Airbus A350 le Boeing 787 ke mehlala ea mantlha ea lifofane tse ngata tse kholo lefatšeng ka bophara.Ho latela pono ea lifofane, lifofane tsena tse peli tse pharalletseng li ka tlisa tekano e kholo lipakeng tsa melemo ea moruo le boiphihlelo ba bareki nakong ea maeto a malelele.'Me molemo ona o tsoa ho tšebeliso ea bona ea lisebelisoa tse kopantsoeng bakeng sa tlhahiso.
Boleng ba tšebeliso ea thepa e kopantsoeng
Tšebeliso ea lisebelisoa tse kopantsoeng khoebong ea lifofane e na le histori e telele.Lifofane tse nang le 'mele o moqotetsane joalo ka Airbus A320 li se li sebelisitse likarolo tse kopaneng, joalo ka mapheo le mehatla.Lifofane tse pharalletseng, joalo ka Airbus A380, le tsona li sebelisa lisebelisoa tse kopaneng, tse fetang 20% ea fuselage e entsoeng ka thepa e kopaneng.Lilemong tsa morao tjena, tšebeliso ea lisebelisoa tse kopanetsoeng lifofaneng tsa lifofane tsa khoebo e eketsehile haholo 'me e fetohile lisebelisoa tsa tšiea lebaleng la lifofane.Ketsahalo ena ha e makatse, hobane lisebelisoa tse kopantsoeng li na le lintho tse ngata tse molemo.
Ha ho bapisoa le lisebelisoa tse tloaelehileng tse kang aluminium, lisebelisoa tse kopantsoeng li na le molemo oa ho ba bobebe.Ho phaella moo, mabaka a ka ntle a tikoloho a ke ke a etsa hore ho be le lisebelisoa tse entsoeng ka motsoako.Lena ke lona lebaka le ka sehloohong le etsang hore lifofane tse fetang halofo tsa Airbus A350 le Boeing 787 li entsoe ka thepa e kopaneng.
Tšebeliso ea lisebelisoa tse kopaneng ho 787
Ka sebopeho sa Boeing 787, thepa e kopantsoeng e etsa 50%, aluminium 20%, titanium 15%, tšepe 10%, le 5% lisebelisoa tse ling.Boeing e ka rua molemo mohahong ona mme ea fokotsa boima bo bongata.Kaha lisebelisoa tse kopantsoeng li etsa boholo ba mohaho, boima bohle ba sefofane sa baeti bo fokotsehile ka karolelano ea 20%.Ho phaella moo, sebopeho sa motsoako se ka fetoloa ho etsa sebopeho leha e le sefe.Ka hona, Boeing e sebelisitse likarolo tse ngata tsa cylindrical ho theha 787′s fuselage.
Boeing 787 e sebelisa thepa e kopantsoeng ho feta sefofane leha e le sefe sa pele sa Boeing sa khoebo.Ka lehlakoreng le leng, thepa e entsoeng ka Boeing 777 e ne e le 10% feela.Boeing o re keketseho ea ts'ebeliso ea lisebelisoa tse kopaneng e bile le tšusumetso e pharalletseng ho potoloha ha lifofane tsa baeti.Ka kakaretso, ho na le lisebelisoa tse 'maloa tse fapaneng potolohong ea tlhahiso ea lifofane.Ka bobeli Airbus le Boeing ba utloisisa hore bakeng sa polokeho ea nako e telele le melemo ea litšenyehelo, ts'ebetso ea tlhahiso e hloka ho leka-lekana ka hloko.
Airbus e na le ts'epo e kholo ea lisebelisoa tse kopaneng, 'me e chesehela haholo lipolasetiki tse matlafalitsoeng tsa carbon fiber (CFRP).Airbus e boletse hore fuselage ea sefofane e kopaneng e matla ebile e bobebe.Ka lebaka la ho senyeha ho fokotsehileng, sebopeho sa fuselage se ka fokotsoa ka tlhokomelo nakong ea tšebeletso.Ka mohlala, mosebetsi oa tlhokomelo ea mohaho oa fuselage oa Airbus A350 o fokotsehile ka 50%.Ntle le moo, fuselage ea Airbus A350 e hloka feela ho hlahlojoa hang ka mor'a lilemo tse ling le tse ling tse 12, ha nako ea tlhahlobo ea Airbus A380 e le hang ka mor'a lilemo tse ling le tse ling tse 8.
