Airbus A350 ndi Boeing 787 ndi mitundu yodziwika bwino yamakampani akuluakulu padziko lonse lapansi.Malinga ndi momwe ndege zimayendera, ndege ziwiri zazikuluzikuluzi zimatha kubweretsa mgwirizano waukulu pakati pa phindu lazachuma ndi chidziwitso chamakasitomala pamaulendo apamtunda wautali.Ndipo mwayi uwu umabwera chifukwa chogwiritsa ntchito zinthu zophatikizika popanga.
Mtengo wogwiritsa ntchito kompositi
Kugwiritsiridwa ntchito kwa zinthu zophatikizika pazamalonda zandege kwakhala ndi mbiri yakale.Ndege zopapatiza ngati Airbus A320 zagwiritsapo kale mbali zophatikizika, monga mapiko ndi michira.Ndege zamitundumitundu, monga Airbus A380, zimagwiritsanso ntchito zida zophatikizika, zopitilira 20% za fuselage zopangidwa ndi zinthu zophatikizika.M'zaka zaposachedwa, kugwiritsa ntchito zida zophatikizika mu ndege zamalonda zakwera kwambiri ndipo zakhala mizati m'munda wa ndege.Izi sizosadabwitsa, chifukwa zida zophatikizika zili ndi zinthu zambiri zopindulitsa.
Poyerekeza ndi zida zokhazikika monga aluminiyamu, zida zophatikizika zimakhala ndi mwayi wopepuka.Kuphatikiza apo, zinthu zachilengedwe zakunja sizingapangitse kuvala kwa zinthu zophatikizika.Ichi ndiye chifukwa chachikulu chomwe opitilira theka la ndege za Airbus A350 ndi Boeing 787 amapangidwa ndi zida zophatikizika.
Kugwiritsa ntchito zinthu zophatikizika mu 787
Mu kapangidwe ka Boeing 787, zida zophatikizika zimawerengera 50%, aluminium 20%, titaniyamu 15%, chitsulo 10%, ndi 5% zida zina.Boeing ikhoza kupindula ndi kapangidwe kameneka ndikuchepetsa kulemera kwakukulu.Popeza zida zophatikizika zimapanga zambiri mwamapangidwewo, kulemera konse kwa ndege zonyamula anthu kwachepetsedwa ndi 20%.Kuphatikiza apo, mawonekedwe ophatikizika amatha kusinthidwa kuti apange mawonekedwe aliwonse.Chifukwa chake, Boeing adagwiritsa ntchito ma cylindrical parts angapo kupanga fuselage ya 787′s.
Boeing 787 imagwiritsa ntchito zida zophatikizika kuposa ndege zonse zam'mbuyomu za Boeing.Mosiyana ndi izi, zida za Boeing 777 zidapanga 10% yokha.Boeing adati kuwonjezeka kwa kugwiritsa ntchito zida zophatikizika kwakhudzanso kwambiri kayendedwe ka ndege zonyamula anthu.Mwambiri, pali zinthu zingapo zosiyanasiyana pakupanga ndege.Onse a Airbus ndi Boeing amamvetsetsa kuti chitetezo cha nthawi yayitali komanso phindu lamtengo wapatali, njira yopangira zinthu iyenera kukhala yoyenera.
Airbus imakhulupirira kwambiri zinthu zopangidwa, ndipo imakonda kwambiri mapulasitiki a carbon fiber reinforced (CFRP).Airbus adanena kuti fuselage ya ndegeyi ndi yamphamvu komanso yopepuka.Chifukwa cha kuchepa kwachangu ndi kung'ambika, mawonekedwe a fuselage amatha kuchepetsedwa pakukonza panthawi yautumiki.Mwachitsanzo, ntchito yokonza fuselage ya Airbus A350 yachepetsedwa ndi 50%.Kuphatikiza apo, fuselage ya Airbus A350 imangofunika kuyang'aniridwa kamodzi pazaka 12 zilizonse, pomwe nthawi yoyendera ya Airbus A380 imakhala kamodzi pazaka 8 zilizonse.
