Lub cav aviation yog "lub plawv" ntawm lub dav hlau. Lub cav ntawm cov neeg caij dav hlau dav hlau tsom rau kev nyab xeeb thiab kev ntseeg siab, thaum lub cav tub rog tseem ua kom muaj zog ntau dua ntawm lub hauv paus no, nrog rau qhov siab tshaj plaws thaum lub tshuab hluav taws xob qhib. Nws tuaj yeem pom tau tias cov neeg ua si muaj zog tshaj plaws hauv kev lag luam aviation cav yuav tsum yog cov tub rog aviation xyaw, thiab cov cav tub rog tau suav tias yog qhov tseem ceeb ntawm tib neeg thev naus laus zis. Lub teb chaws uas muaj peev xwm ntawm R & D, tsim thiab tsim cov tshuab aerospace feem ntau tsis yooj yim xa tawm lawv tus kheej thev naus laus zis. Lawv tsuas yog xa tawm cov tshuab ua tiav, thiab qee qhov tseem yuav tsum tau xa rov qab mus rau lub tebchaws ntawm keeb kwm rau kev saib xyuas. Nws nyuaj npaum li cas los tsim lub tshuab dav hlau? Qhov nyuaj ntawm nws qhov kev tsim khoom yog nyob rau hauv nws cov qauv complex thiab high-precision yuav tsum, uas muaj ntau yam xws li cov khoom xaiv, tsim, manufacturing, tswj system thiab nruj me ntsis soj ntsuam. Cia wb mus saib ua ke.
Yooj yim rau luam thiab disassemble
Qhov nyuaj ntawm kev tsim cov tshuab aeroengines yog thawj zaug pom nyob rau hauv qhov nyuaj ntawm kev luam thiab dismantling. Cov tsos ntawm lub tsheb lossis lub dav hlau tuaj yeem theej los ntawm kev rov qab daim ntawv qhia. Needless hais, tsheb kuj yooj yim rau luam. Kuj tseem muaj cov ntawv luam tawm dav hlau, xws li Tu-160 thiab B-1B bombers, tab sis kev luam ntawm lub cav yog yooj yim ua tsis tau yam tsis muaj kev cuam tshuam ntawm kev kos duab. Piv txwv li, CFM-56 series cav, lub tshuab tseem ceeb tam sim no siv rau ntawm Boeing 737 tus neeg caij dav hlau, tau tsim ntau dua 20,000 units los ntawm nws thawj zaug ua haujlwm xyoo 1974 txog hnub no. Nws yog siv nyob rau hauv yuav luag tag nrho ib leeg-aisle neeg nrog caij dav hlau tsuas yog tsim los ntawm Boeing thiab Airbus.

Thaum dismantling CFM-56, koj yuav pom tias lub cav cav yog npog nrog ntau lub qhov me me txog qhov loj ntawm tus ntiv tes. Yog tsis muaj qhov chaw kos duab, nws tsis tuaj yeem luam lawv. Thaum lub qhov cua yog punched nyob rau hauv tsis ncaj ncees lawm txoj hauj lwm, nws yuav ncaj qha cuam tshuam lub tshav kub dissipation ntawm cov hniav, thiab tag nrho cov kev ua tau zoo ntawm lub replica yuav txo. Kev vam khom rau lub hauv paus ntawm CFM-56, GE tau tsim cov cav uas tuaj yeem siv rau ntau yam qauv dav hlau, ncaj qha sib tw nrog Pratt & Whitney.
Cov ntaub ntawv nyuaj rau kev tsim khoom
Lub cav aviation yog qhov yooj yim heev. Siv lub tshuab CFM-56 classic ua piv txwv, suav nrog lub tshuab hluav taws xob qis, cuaj-theem siab-siab compressor, thawj-theem high-pressure turbine, plaub-theem qis-siab turbine, thiab ib qho annular combustion chamber nyob nruab nrab. Txawm li cas los xij, cov qauv no muaj qhov sib txawv ntawm qhov kub thiab txias ua haujlwm, uas txhais tau hais tias cov khoom siv sib txawv. Siv turbine hniav ua piv txwv. Qhov chaw ua haujlwm yog ntau txhiab degrees Celsius, kaum tawm txhiab tus kiv puag ncig ib feeb, thiab lawv tau ua los ntawm kev sib xyaw ntawm ntau cov hlau uas sib txawv.

