Tom qab J-20 fighter dav hlau tau nruab nrog lub cav turbofan 10C thiab paub txog kev tsim tawm hauv tebchaws, thaum nws yuav nruab nrog lub cav WS15 yuav dhau los ua qhov tseem ceeb ntawm txhua tus neeg mloog. Cov xov xwm tshiab kawg yog tias WS-15 tau raug tsim tawm ntau, thiab J-20 tab tom yuav ua tiav ntau lawm hauv lub xeev tiav.

Ntawm 3rd China Aviation Investment Summit thiab 7th Aviation Innovation thiab Entrepreneurship Competition Finals tau tuav tsis ntev los no, cov kws tshaj lij tau tshaj tawm xov xwm zoo siab tias WS-15 tau tawg los ntawm kev nyuaj thiab ua tiav ntau lawm. Tseem tsis tau muaj teeb meem kev lag luam hauv kev mus rau hauv cov khoom lag luam hauv lub xeev ua tiav ua ntej 2025.
[Kev txwv tsis pub tawm tsam Tebchaws Meskas yog qhov muaj zog tshaj plaws]
Lub cav WS-15 yog lub tshuab ua tub rog thib plaub uas tsim los ntawm Tuam Tshoj. Nws cov qib kev kawm ncaj qha piv rau American F-119 turbofan engine. Lub tom kawg yog lub cav ntawm F-22 fighter dav hlau, nrog ib tug afterburner thrust ze rau 17 tons. Nrog lub zog thrust ntawm lub cav, F-22 fighter dav hlau tau ua tiav supersonic cruise muaj peev xwm, thiab nws cov kev sib ntaus sib tua tau zoo heev.

F-22 fighter nrog F-119 cav
Kev ua tau zoo ntawm F-119 lub cav yog los ntawm cov thev naus laus zis siab, cov ntaub ntawv thiab cov txheej txheem uas nws siv, suav nrog peb-dimensional computational fluid dynamics, ib leeg siv lead ua cov ntaub ntawv, ib qho turbine disks, high-strength nplaim-retardant titanium alloys, a tiam tshiab ntawm hmoov superalloys, thiab advanced manufacturing technologies thiab craftsmanship thiab lwm yam.
Vim yog kev siv cov thev naus laus zis tshiab, kev ua haujlwm ntawm F-119 lub cav tau txhim kho zoo heev. Qhov piv txwv pom tseeb tshaj plaws yog tias qhov kub thiab txias nyob rau hauv pem hauv ntej ntawm nws lub turbine yog siab li 1900K, uas yog ze li ntawm 300K siab dua li ntawm lub cav F-110. Nws tuaj yeem hais tias qhov ntsuas no tau mus txog cov khoom siv thiab qhov txwv ntawm cov txheej txheem txias. Lub thrust ntawm niaj hnub cav yog los ntawm lub zog tsim los ntawm thermal expansion ntawm huab cua, yog li lub thrust ntawm lub cav yog zoo correlated nrog qhov kub thiab txias qhov sib txawv ntawm qhov nqus thiab pa. Rau cov niaj hnub aero-engines, txoj hauv kev ncaj qha tshaj plaws los ua kom muaj zog yog nce qhov kub thiab txias ua ntej lub turbine. Nyob rau hauv cov xwm txheej ntawm qee qhov kev tawm tsam tom qab, qhov kub thiab txias ua ntej lub turbine yuav pab ua kom lub zog thrust tsis muaj afterburner, uas yog ib qho ntawm cov xwm txheej tseem ceeb rau cov neeg tua rog kom muaj peev xwm caij nkoj ntawm supersonic.
[Nws yog ib qho nyuaj heev kom tau txais F119, thiab nws tseem ua rau muaj kev tsis ntseeg]
Vim lub tshuab nyuaj heev ntawm F-119 turbofan engine, txawm tias Tebchaws Meskas siv ze li 20 xyoo los ua tiav nws thiab ua tiav ntau lawm.
Yog li ntawd, thaum peb txiav txim siab los ntsuas lub WS-15 tawm tsam F-119 turbofan cav, nws ua rau muaj kev sib cav hauv kev lag luam. Tab sis tom qab kev sib tham, cov kws tshaj lij tsuas tuaj yeem lav qhov kev ua tau zoo ntawm WS-15 los ntawm kev ua piv txwv tawm tsam F-119, kom J-20 tuaj yeem muaj peev xwm tsav nkoj supersonic thiab ua tiav lub hom phiaj ntawm kev sib tw nrog F{{ 5}} dav hlau fighter.
Txhawm rau kom ua tiav lub hom phiaj no, Tuam Tshoj lub tshuab aero-engine pem hauv ntej tau ua haujlwm nyuaj thiab tau tshawb fawb mus ntev. Noj deformed superalloys ua piv txwv, F-119 turbofan cav siv txog li 40 feem pua titanium alloy thiab muaj kev khiav hauj lwm kub ntawm 600 degrees. Qhov kev faib ua feem ntawm domestic turbofan -10 titanium alloy tsuas yog kwv yees li 20 feem pua, thiab qhov kub thiab txias ua haujlwm yog ze rau 500 degrees. Muaj qhov sib txawv loj ntawm ob. Los ntawm kev ua haujlwm hnyav, cov kws tshaj lij ntawm cov koom haum muaj feem cuam tshuam tau tsim ib tiam tshiab ntawm domestic deformed superalloy, uas tau ua tiav rau WS-15, tshem tawm txoj hauv kev rau WS-15 kom dhau F-119 .

