Airbus A350 thiab Boeing 787 yog cov qauv tseem ceeb ntawm ntau lub dav hlau loj thoob plaws ntiaj teb. Los ntawm qhov kev xav ntawm cov dav hlau, ob lub dav hlau dav dav no tuaj yeem coj qhov sib npaug loj ntawm cov txiaj ntsig kev lag luam thiab kev paub ntawm cov neeg siv khoom thaum lub sijhawm ya dav hlau ntev. Thiab qhov zoo no los ntawm lawv siv cov ntaub ntawv sib xyaw rau kev tsim khoom.
Tus nqi ntawm daim ntawv thov khoom sib xyaw
Kev siv cov khoom sib xyaw hauv kev lag luam dav hlau muaj keeb kwm ntev. Cov dav hlau nqaim xws li Airbus A320 twb tau siv cov khoom sib xyaw, xws li tis thiab tus tw. Cov dav hlau dav hlau, xws li Airbus A380, kuj siv cov khoom sib xyaw, nrog ntau dua 20% ntawm lub fuselage ua los ntawm cov khoom sib xyaw. Nyob rau hauv xyoo tas los no, kev siv cov khoom sib xyaw hauv cov dav hlau dav hlau tau nce ntxiv ntau thiab tau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam dav hlau. Qhov xwm txheej no tsis yog qhov xav tsis thoob, vim tias cov khoom sib xyaw muaj ntau yam zoo.
Piv nrog cov ntaub ntawv txheem xws li txhuas, cov ntaub ntawv sib xyaw muaj qhov zoo ntawm lub teeb yuag. Tsis tas li ntawd, cov yam ntxwv sab nraud yuav tsis ua rau cov ntaub ntawv sib xyaw hnav. Qhov no yog qhov laj thawj tseem ceeb vim li cas ntau dua ib nrab ntawm Airbus A350 thiab Boeing 787 airliners yog ua los ntawm cov ntaub ntawv sib xyaw.
Kev siv cov ntaub ntawv sib xyaw hauv 787
Hauv cov qauv ntawm Boeing 787, cov ntaub ntawv sib xyaw ua ke suav txog 50%, txhuas 20%, titanium 15%, hlau 10%, thiab 5% lwm yam khoom siv. Boeing tuaj yeem tau txais txiaj ntsig los ntawm cov qauv no thiab txo qhov hnyav ntau. Txij li thaum cov ntaub ntawv sib xyaw ua rau feem ntau ntawm cov qauv, tag nrho qhov hnyav ntawm lub dav hlau neeg caij tau raug txo los ntawm qhov nruab nrab ntawm 20%. Tsis tas li ntawd, cov qauv sib xyaw tuaj yeem hloov kho kom tsim tau txhua yam duab. Yog li ntawd, Boeing siv ntau qhov cylindrical los tsim lub fuselage 787.
Lub Boeing 787 siv cov khoom sib xyaw ntau dua li lwm lub dav hlau Boeing yav dhau los. Qhov sib txawv, cov khoom sib xyaw ntawm Boeing 777 tsuas yog 10% xwb. Boeing hais tias kev siv cov khoom sib xyaw ntau ntxiv tau muaj kev cuam tshuam dav dua rau lub voj voog tsim khoom dav hlau. Feem ntau, muaj ntau yam khoom sib txawv hauv lub voj voog tsim khoom dav hlau. Airbus thiab Boeing ob leeg nkag siab tias rau kev nyab xeeb mus sij hawm ntev thiab cov nqi zoo dua, cov txheej txheem tsim khoom yuav tsum tau ua tib zoo sib npaug.
Airbus muaj kev ntseeg siab rau cov ntaub ntawv sib xyaw, thiab tshwj xeeb tshaj yog nyiam cov yas carbon fiber reinforced plastics (CFRP). Airbus hais tias lub dav hlau composite fuselage muaj zog dua thiab sib dua. Vim yog qhov hnav thiab tsim kua muag tsawg dua, cov qauv fuselage tuaj yeem txo qis thaum lub sijhawm kho. Piv txwv li, txoj haujlwm kho ntawm cov qauv fuselage ntawm Airbus A350 tau raug txo los ntawm 50%. Tsis tas li ntawd, lub Airbus A350 fuselage tsuas yog yuav tsum tau kuaj xyuas ib zaug txhua 12 xyoos, thaum lub sijhawm kuaj xyuas Airbus A380 yog ib zaug txhua 8 xyoos.
