Kūʻē ʻo Irkut i nā pilikua. Hōʻike ʻia ʻo MS-21 ma Irkutsk

Ua wehe ke Kuhina Nui o Rūsia ʻo Dmitry Medvedev i ka MC-21-300, ka mokulele mokulele nui mua o Rūsia i ka hapahā o ke kenekulia, me ka makemake o nā Lūkini e hoʻokūkū me ka Airbus A320 kaulana loa a me Boeing 737. Pyotr Butovsky

Ma Iune 8, 2016, ma Irkutsk mamao ma Lake Baikal, ma ka hangar o ka mea kanu IAZ (Irkutsk Aviation Plant), ua hōʻike mua ʻia kahi mokulele kamaʻilio hou MS-21-300, kahi i kūʻē ai ka Irkut Corporation i ka Airbus A320 a me Boeing 737. MS-21-300 - kumu, 163-noho mana o ka mokulele e hiki mai ana o ka ohana MS-21. Hoʻomaka ka mokulele e lele i kāna lele mua i ka hoʻomaka o ka makahiki aʻe.

Ua hele ke Kuhina Nui o ke Aupuni Lūkia ʻo Dmitry Medvedev, me ka hoʻoikaika ʻana i nā manaʻolana e kau ai ke aupuni Lūkini ma kēia mokulele. ʻO MS-21 kekahi o nā mokulele hou loa o ka honua, he mokulele mokulele o ke kenekulia 21. Haʻaheo loa mākou ua hana ʻia ia ma ko mākou ʻāina. Ua kamaʻilio kaʻawale ʻo Medvedev i nā mea hoʻolako haole i komo i ka papahana MS-XNUMX. He mea koʻikoʻi loa ia iā mākou, ma waho aʻe o kā mākou mea hana mokulele maikaʻi loa, ua komo nā hui haole he nui i ka papahana. Aloha mākou i kēlā poʻe ʻoihana e hana nei ma Rusia, aia nō hoʻi i loko o kēia keʻena i kēia lā a ke holomua nei me ko mākou ʻāina.

Pono ʻo MS-21 i huahana holomua. Hoʻomaopopo ka poʻe Lūkini ʻo ka hoʻohui ʻana i kahi papahana like ʻē aʻe ma hope o ka Airbus 320 a me Boeing 737 (a me ka Chinese C919 hou) ʻaʻole e kū i kahi manawa kūpono. No ka holomua o ka MC-21, pono e ʻoi aku ka maikaʻi ma mua o ka hoʻokūkū. ʻIke ʻia nā manaʻo nui ma ka inoa o ka mokulele: ʻo MS-21 ka mokulele nui o Rūsia o ke kenekulia 21. ʻOiaʻiʻo, pono e unuhi ʻia ka huaʻōlelo Cyrillic MS ma ke ʻano he MS, a ʻo ia ke ʻano i kapa ʻia ai ma nā puke haole mua, akā ua hoʻonohonoho koke ʻo Irkut i nā mea a hoʻoholo i ka inoa honua o kā lākou papahana ʻo MS-21.

Ua hoʻonohonoho pono ʻia ka pahuhopu: ʻo nā kumukūʻai hana pololei o ka mokulele MC-21 he 12-15% haʻahaʻa ma mua o nā mokulele maikaʻi loa o kēia papa (ua lawe ʻia ʻo Airbus A320 ma ke ʻano he laʻana), ʻoiai ʻo 24%. malalo. Ke hoʻohālikelike ʻia me ka A320neo i hoʻonui ʻia, manaʻo ʻia ka MC-1000 e hoʻopau i ka 1852% emi iho ka wahie ma kahi ala maʻamau 21 nautical mile (8 km), me 5% haʻahaʻa haʻahaʻa o nā koina hana. ʻOiaʻiʻo, ma nā ʻōlelo a Irkut, ʻoi aku ka haʻahaʻa o nā kumukūʻai hana he 12-15% haʻahaʻa, ʻoiai ʻelua ʻoi aku ka nui o ka aila e like me kēia manawa, e hoʻāla ana i kekahi mau kānalua. Me ke kumukūʻai haʻahaʻa haʻahaʻa o kēia manawa, pono ka ʻokoʻa o nā kumukūʻai hana ma waena o nā mokulele o kēia manawa a me ka hanauna e hiki mai ana.

I ka wā o ka hōʻike ʻana o ka MS-21, ʻo ka Pelekikena o ka United Aviation Corporation (UAC), ʻo Yuri Slyusar, i ʻōlelo ʻia ma kahi kūkā nūhou ʻaʻole e maʻalahi ka hoʻokūkū me Airbus a me Boeing, akā manaʻo mākou ʻo kā mākou mokulele ka mea ʻoi loa. hoʻokūkū ma kona papa. papa. Ma hope koke iho o ka hana, ua hoʻopaʻa inoa ka mokulele Azerbaijani AZAL i kahi memo me ka hui hoʻolimalima IFC ma ka hiki ke hoʻolimalima o 10 MS-21 mokulele mai 50 i kauoha mua ʻia e IFC mai Irkut.

ʻEheu hui lōʻihi

ʻO ka hopena koʻikoʻi no ka hōʻemi ʻana i ka hoʻohana ʻana i ka wahie, ʻo ia ka aerodynamics paʻakikī o kahi ʻēheu hiʻohiʻona kiʻekiʻe 11,5 hou loa a no laila kiʻekiʻe aerodynamic pono. Ma ka wikiwiki o Ma = 0,78, ʻoi aku ka maikaʻi o kāna aerodynamic 5,1% ma mua o ka A320, a ʻoi aku ka maikaʻi o 6,0% ma mua o ka 737NG; ma ka mama o Ma = 0,8, ua oi aku ka okoa, 6% a me 7%, pakahi. ʻAʻole hiki ke hana i kēlā ʻēheu me ka hoʻohana ʻana i ka ʻenehana metallurgical maʻamau (ʻoi aku ka pololei, he kaumaha loa ia), no laila pono e hoʻohui ʻia. ʻOi aku ka maʻalahi o nā mea hoʻohui, ka mea i 35-37% o ka nui o ka airframe MS-21, a ʻōlelo ʻo Irkut e mahalo iā lākou, ʻo ke kaumaha o ka mokulele i kēlā me kēia mokulele ma kahi o 5% haʻahaʻa ma mua o ka A320. a ʻoi aku ma mua o 8% haʻahaʻa. ma mua o ka A320neo (akā ma kahi o 2% ʻoi aku ma mua o ka 737).

I kekahi mau makahiki i hala aku nei, i ka wā i hoʻomaka ai ka papahana MS-21, ua ʻōlelo ka pelekikena o ka Irkut Corporation, ʻo Oleg Demchenko, ua kū ka MS-21 i ʻelua mau hana ʻenehana nui: nā mea hana a me kahi mīkini. E hoʻi mākou i ka ʻenekini ma hope; a i kēia manawa e pili ana i nā composites. ʻO nā mea hana i loko o nā ʻāpana liʻiliʻi o nā mokulele - nā fairings, nā uhi, nā hoe - ʻaʻohe mea hou no kekahi mau makahiki. Eia nō naʻe, he mea hou nā hale mana composite o nā makahiki i hala iho nei. ʻO ka holomua i hele mai me ka Boeing 787 Dreamliner, kahi i hana ʻia me nā mea i hoʻohui ʻia, a ukali ʻia e ka Airbus 350. ʻO ka Bombardier CSeries liʻiliʻi he ʻēheu composite wale nō, e like me ka MC-21.
