Airbus A350 thiab Boeing 787 yog cov qauv tseem ceeb ntawm ntau cov huab cua loj thoob ntiaj teb. Los ntawm qhov kev pom ntawm Airlines, ob lub dav hlau dav-lub cev tuaj yeem nqa cov nyiaj tshuav ntawm kev khwv nyiaj txiag thiab cov neeg siv khoom thaum lub sijhawm sib tw ntev. Thiab qhov txiaj ntsig no yog los ntawm lawv siv cov khoom siv sib xyaw rau kev tsim khoom.
Puas Siv Khoom Siv Khoom Siv Khoom Siv
Daim ntawv thov ntawm cov khoom siv sib xyaw ua lag luam hauv kev ua lag luam Aviation muaj keeb kwm ntev. Nqaim-lub cev ua lub cev xws li Airbus A320 twb tau siv cov tshuaj sib xyaw, xws li tis thiab tails. Dav-lub cev airliners, xws li Airbus A380, tseem siv cov khoom siv A380, kuj muaj ntau cov ntaub ntawv, nrog ntau dua 20% ntawm cov fuselage ua los ntawm cov khoom siv sib xyaw. Nyob rau hauv xyoo tsis ntev los no, kev siv cov khoom siv sib xyaw ua lag luam Av lag luam Aircraft tau nce ntau thiab tau dhau los ua cov khoom siv ncej av. Qhov tshwm sim no tsis yog qhov xav tsis thoob, vim tias cov khoom siv sib xyaw muaj ntau yam txiaj ntsig zoo.
Piv nrog cov qauv cov khoom xws li txhuas, cov khoom siv puas muaj qhov zoo ntawm lub teeb yuag. Tsis tas li ntawd, sab nraud ib puag ncig ib puag ncig yuav tsis ua rau hnav rau cov khoom siv sib xyaw. Qhov no yog qhov tseem ceeb vim li cas ntau dua li ib nrab ntawm Airbus A350 thiab Boeing 787 airleirers yog ua los ntawm cov khoom siv sib xyaw.
Daim ntawv thov ntawm cov khoom siv sib xyaw hauv 787
Hauv cov qauv ntawm Boeing 787, Composite Cov Ntaub Ntawv Account rau 50%, Txhuas 20%, titanium 15%, thiab 5% lwm cov ntaub ntawv. Boeing tuaj yeem tau txais txiaj ntsig los ntawm cov qauv no thiab txo cov nqi ntau ntawm qhov hnyav. Txij li cov ntaub ntawv sib xyaw ua feem ntau ntawm cov qauv, tag nrho qhov hnyav ntawm cov neeg caij tsheb nrog cov neeg caij tsheb tau raug txo los ntawm 20%. Tsis tas li ntawd, tus qauv sib xyaw ua ke tuaj yeem hloov kho rau cov duab. Yog li ntawd, boeing siv ntau qhov cylindrical seem los ua lub 787 tus fuselage.
Lub Boeing 787 siv cov khoom siv sib xyaw ntau dua li yav dhau los boeing cov dav hlau ua lag luam. Hauv kev sib piv, Boeing 777 cov khoom siv sib xyaw ua ke rau tsuas yog 10%. Boeing tau hais tias qhov nce hauv kev siv cov khoom siv sib xyaw tau muaj qhov cuam tshuam dav dav ntawm cov neeg caij tsheb txua dav hlau tsim. Nyob rau hauv dav dav, muaj ntau cov ntaub ntawv sib txawv nyob rau hauv lub dav hlau tsim khoom. Ob lub airbus thiab boeing nkag siab tias kom muaj kev nyab xeeb ntev thiab tus nqi tsim nyog, cov txheej txheem kev lag luam yuav tsum ua tib zoo sib npaug.
Airbus tau txiav txim siab kev ntseeg siab nyob rau hauv cov khoom siv sib xyaw, thiab yog tshwj xeeb tshaj yog kees ntawm carbon fiber proferced plastics (CFRP). Airbus hais tias cov tshuab hluav taws xob fuselage muaj zog thiab sib dua. Vim tias cov hnav txo thiab kua muag, cov qauv fuselage tuaj yeem txo nyob rau hauv kev saib xyuas lub sijhawm ua haujlwm. Piv txwv li, txoj haujlwm saib xyuas ntawm Fuselage qauv ntawm lub Airbus A350 tau raug txo los ntawm 50%. Ib qho ntxiv, cov Airbus A350 tsuas yog yuav tsum tau tshuaj xyuas ib zaug txhua 12 xyoos, thaum lub sijhawm kho Airbus A380 soj ntsuam ib zaug yog txhua txhua 8 xyoo.
