Irkut twv cov neeg loj heev. MS-21 qhia hauv Irkutsk
Lavxias Thawj Fwm Tsav Tebchaws Dmitry Medvedev nthuav tawm MC-21-300, Russia thawj tus neeg caij dav hlau loj hauv ib lub hlis twg ntawm ib puas xyoo, nrog rau cov neeg Lavxias xav sib tw nrog lub ntiaj teb nrov tshaj plaws Airbus A320 thiab Boeing 737. Pyotr Butovsky
Thaum Lub Rau Hli 8, 2016, nyob deb Irkutsk ntawm Lake Baikal, hauv hangar ntawm IAZ tsob nroj (Irkutsk Aviation Plant), lub dav hlau sib txuas lus tshiab MS-21-300 tau nthuav tawm thawj zaug, uas Irkut Corporation sib tw Airbus A320 thiab Boeing 737. MS-21-300 - yooj yim, 163-lub rooj version ntawm lub neej yav tom ntej aircraft ntawm MS-21 tsev neeg. Lub dav hlau yuav tsum tawm ntawm nws lub dav hlau dav hlau thaum ntxov xyoo tom ntej.
Lub ceremony tau koom nrog Prime Minister ntawm Lavxias teb sab tsoom fwv Dmitry Medvedev, hais txog qhov kev cia siab uas tsoom fwv Lavxias tso rau lub dav hlau no. MS-21 yog ib lub dav hlau niaj hnub tshaj plaws hauv ntiaj teb, cov neeg caij dav hlau ntawm lub xyoo pua 21st. Peb zoo siab heev uas tau tsim nyob rau hauv peb lub teb chaws. Medvedev cais cov neeg xa khoom txawv teb chaws koom nrog hauv MS-XNUMX qhov project. Nws yog ib qho tseem ceeb heev rau peb tias, ntxiv rau peb cov tuam txhab dav hlau zoo tshaj plaws, ntau lub tuam txhab txawv teb chaws tau koom nrog hauv qhov project. Peb ua tsaug rau cov neeg lag luam uas ua haujlwm hauv tebchaws Russia, uas tseem nyob hauv lub tsev niaj hnub no thiab cov uas tau ua haujlwm zoo nrog peb lub tebchaws.
MS-21 yuav tsum yog cov khoom tawg. Cov neeg Lavxias nkag siab tias ntxiv lwm txoj haujlwm zoo sib xws ntawm Airbus 320 thiab Boeing 737 (nrog rau Suav C919 tshiab) yuav tsis muaj txoj hauv kev ua tiav. Rau MC-21 kom ua tiav, nws yuav tsum tau pom zoo tshaj qhov kev sib tw. Cov ambitions zoo heev twb pom nyob rau hauv lub npe ntawm lub aircraft: MS-21 yog lub Lavxias teb sab dav hlau ntev ntawm lub xyoo pua 21st. Qhov tseeb, lo lus Cyrillic MS yuav tsum tau muab txhais ua MS, thiab qhov ntawd yog li cas nws tau hu ua thawj cov ntawv tshaj tawm txawv teb chaws, tab sis Irkut sai sai muab cov khoom hauv kev txiav txim thiab txiav txim siab thoob ntiaj teb kev tsim lawv txoj haujlwm ua MS-21.
Lub hom phiaj tau teeb tsa kom pom tseeb: tus nqi khiav haujlwm ncaj qha ntawm MC-21 lub dav hlau yuav tsum yog 12-15% qis dua cov dav hlau niaj hnub zoo tshaj plaws ntawm chav kawm no (Airbus A320 yog coj los ua piv txwv), thaum noj roj yog 24%. hauv qab no. Piv nrog rau kev hloov kho A320neo, MC-1000 yuav tsum haus 1852% roj tsawg ntawm txoj kev 21 nautical mais (8 km), nrog rau 5% qis dua cov nqi khiav lag luam. Muaj tseeb, hauv Irkut cov lus tshaj tawm, cov nqi khiav lag luam yog 12-15% qis dua, vim tias cov roj yog ob zaug kim dua li tam sim no, uas ua rau qee qhov tsis ntseeg. Nrog rau cov nqi roj qis tam sim no, qhov sib txawv ntawm cov nqi khiav lag luam ntawm cov dav hlau tam sim no thiab cov tiam tom ntej yuav tsum nqaim.
Thaum lub sij hawm nthuav tawm ntawm MS-21, Thawj Tswj Hwm ntawm United Aviation Corporation (UAC), Yuri Slyusar, tau hais hauv lub rooj sib tham xov xwm tias kev sib tw nrog Airbus thiab Boeing yuav tsis yooj yim, tab sis peb ntseeg tias peb lub dav hlau yog technically tshaj. kev sib tw hauv nws chav kawm. chav kawm. Tam sim ntawd tom qab ua koob tsheej, Azerbaijani lub dav hlau AZAL tau kos npe rau daim ntawv cog lus nrog IFC leasing tuam txhab ntawm kev xauj tsev ntawm 10 MS-21 dav hlau tawm ntawm 50 yav dhau los xaj los ntawm IFC los ntawm Irkut.
Ntev sib xyaw tis
Txoj kev daws teeb meem tseem ceeb tshaj plaws rau kev txo cov roj noj yog qhov nyuaj aerodynamics ntawm qhov tshiab 11,5 siab nam piv tis thiab yog li kev ua haujlwm siab aerodynamic. Ntawm qhov ceev ntawm Ma = 0,78, nws cov kev ua haujlwm aerodynamic yog 5,1% zoo dua li ntawm A320, thiab 6,0% zoo dua li ntawm 737NG; ntawm ceev Ma = 0,8, qhov sib txawv yog ntau dua, 6% thiab 7%, feem. Nws yog tsis yooj yim sua kom ua xws li ib tug tis siv classical metallurgical technology (ntau dua precisely, nws yuav hnyav heev), yog li nws yuav tsum tau composite. Cov ntaub ntawv sib xyaw, uas ua rau 35-37% ntawm qhov loj ntawm MS-21 airframe, sib dua, thiab Irkut hais tias ua tsaug rau lawv, qhov hnyav ntawm lub dav hlau ib tus neeg caij tsheb yog li 5% qis dua li ntawm A320, thiab ntau dua 8% qis dua. dua li A320neo (tab sis kuj yog 2% ntau dua li 737).
Ob peb xyoos dhau los, thaum MS-21 qhov kev pab cuam nyuam qhuav pib, Oleg Demchenko, tus thawj tswj hwm ntawm Irkut corporation, tau hais tias MS-21 tau ntsib ob qhov kev sib tw tseem ceeb: cov khoom siv sib xyaw thiab lub cav. Peb yuav rov qab mus rau lub cav tom qab; thiab tam sim no hais txog composites. Cov ntaub ntawv sib xyaw hauv cov khoom me me ntawm cov dav hlau - fairings, npog, rudders - tsis muaj dab tsi tshiab rau ntau xyoo lawm. Txawm li cas los xij, cov khoom sib xyaw load-bearing yog ib qho tshiab ntawm xyoo tas los no. Qhov kev tawg tuaj nrog Boeing 787 Dreamliner, uas yuav luag tag nrho ua los ntawm cov ntaub ntawv sib xyaw, ua raws li Airbus 350. Bombardier CSeries me me tsuas yog muaj cov tis sib xyaw, zoo li MC-21.
