Ib txhia hais tias nws yog ib daim qauv ntawm F-22, lwm tus hais tias nws stealth yog ib tug neeg pluag heev uas yuav suav hais tias yog ib tug thib plaub - tiam fighter. Tab sis tej zaum koj yuav tsis paub tias lub dav hlau Lavxias teb sab fighter nrog nws pixelated camouflage hides ib tug tumultuous industrial keeb kwm. Lub Ib Hlis 29, 2010, Komsomolsk-nyob rau-Amur. Ib lub dav hlau zoo li lub dav hlau sib ntaus sib tua tau tawg los ntawm qhov txias txias thiab ua tiav nws lub dav hlau maiden. Cov Russians tau tos yuav luag nees nkaum xyoo rau hnub no. Cov neeg Amelikas 'F-22 tau ua haujlwm ntev, thiab F-35 tau nrawm nws cov davhlau sim. Russia, txawm li cas los xij, tsuas yog xa tus qauv no, hu ua T-50, mus rau saum huab cua. Tom qab ntawd, nws tau hloov lub npe Su-57. Tab sis txawm niaj hnub no, qhov kev tsis sib haum xeeb nyob ib puag ncig lub dav hlau fighter no yeej tsis tso tseg. Ib qho qub txeeg qub teg ntawm Soviet, zaj dab neeg ntawm ob qho tib si prototypes pib thaum xyoo 1980s. Lub sijhawm ntawd, Tebchaws Meskas tab tom tsim "Advanced Tactical Fighter Jets," thiab Soviet Union tsis nyob ib leeg. Lawv tau tsim ib qho kev pab cuam hu ua PAK FA, lub hom phiaj los tsim lawv tus kheej tom ntej no - tiam fighter dav hlau. Ob yam khoom tseem ceeb yog MiG-1.44, uas muaj lub teeb tsa canard thiab ntxaib ntsug tails, thiab Su-47 "Berkut," uas ua haujlwm siab heev rau pem hauv ntej- swept tis. Dab tsi yog qhov tshwm sim rau MiG-1.44 thiab Su-47? Tsuas yog ib qho qauv ntawm txhua tus tau tsim. Nws tsis yog tias lawv tsis xav tsim lawv; txhua tus muaj nws tus kheej qhov tsis zoo thiab tsuas yog tsis ua raws li cov qauv ntawm qib tsib - tiam neeg sib ntaus sib tua. Lub cev qhuav dej ntawm lub Soviet Union tsuas yog exacerbated qhov teeb meem. Thaum lub F-22 twb tau tsim ntau lawm, Russia tsuas yog saib tsis muaj zog. Ib qho kev hloov pauv tuaj rau xyoo 2000 thaum Is Nrias teb los ze lawv. Ib lub teb chaws tsis muaj nyiaj tab sis muaj cov cuab yeej technology; lwm tus muaj nyiaj tab sis tsis muaj thev naus laus zis. Lawv tau txais kev pom zoo sai sai rau kev sib koom ua ke tsim lub thib tsib- tiam neeg tua rog. Nyob rau hauv 2001, Russia officially restarted qhov project. Sukhoi yeej tawm tsam Mikoyan, vam khom nws lub zog tsim khoom. Muaj ob lub tswv yim sib tw thaum lub sijhawm. Mikoyan muab E{114}}721, hais txog nws tus nqi qis thiab yooj yim ntawm kev tsim khoom. Sukhoi muab T-50, khav theeb ua tau zoo tshaj thiab thev naus laus zis. Thaum kawg, Sukhoi yeej. Vim li cas? Thaum kawg, nws tag nrho los ntawm lub zog ntawm kev tsim khoom. Lub Su-27 series tau raug xa tawm hauv cov lej loj, nrog cov qauv sib txawv ntau dua li MiG-29. Kev muag khoom ntau txhais tau tias muaj txiaj ntsig ntau dua, thiab cov txiaj ntsig ntau dua txhais tau tias nyiaj rau R & D, tsim pab pawg, thiab sib sau ua ke. Qhov no yog qhov yooj yim logic ntawm kev tsim khoom: ntau lawm ntim ua rau tsub zuj zuj, thiab tsub zuj zuj coj mus rau breakthroughs. Ntau xyoo tom qab ntawd, T-50 tau hloov lub npe Su-57. Tab sis lub npe hloov pauv tau coj nws cov teeb meem. Qhov tsis muaj peev xwm ua kom haum lub cav tau qhia txog qhov teeb meem tseem ceeb: ib qho ntawm Su-57 qhov tsis haum loj tshaj plaws yog nws lub cav tsis zoo. Txhua tus uas muaj kev txawj ntse tuaj yeem pom qhov no yog qhov tsis txaus