Vim hais tias cov hniav nyob ze ntawm lub combustion chamber yuav raug kub siab dua thiab cov ntaub ntawv yog siv los tiv taus kub, cov proportions ntawm tsawg hlau ntsiab yog txawv. Yog tias txhua yam khoom siv kub-resistant tib yam siv, chav tsev nqi yuav siab thiab kev lag luam yuav tsis zoo. Rau kev lag luam ua lag luam pej xeem neeg caij dav hlau cav, nws yog qhov zoo tshaj kom pheej yig thiab siv tau yooj yim.
Nyob rau hauv tib txoj kev, ntxiv rau turbine hniav, cov ntaub ntawv siv nyob rau hauv txhua lub cav tivthaiv kuj txawv. Lub CFM-56 cav turbine siv los ntawm Boeing 737 yog ua los ntawm high-temperature alloy, thiab qee qhov chaw siv cov khoom sib xyaw. Tam sim no nrov dua yog resin-based composite khoom. Pratt & Whitney's F-119 sab nraud ducted receiver siv cov khoom no, uas tuaj yeem tiv taus qhov kub thiab txias ntawm 400 degrees Celsius, thiab tus nqi kuj tuaj yeem tswj tau.

High precision ua
Yog tias koj muaj cov khoom siv siab heev thiab cov duab kos, nws tsis tau txhais hais tias koj tuaj yeem tsim lub tshuab aero zoo heev, vim tias kev siv tshuab yog qhov teeb meem kawg. Cov kiv cua ntawm CFM-56 cav aeroengine tsuas yog 1.55 meters hauv txoj kab uas hla thiab 2.5 meters ntev. Nws yuav tsum tsim 86 kN ntawm thrust nyob rau hauv xws li ib tug me me qhov chaw. Koj tuaj yeem xav txog yuav ua li cas nyuaj rau kev siv tshuab ua haujlwm.
Los ntawm ib qho kev xav me me, siv lub ntsiab lus tseem ceeb tam sim no ib leeg siv lead ua turbine hniav ua piv txwv, cov txheej txheem casting precision yuav tsum muaj qhov yuam kev ntawm 0.1 hli, txhawm rau xyuas kom meej tias txhua cov hniav tuaj yeem ua haujlwm ib txwm. Yuav kom ua tiav ntau yam ntaub ntawv alloy ua ke, koj yuav tsum paub txog kev ua haujlwm thiab cov txheej txheem vuam ntawm cov hlau kub kub. Nyob rau tib lub sijhawm, lub cav rotor thiab cov hniav yog khiav ntawm kev kub ceev thaum lub sijhawm ua haujlwm. Kev siv tes ua haujlwm tsis txaus txhais tau hais tias lub cav hnav tawm sai sai thiab muaj lub neej ua haujlwm luv luv, uas cuam tshuam ncaj qha rau kev lag luam.

Cov kev xav tau siab ntawm thev naus laus zis kuj txhawb kev ua haujlwm ntawm aero-engine kev ua haujlwm. Siv cov hniav ua piv txwv, GE tau tsim cov hniav sib txuas uas tsis muaj pob tw. Muaj ib qho software ua los ntawm cov khoom siv tshwj xeeb ntawm sab nraud ntawm lub cav hniav, uas tuaj yeem siv tau thaum cov hniav ua haujlwm. Seamlessly txuas nrog lub nplhaib txheej txheej los txhim kho lub cav efficiency. Xws li cov ntaub ntawv mos muaj cov kev xav tau siab heev rau kev siv tshuab. Lawv yuav tsum tsis tsuas yog tswj kev ruaj ntseg, tab sis kuj yog kev lag luam thiab yuav tsum tau saib xyuas me ntsis. Txwv tsis pub, thaum txhim kho lub cav efficiency, nws tseem yuav ua rau kom lub nra ntawm cov neeg ua haujlwm hauv av, thiab kev lag luam kev lag luam yuav tsis pom tseeb txaus.
Yuav kom suav tau, los ntawm qhov kev xav ntawm kev rov qab soj ntsuam, cov khoom siv thiab kev siv thev naus laus zis, lub tshuab aero yuav tsum tau hais tias yog lub hauv paus ntawm kev lag luam engineering thiab lub cim ntawm lub teb chaws txoj kev tshawb fawb thiab thev naus laus zis.
Raws li WS-10 "Taihang" cav, kuv lub teb chaws tau tsim nws tus kheej tsim lub WS-20 high-bypass-ratio, high-thrust turbofan cav rau kev siv tub rog thiab pej xeem, uas yog nruab nrog Y -20 lub dav hlau thauj tswv yim. Peb lub teb chaws tseem tab tom tsim Yangtze-1000A high-bypass ratio turbofan cav rau kev teeb tsa ntawm C-919 civil aircraft, thiab npaj yuav sib sau ua ke thiab tsim lub ntiaj teb-chav kawm LEAP-X "Safran" cav domestically . Nyob rau tib lub sijhawm, tiam tom ntej ntawm kev sib tw loj bypass piv xyaw nrog lub zog ntawm 200 mus rau 400 kN kuj tau tsim. Cov haujlwm no txhua tus qhia tau hais tias lub sijhawm "blowout" ntawm Tuam Tshoj tus loj bypass piv xyaw yog los.
