Airbus A380 vs Boeing 787 Dreamliner
Airbus A380 thiab Boeing 787 Dreamliner yog cov dav hlau lag luam tshiab tshaj plaws tsim thiab tsim los ntawm Airbus (EU) thiab Boeing (USA). Airbus A380 tau qhia txog kev lag luam aviation nrog Singapore Airlines thaum Lub Kaum Hli 2007, thiab Boeing 787 tau ua nws thawj zaug kev lag luam nyob rau lub Kaum Hlis 2011 nrog tag nrho Nippon Airlines. Ob lub dav hlau tau cim qhov tseem ceeb hauv keeb kwm aviation; A380 yog lub tuam txhab ua haujlwm loj tshaj plaws thiab Boeing 787 lees tias yog lub dav hlau siv roj ntau tshaj hauv ntiaj teb.
Airbus tsim A380 kom dhau lub lag luam Boeing rau lub dav hlau dav hlau dav hlau dav hlau uas tau tswj hwm los ntawm Boeing 747 series, muab cov roj ntau ntxiv thiab qhov chaw hauv A380. Tab sis Boeing teb nrog lawv cov Boeing -787 Dreamliner, uas yog me dua A380 tab sis muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo rau cov dav hlau. Cov dav hlau no yog sim los ntawm ob lub tuam txhab hauv lawv cov kev sib tw rau kev tswj hwm hauv kev tsim dav hlau.
Ntau txog Airbus A380
Airbus A380 yog tus neeg caij tsheb loj tshaj plaws uas muaj peev xwm zaum ntawm 555 hauv kev teeb tsa tus qauv. Qhov chaw nyob tsis tau muaj dua los ntawm lub dav hlau tso cai rau kev hloov kho sab hauv sab hauv ntxiv rau cov neeg siv khoom xws li tuav, chaw kho kom zoo nkauj, khw tsis muaj lub luag haujlwm, thiab tsev noj mov txhawm rau txhim kho cov neeg caij dav hlau.
Txawm tias lub dav hlau loj dua li feem ntau ntawm cov dav hlau thiab cov suab nrov hauv tsev yog 50% qis dua; Tsis tas li ntawd, nws muaj qis dua emissions dua li cov dav hlau ntawm tib chav kawm (ex. Boeing 747-400). Lub A380 muaj lub xeev ntawm cov kos duab Fly-los-wire ya davhlau tswj system, thiab nws yog thawj coj mus muag dav hlau siv Integrated Modular Avionics (IMA) uas yog ib tug advanced tub rog fighter dav hlau avionics system tsim los ntawm Thales Group siv nyob rau hauv F-22. thiab Dassault Rafale.
Ntau txog Boeing 787 Dreamliner
Nyob rau hauv kev tsim Boeing 787 Dreamliner niaj hnub tshiab engineering tau qhia, pioneering chav kawm tshiab ntawm cov dav hlau thiab ua rau nws yog ib lub dav hlau ua tau zoo tshaj plaws uas tau tsim. Nws lub cev muaj 50% cov ntaub ntawv sib xyaw (txog 32000 kg ntawm CFRP) nyob rau hauv lub fuselage thiab tis. Nws yog 20% roj ntau dua li cov dav hlau ntawm tib chav kawm (ex. Airbus A350) vim yog cov tshuab thev naus laus zis tau tshaj tawm hauv 787, thiab nws tsim tawm 20% tsawg dua.
Ib qho kev nce qib tseem ceeb ntawm kev tsim yog qhov txo qis hauv qhov suav (ex. 1, 500 aluminium ntawv thiab 40, 000 - 50, 000 fasteners muab 80% txo cov fasteners), ua rau 30% txo, hauv cov nqi kho mob. Tsis tas li ntawd, lub tshuab hluav taws xob tshiab tau lees paub 35 feem pua tsawg zog los ntawm cov cav ntau dua li cov tshuab pneumatic ib txwm siv ntawm cov dav hlau niaj hnub thiab siv li 10 km ntawm cov xov tooj liab raug tshem tawm.
