U-Irkut uphonsela inselelo imidondoshiya. I-MS-21 ikhonjiswe e-Irkutsk
UNdunankulu waseRussia uDmitry Medvedev wembula i-MC-21-300, indiza yokuqala enkulu yabagibeli yaseRussia esikhathini esingangekota yekhulu, abantu baseRussia abafuna ukuncintisana nayo ne-Airbus A320 edume kakhulu emhlabeni kanye ne-Boeing 737. UPyotr Butovsky
NgoJuni 8, 2016, e-Irkutsk ekude eLake Baikal, endaweni yokuphakelwa kwesitshalo se-IAZ (Irkutsk Aviation Plant), kwethulwa okokuqala indiza entsha yezokuxhumana i-MS-21-300, lapho i-Irkut Corporation inselele i-Airbus A320 ne-Boeing 737. I-MS-21-300 - inguqulo eyisisekelo, enezihlalo ezingu-163 yendiza yesikhathi esizayo yomndeni we-MS-21. Indiza kulindeleke ukuthi isuke endizeni yayo yokuqala ngasekuqaleni konyaka ozayo.
Lo mcimbi ubuhanjelwe uNdunankulu kaHulumeni waseRussia uDmitry Medvedev, egcizelela amathemba uhulumeni waseRussia uwabeke kule ndiza. I-MS-21 ingenye yezindiza zesimanje kakhulu emhlabeni, indiza yabagibeli yekhulu lama-21. Siyaziqhenya kakhulu ngokuthi yadalwa ezweni lethu. UMedvedev ukhulume ngokuhlukene nabahlinzeki bangaphandle ababambe iqhaza kuphrojekthi ye-MS-XNUMX. Kubaluleke kakhulu kithi ukuthi, ngaphezu kwabakhiqizi bethu bezindiza abahamba phambili, izinkampani eziningi zakwamanye amazwe zibambe iqhaza kulo msebenzi. Sithulela isigqoko labo somabhizinisi abasebenza eRussia, nabo abakuleli hholo namuhla futhi abenza intuthuko enkulu ngokubambisana nezwe lethu.
I-MS-21 kufanele ibe umkhiqizo ophumelelayo. Abantu baseRussia bayaqonda ukuthi ukwengeza enye iphrojekthi efanayo eduze kwe-Airbus 320 ne-Boeing 737 (kanye ne-C919 entsha yaseChina) ngeke kube sethubeni lokuphumelela. Ukuze i-MC-21 iphumelele, kufanele ibe ngcono ngokuphawulekayo kunomncintiswano. Izifiso ezinkulu sezivele zibonakala egameni lendiza: i-MS-21 iyindiza yaseRussia ehamba phambili yekhulu lama-21. Empeleni, igama lesiCyrillic elithi MS kufanele lihunyushwe ngokuthi MS, futhi yindlela elalibizwa ngayo kanjalo ezincwadini zokuqala zakwamanye amazwe, kodwa u-Irkut washeshe wabeka izinto ngohlelo futhi wanquma ukuqokwa kwamazwe ngamazwe kwephrojekthi yabo njenge-MS-21.
Umgomo wawubekwe ngokucacile: izindleko eziqondile zokusebenza zendiza ye-MC-21 kufanele zibe ngaphansi kuka-12-15% kunalezo zezindiza zesimanje ezingcono kakhulu zalesi sigaba (i-Airbus A320 ithathwa njengesibonelo), kanti ukusetshenziswa kukaphethiloli kungu-24%. ngezansi. Uma kuqhathaniswa ne-A320neo ethuthukisiwe, i-MC-1000 kulindeleke ukuthi isebenzise uphethiloli ongaphansi ngo-1852% emzileni ojwayelekile wamamayela angu-21 we-nautical (8 km), nezindleko zokusebenza eziqondile eziphansi ngo-5%. Yiqiniso, ezimemezelweni zika-Irkut, izindleko zokusebenza ziphansi ngo-12-15%, njengoba uwoyela wawubiza kabili njengoba unjalo manje, okuphakamisa ukungabaza okuthile. Ngenani eliphansi lamanje likaphethiloli, umehluko ezindlekweni zokusebenza phakathi kwendiza yamanje nesizukulwane esilandelayo kufanele ube mncane.
Ngesikhathi kwethulwa i-MS-21, uMongameli we-United Aviation Corporation (UAC), u-Yuri Slyusar, uthe esithangamini nabezindaba ukuthi ukuncintisana ne-Airbus ne-Boeing ngeke kube lula, kodwa sikholelwa ukuthi indiza yethu iyona ehamba phambili kakhulu. ukuncintisana ekilasini layo. ikilasi. Ngokushesha ngemva komkhosi, inkampani yezindiza yase-Azerbaijan i-AZAL isayine imemorandamu nenkampani eqashisayo ye-IFC mayelana nokuqashiswa okungenzeka kwezindiza eziyi-10 MS-21 kwezingu-50 ezazi-odwe ngaphambilini yi-IFC yase-Irkut.
Uphiko olude oluyinhlanganisela
Isixazululo esibaluleke kakhulu sokunciphisa ukusetshenziswa kukaphethiloli i-aerodynamics eyinkimbinkimbi yophiko olusha ngokuphelele lwe-11,5 high aspect ratio futhi ngenxa yalokho ukusebenza kahle kwe-aerodynamic. Ngesivinini se-Ma = 0,78, ukusebenza kahle kwayo kwe-aerodynamic kungcono ngo-5,1% kune-A320, futhi i-6,0% engcono kunaleyo ye-737NG; ngesivinini Ma = 0,8, umehluko mkhulu nakakhulu, 6% no-7%, ngokulandelana. Akunakwenzeka ukwenza iphiko elinjalo usebenzisa ubuchwepheshe be-classical metallurgical (ngokuqondile, kungaba nzima kakhulu), ngakho-ke kufanele kube yinhlanganisela. Izinto ezihlanganisiwe, ezakha u-35-37% wesisindo se-MS-21 airframe, zilula, futhi u-Irkut uthi ngenxa yabo, isisindo esingenalutho sendiza ngomgibeli ngamunye singaphansi ngo-5% kune-A320, futhi ngaphansi kuka-8%. kune-A320neo (kodwa futhi cishe ngo-2% ngaphezu kwe-737).
Eminyakeni embalwa edlule, lapho uhlelo lwe-MS-21 lusanda kuqala, u-Oleg Demchenko, umongameli we-Irkut corporation, wathi i-MS-21 ibhekene nezinselele ezimbili eziyinhloko zobuchwepheshe: izinto eziyinhlanganisela kanye nenjini. Sizobuyela enjinini kamuva; futhi manje mayelana nezinhlanganisela. Izinto ezihlanganisiwe ezingxenyeni ezincane zezindiza - ama-fairing, amakhava, ama-rudders - bekuyinto entsha emashumini ambalwa eminyaka. Kodwa-ke, izakhiwo zamandla eziyinhlanganisela ziyinto entsha yeminyaka yamuva. Ukuphumelela kuqhamuke ne-Boeing 787 Dreamliner, cishe eyenziwe ngezinto eziyinhlanganisela, ilandelwa yi-Airbus 350. I-Bombardier CSeries encane inophiko oluyinhlanganisela kuphela, njenge-MC-21.
