Airbus A350 le Boeing 787 ke mehlala e meholo ea lifofane tse ngata tse kholo lefatšeng ka bophara. Ho ea ka pono ea lifofane, lifofane tsena tse peli tse sephara li ka tlisa tekano e kholo lipakeng tsa melemo ea moruo le phihlelo ea bareki nakong ea lifofane tse telele. 'Me molemo ona o tsoa tšebelisong ea tsona ea thepa e kopaneng bakeng sa tlhahiso.
Boleng ba kopo ea thepa e kopaneng
Tšebeliso ea thepa e kopaneng lifofaneng tsa khoebo e na le nalane e telele. Lifofane tse nang le 'mele o moqotetsane tse kang Airbus A320 li se li sebelisitse likarolo tse kopaneng, tse kang mapheo le mehatla. Lifofane tse nang le 'mele o moholo, tse kang Airbus A380, le tsona li sebelisa thepa e kopaneng, ka karolo e fetang 20% ea fuselage e entsoeng ka thepa e kopaneng. Lilemong tsa morao tjena, tšebeliso ea thepa e kopaneng lifofaneng tsa lifofane tsa khoebo e eketsehile haholo 'me e fetohile thepa ea tšiea lefapheng la lifofane. Ketsahalo ena ha e makatse, hobane thepa e kopaneng e na le litšobotsi tse ngata tse molemo.
Ha ho bapisoa le thepa e tloaelehileng e kang aluminium, thepa e kopantsoeng e na le monyetla oa ho ba bobebe. Ho feta moo, mabaka a kantle a tikoloho a ke ke a baka ho tsofala ha thepa e kopantsoeng. Lena ke lebaka la bohlokoa leo ka lona lifofane tse fetang halofo tsa Airbus A350 le Boeing 787 li entsoeng ka thepa e kopantsoeng.
Tšebeliso ea thepa e kopaneng ka 787
Sebopehong sa Boeing 787, thepa e kopaneng e etsa 50%, aluminium 20%, titanium 15%, tšepe 10%, le 5% ea thepa e meng. Boeing e ka rua molemo mohahong ona 'me ea fokotsa boima bo bongata. Kaha thepa e kopaneng e etsa boholo ba sebopeho, boima bohle ba sefofane sa bapalami bo fokotsehile ka karolelano ea 20%. Ho phaella moo, sebopeho se kopaneng se ka fetoloa ho etsa sebopeho leha e le sefe. Ka hona, Boeing e sebelisitse likarolo tse ngata tsa cylindrical ho theha fuselage ea 787.
Boeing 787 e sebelisa thepa e kopaneng ho feta sefofane sefe kapa sefe sa khoebo sa Boeing. Ka lehlakoreng le leng, thepa e kopaneng ea Boeing 777 e ne e ikarabella bakeng sa 10% feela. Boeing e itse keketseho ea tšebeliso ea thepa e kopaneng e bile le tšusumetso e pharaletseng potolohong ea tlhahiso ea lifofane tsa bapalami. Ka kakaretso, ho na le thepa e 'maloa e fapaneng potolohong ea tlhahiso ea lifofane. Airbus le Boeing ka bobeli lia 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 tshepo e kgolo disebedisweng tse kopaneng, mme e rata haholo dipolasetiki tse matlafaditsweng ka faeba ya khabone (CFRP). Airbus e itse fuselage ya sefofane se kopaneng e matla ebile e bobebe. Ka lebaka la ho senyeha le ho taboha ho fokotsehileng, sebopeho sa fuselage se ka fokotswa tlhokomelong nakong ya tshebeletso. Mohlala, mosebetsi wa tlhokomelo ya sebopeho sa fuselage sa Airbus A350 o fokotsehile ka 50%. Ho feta moo, fuselage ya Airbus A350 e hloka ho hlahlojwa hang feela dilemong tse ding le tse ding tse 12, ha nako ya tlhahlobo ya Airbus A380 e le hang dilemong tse ding le tse ding tse 8.
