1 and 2, the CMC component 10 includes a CMC metal boundary member 50 or seal box attached to the second end 16 of the CMC component 10. CMC metal boundary member 50 may form a plenum below CMC component 10 to distribute air when rotor purge is required.

In another embodiment, the supply tube 60 may extend downward from the impingement baffle cavity 30 to the CMC metal boundary member 50. In other embodiments, instead of using the supply tube 60 to form the plenum, the mounting member 70 includes a flow path or opening (not shown) for receiving the purge air 120 of the rotor. In another embodiment, the CMC metal boundary member 50 may not be pressurized.

一実施形態では、ＣＭＣ金属境界部材は、取付け部材を含む。例えば、図１及び図２に示すように、ＣＭＣ金属境界部材５０は、取付け部材７０を含む。取付け部材７０は、特に限定されないが、取付け部材７０をＣＭＣ金属境界部材５０内にタップ加工する、ナットを用いて取付け部材７０をＣＭＣ金属境界部材５０に固定する、インサートを用いて取付け部材７０をＣＭＣ金属境界部材５０に固定するなど、適切な手段によって、ＣＭＣ金属境界部材５０に取り付けることができる。取付け部材７０の材料は、特に限定されないが、金属、金属合金及びこれらの組合せを含んでおり、例えば、合金は、ニッケル基超合金、コバルト基超合金及びこれらの組合せを含む。   In one embodiment, the CMC metal boundary member includes an attachment member.

In one embodiment, the impingement baffle cavity 30 includes an opening (not shown) for receiving the attachment member, which may be threaded to receive the attachment member 70. In other embodiments, the attachment member 70 may not be secured within the impingement baffle cavity 30, but instead steadily holding the attachment member 70 in place at the second end 16 of the CMC component 10. A nut or other locking member can be used to do this.

一実施形態では、ＣＭＣ金属境界部材は、静止シールをＣＭＣ部品に連結するための表面を提供する。例えば、図１及び図２に示すように、ＣＭＣ金属境界部材５０は、静止シール４０をＣＭＣ部品１０に連結するための表面を与える。静止シール４０は、特に限定されないが、ろう付け及び溶接のような適切な連結手段によって、ＣＭＣ金属境界部材５０に取り付けることができる。ＣＭＣ金属境界部材５０と静止シール４０の間の継手４６は、図１及び図２に示してある。一実施形態では、静止シール４０はハニカムシールである。静止シール４０の材料は、特に限定されないが、金属、金属合金及びこれらの組合せから選択することができ、例えば、合金は、ニッケル基超合金、コバルト基超合金及びこれらの組合せを含む。静止シール４０は、ガスタービン内で回転シール１１０に隣接する。   In one embodiment, the CMC metal boundary member provides a surface for connecting the stationary seal to the CMC component. For example, as shown in FIGS. 1 and 2, the CMC metal boundary member 50 provides a surface for connecting the stationary seal 40 to the CMC component 10. The stationary seal 40 can be attached to the CMC metal boundary member 50 by suitable connection means such as, but not limited to, brazing and welding. The joint 46 between the CMC metal boundary member 50 and the stationary seal 40 is shown in FIGS. In one embodiment, stationary seal 40 is a honeycomb seal. The material of the stationary seal 40 is not particularly limited, but can be selected from metals, metal alloys, and combinations thereof, for example, alloys include nickel-base superalloys, cobalt-base superalloys, and combinations thereof.