ntseeg rau kev nyiag. Vim li cas qhov no tsim? Tsis yog vim lawv tsis xav zais nws, tab sis vim lawv ua tsis tau. Lub Su-57 lub cav thawj zaug nrhiav tsis tau, yog li lawv yuav tsum siv tib lub AL-41F1 (tseem hu ua Khoom 117) raws li Su{141}}35. Lub cav no nws tus kheej tsis phem, tab sis nws loj heev. Thaum qhov project tau pib, qhov loj me no tsis tau txiav txim siab, ua rau rov qab hloov kho thiab hloov kho, thaum kawg tawm ntawm lub nozzle nthuav tawm. Qhov no qhia txog qhov teeb meem ntev - sawv cev hauv kev tsim khoom hauv Lavxias: ib qho kev faib khoom sib cais. Cav thiab airframes yog ob lub tshuab sib cais, thiab lawv cov kev sib koom ua ke tau poob qis tom qab lub cev qhuav dej ntawm Soviet Union. Ib qho kev tivthaiv zoo tsis tuaj yeem haum rau lwm qhov zoo hauv, thaum kawg cuam tshuam qhov kev ua tau zoo tag nrho. Qhov xov xwm zoo yog tias, raws li Lavxias xov xwm tshaj tawm, cov khoom xa tawm tshiab Su{148}}57s yuav pib nruab nrog lub cav AL-51F1 thaum kawg ntawm 2023. Lub cav tshiab no siv lub tshuab serrated zoo ib yam li F{151}}35, ua rau lub nkoj supersonic tsis muaj kev kos npe tom qab, thiab tseem ceeb heev. Tab sis cov lus nug tseem: muaj peev xwm ua tau li ntawd? Thiab nws lub peev xwm stealth zoo npaum li cas? Ntau tus hais tias Su-57 lub stealth yog neeg pluag, qhov zoo tshaj plaws plaub tiam{155}}tiam- ntxiv rau. Qhov no muaj qee qhov txiaj ntsig, tab sis nws tsis meej. Ua ntej, nws qhov tsis muaj zog: nthuav tawm lub cav nozzles, lub fuselage tsis sib xws, raug ntsia hlau, thiab ncaj nraim - los ntawm huab cua nkag… cov no muaj tseeb cuam tshuam rau stealth. Piv rau F-22's tag nrho{183}}nyob ib puag ncig kev nyiag, Su-57 yog qib hauv qab. Tab sis nws nyob ntawm qhov nws tau muab piv rau. Cov ntaub ntawv pov thawj Lavxias pom tau tias Su-57's radar cross-section yog nruab nrab ntawm 0.1 thiab 1 square meter, tsuas yog ib feem peb caug ntawm Su-27's. Qee cov netizens siv 3D qauv simulations (tsis quav ntsej radar-absorbing cov ntaub ntawv) thiab pom tias Su-57's radar cross-section nyob rau hauv ib tug 120-degree vojvoog yog kwv yees li 0.48 square meters, thaum lub F-35's yog 0.06 square meters nyob rau hauv tib yam. Yog tias radar-absorbing cov ntaub ntawv suav nrog, tus nqi tiag tiag yuav qis dua. Niaj hnub nimno radar muaj peev xwm tshawb nrhiav tau txwv rau cov hom phiaj me dua 1 square meter, yog li Su-57 tseem tuaj yeem suav tias yog lub dav hlau stealth. Lwm nthuav nthuav dav: pixel camouflage. Lub Su-57 cov qauv xim tshwj xeeb tsis yog rau kev zoo nkauj xwb. Qhov no pixelated style blurs lub fuselage ciam teb thaum lub sij hawm high-ceev davhlau, cia lub dav hlau sib tov zoo rau saum ntuj. Qhov no yog ib daim ntawv ntawm "visual stealth" los them rau qhov tsis txaus radar stealth, tus yam ntxwv ntawm Russia. Lavxias teb sab logic: maneuverability ua ntej. Vim li cas Su-57 tsis ua raws li F-22 tus qauv thiab ua kom muaj kev zais ntau tshaj plaws? Nws tsis yog ib qho teeb meem ntawm kev siv technology tsis txaus, tab sis yog ib txoj hauv kev sib txawv. Cov neeg Lavxias txoj kev nkag siab ntawm cov neeg tua rog thib tsib yog qhov stealth yuav tsum muab txoj hauv kev rau maneuverability. Yog tias sniper tuaj yeem tua tus yeeb ncuab ntawm ib mais deb nrog kev txhaj tshuaj ib zaug, lawv puas yuav tsum tau nruab nrog rab yaj phom thiab xyaum