Airbus A350 thiab Boeing 787 yog cov qauv tseem ceeb ntawm ntau lub dav hlau loj thoob ntiaj teb.Los ntawm kev xav ntawm cov dav hlau, ob lub dav hlau dav hlau no tuaj yeem nqa qhov sib npaug loj ntawm cov txiaj ntsig kev lag luam thiab cov neeg siv khoom tau txais kev paub dhau los thaum caij dav hlau ntev.Thiab qhov zoo dua no yog los ntawm lawv cov khoom siv sib xyaw rau kev tsim khoom.
Composite khoom siv tus nqi
Kev siv cov ntaub ntawv sib xyaw hauv kev lag luam aviation muaj keeb kwm ntev.Cov dav hlau nqaim lub cev xws li Airbus A320 twb tau siv cov khoom sib xyaw, xws li tis thiab tails.Lub dav hlau 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 ntaub ntawv sib xyaw hauv kev lag luam aviation aircraft tau nce ntxiv thiab tau dhau los ua cov khoom tseem ceeb hauv kev lag luam aviation.Qhov tshwm sim no tsis yog qhov xav tsis thoob, vim tias cov ntaub ntawv 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, lwm yam ib puag ncig ib puag ncig yuav tsis ua rau hnav rau cov khoom sib xyaw.Qhov no yog qhov laj thawj tseem ceeb vim li cas ntau tshaj li ib nrab ntawm Airbus A350 thiab Boeing 787 airliners yog ua los ntawm cov ntaub ntawv sib xyaw.
Kev siv cov khoom sib xyaw hauv 787
Hauv cov qauv ntawm Boeing 787, cov ntaub ntawv sib xyaw suav nrog 50%, aluminium 20%, titanium 15%, steel 10%, thiab 5% lwm cov ntaub ntawv.Boeing tuaj yeem tau txais txiaj ntsig los ntawm cov qauv no thiab txo qhov hnyav hnyav.Txij li cov ntaub ntawv sib xyaw ua rau feem ntau ntawm cov qauv, tag nrho qhov hnyav ntawm cov neeg caij dav hlau tau raug txo los ntawm qhov nruab nrab ntawm 20%.Tsis tas li ntawd, cov qauv sib xyaw tuaj yeem hloov kho los tsim txhua yam duab.Yog li ntawd, Boeing siv ntau qhov chaw cylindrical los tsim lub 787's fuselage.
Lub Boeing 787 siv cov ntaub ntawv sib xyaw ntau dua li yav dhau los Boeing kev lag luam dav hlau.Hauv qhov sib piv, Boeing 777's cov ntaub ntawv sib xyaw suav tsuas yog 10%.Boeing tau hais tias qhov nce ntawm kev siv cov khoom sib xyaw ua ke tau muaj kev cuam tshuam ntau dua rau cov neeg caij dav hlau tsim lub voj voog.Feem ntau, muaj ntau yam khoom sib txawv hauv lub voj voog tsim dav hlau.Ob Airbus thiab Boeing nkag siab tias kom muaj kev nyab xeeb mus sij hawm ntev thiab cov txiaj ntsig zoo, cov txheej txheem tsim khoom yuav tsum ua tib zoo sib npaug.
Airbus muaj kev ntseeg siab ntau hauv cov ntaub ntawv sib xyaw, thiab tshwj xeeb tshaj yog rau cov pa roj carbon fiber reinforced plastics (CFRP).Airbus tau hais tias lub dav hlau sib xyaw ua ke muaj zog dua thiab sib dua.Vim qhov txo qis hnav thiab tsim kua muag, lub fuselage qauv tuaj yeem txo qis hauv kev saib xyuas thaum ua haujlwm.Piv txwv li, kev saib xyuas ntawm lub fuselage qauv ntawm Airbus A350 tau raug txo los ntawm 50%.Tsis tas li ntawd, lub fuselage Airbus A350 tsuas yog yuav tsum tau tshuaj xyuas ib zaug txhua 12 xyoo, thaum lub sijhawm tshuaj xyuas Airbus A380 yog ib zaug txhua 8 xyoo.