Tom qab lub J-20 fighter dav hlau tau teeb tsa nrog WS-15 lub cav, nws yuav muaj peev xwm caij nkoj zoo tshaj plaws, thiab tam sim no tsuas yog lub dav hlau F-22 fighter muaj peev xwm.

Lub sij hawm ntev supersonic davhlau tsis muaj afterburner tuaj yeem tau txais txiaj ntsig zoo heev
Vim hais tias J-20 fighter avionics system yog superior rau F-22 fighter, piv txwv li, lub J-20 fighter yog nruab nrog ib tug faib optical aperture system, thiab nws muaj peev xwm mus ntes stealth lub hom phiaj. yog zoo dua qhov F-22. Yog tias nws muaj peev xwm caij nkoj supersonic, nws yuav muaj txiaj ntsig zoo hauv kev sib ntaus sib tua huab cua.
Txhawm rau koom tes nrog kev txhim kho kev ua tau zoo, J-20 kuj tau ua kom zoo rau kev tsim qauv. Piv txwv li, nws lub cockpit tau ntxiv ib qho pom tseeb bulge los sau lub davhlau tsis zoo siab cheeb tsam, yog li txo cov davhlau tsis kam, tshwj xeeb tshaj yog cov tsis kam nyob rau hauv supersonic thiab transonic speeds. Tom qab kev txhim kho zoo li no, lub peev xwm ntawm kev caij nkoj supersonic ntawm J-20 tau txhim kho zoo, ntxiv kev txhim kho kev ua haujlwm ntawm lub dav hlau nyob rau hauv cov xwm txheej supersonic.

Piv nrog rau F-22 hauv xyoo 1990, J-20 muaj qhov zoo dua qub hauv cov tshuab hluav taws xob
[Kev txhim kho aviation hauv tsev yog nyob rau hauv nws cov theem thaum ntxov, ushering nyob rau hauv ib puas paj blooming]
Los ntawm qhov kev xav tam sim no, txoj kev vam meej ntawm WS-15 tsis yog tsuas yog paub txog kev ua tiav ntawm J-20 fighter dav hlau, tab sis kuj ua tiav cov kev ua tau zoo uas tuaj yeem siv los txhim kho cov tshuab uas twb muaj lawm thiab taug kev rau txoj kev loj hlob ntawm cov tiam tom ntej ntawm kev ua haujlwm siab propulsion systems.
Nws tau tshaj tawm tias turbofan 10 thiab turbofan 20 lub cav siv cov tshuab hluav taws xob sib hloov tshuab, uas yog ib qho ntawm cov yam ntxwv ntawm plaub tiam turbofan xyaw. Txo shafting ntev thiab hnyav vim turbine alignment, txo lub cav hnyav. Los ntawm qhov kev pom no, theem kev kawm ntawm domestic turbofan 10 thiab turbofan 20 lub cav yog zoo dua li ntawm F-110 thiab CMF-56 cav.
Nyob rau hauv cov nqe lus ntawm cov tiam tom ntej high-performance propulsion system, nws muaj ntau dua thrust thiab ib tug ntau dua thrust-rau-hnyav piv, thiab muaj ntau dua yuav tsum tau rau tsim, cov ntaub ntawv, manufacturing, thiab craftsmanship. Peb tuaj yeem txhim kho txuas ntxiv raws li WS-15 qhov project thiab muab ib tiam tshiab ntawm domestic Tsim kom muaj txiaj ntsig zoo rau kev tsim cov tshuab ua haujlwm siab.
Yav tom ntej, AECC tseem yuav txhim kho WS-15 nrog rau cov txiaj ntsig ntawm kev txhim kho lub cim tshiab ntawm lub cav. Ntawm qhov tod tes, WS-15 lub cav tuaj yeem txhim kho, thiab ntawm qhov tod tes, cov thev naus laus zis ntawm lub cav tshiab kuj tuaj yeem txheeb xyuas tau.
Lub ntiaj teb sab nraud kwv yees tias Tuam Tshoj lub dav hlau tiam 6 tiam yuav txuas ntxiv ua raws li J-20 cov tswv yim txhim kho, thawj zaug siv lub cav WS-15 lossis ib qho kev txhim kho los ntsuas lub dav hlau tsim, thiab txawm siv lub WS-15 txhim kho lub cav nyob rau theem pib. Nyob rau hauv txoj kev no, lub sijhawm tuaj yeem yuav rau kev txhim kho ntawm lub tshuab thib tsib. Tom qab lub thib tsib-tiam engine matures, lub thib rau-tiam fighter yuav tau nruab kom nws ua hauj lwm tag nrho. Kev tshawb fawb thiab kev loj hlob ntawm ib tiam tshiab ntawm fighter dav hlau nyob nruab nrab ntawm Tuam Tshoj thiab lub tebchaws United States sawv ntawm tib txoj kab pib thawj zaug, thiab cov cuab yeej cuab tam thaum kawg yeej sib npaug.