ntaus bayonet? Nyob rau hauv lawv cov lus, F-22 tsis muaj peev xwm tawm tsam hauv av, thiab F-35 qhov kev ua tau zoo dhau lawm, yog li lawv tsuas yog ua ke qhov zoo ntawm ob qho tib si. Ib qho hais ncaj qha: 57=22 + 35. Tus qauv tsim, Su-57 kom meej meej ua raws qhov dav-spaced twin-engine layout tau txais los ntawm Su-27. Qhov kev tsim no muaj kev ua haujlwm zoo, tab sis lub fuselage tsis sib xws cuam tshuam rau stealth. Sab nraud-canted ntxaib ntsug tails yog positioned rau pem hauv ntej, thiab tag nrho ntsug tus Tsov tus tw yog ib tug movable tswj nto-qhov no zoo li F-22 tus neeg sib tw, YF-23. Nyob rau hauv luv luv, lub Su-57 tsis txi aerodynamic kev ua tau zoo rau stealth. High-altitude, high-speed, thiab super-maneuverability-cov kev cai qub ntawm Soviet aircraft tau khaws cia. Cov avionics thaum kawg tau ncaim ntawm lub "clock shop" style cockpit ntawm yav dhau los Soviet fighters, uas yog jokingly hu ua " moos khw" - tag nrho ntawm analog instruments. Lub Su-57 thaum kawg tau tig nws txoj hmoov zoo nyob ib puag ncig. Lub cockpit nta ob lub 38cm multi-function LCD cov ntxaij vab tshaus thiab lub kaum sab xis HUD. Cov kws tsav dav hlau tau nruab nrog lub kaus mom hlau-mounted qhia uas siv cov tub ntxhais kawm taug qab los txhim kho kev paub txog xwm txheej. Lub radar system, hu ua N036 "Squirrel," muaj tsib lub radars: lub ntsiab radar hauv lub qhov ntswg, sab radars ntawm ob sab ntawm lub qhov ntswg, thiab L-band radars ntawm tis. Cov kab ke no, ua ke nrog ob lub khoos phis tawj onboard, tuaj yeem ntes cov hom phiaj ntawm 400 mais deb, ib txhij taug qab 30 lub hom phiaj, thiab koom nrog 8 ntawm lawv. Nws tuaj yeem hais tias Su-57 suav nrog Russia cov thev naus laus zis thiab cov ntaub ntawv thev naus laus zis, ua rau nws yog lub dav hlau ntse tshaj plaws uas lawv tuaj yeem tsim. Is Nrias teb raug ntxias nrog cov lus cog tseg, tab sis thaum kawg xaiv tawm mus. Russia tau cog lus rau Is Nrias teb kom muaj txiaj ntsig zoo: ntau qhov kev txhim kho raws li Is Nrias teb cov cai, cov ntawv tso cai tsim khoom, ob lub rooj ntau lawm kab hauv Is Nrias teb, thiab tseem muaj peev xwm xa tawm. Is Nrias teb tau txaus siab heev thiab tau tshaj tawm txog $ 30 nphom kev nqis peev. Tom qab nws lub dav hlau dav hlau xyoo 2010, ob tog tau pom tias yuav tsim tau 1,000 lub dav hlau nyob rau 40 xyoo tom ntej-200 txhua rau kev siv hauv tsev thiab 600 rau kev xa tawm. Tab sis qhov tseeb yog hnyav. Hauv xyoo 2011, cov kab nrib pleb tau tshwm sim hauv lub fuselage ntawm ob lub qauv tom qab ua qauv qhia dav hlau raws li 5G txwv. Lub zog thiab cov khoom siv lub neej ntev-qhov tseem ceeb tshaj plaws hauv kev tsim khoom-tau rov nthuav tawm. Thawj theem ntawm kev sim tsis tau ua tiav kom txog rau thaum 2014. Russia pom tau tias nws tsis tuaj yeem tuav ib lub rooj zaum ib leeg, cia nyob ib leeg ob lub rooj zaum. Hauv 2018, Is Nrias teb tau thim tawm hauv kev poob siab thiab txiav txim siab los tsim nws tus kheej AMCA. Txawm li cas los xij, tom qab ntawv tshaj tawm qhia tias Is Nrias teb tseem xav yuav 40 Su-57s raws li "kev hloov pauv" ntsuas. Txog niaj hnub no, tsuas yog ob peb lub kaum os Su-57 tau tsim. Lub F-35 tau tshaj ib txhiab, thiab txawm tias J-20, uas muaj lub davhlau tom qab, muaj tsawg kawg yog 350. Qhov sib txawv no tsis tuaj yeem piav qhia los ntawm kev siv tshuab ib leeg.
