I-Airbus A350 kunye ne-Boeing 787 ziimodeli eziphambili zeenqwelo-moya ezininzi ezinkulu kwihlabathi liphela. Ngokwembono yeenqwelo-moya, ezi nqwelo-moya zimbini zibanzi zinokuzisa ulungelelwaniso olukhulu phakathi kweenzuzo zoqoqosho kunye namava abathengi ngexesha lokuhamba ngenqwelo-moya umgama omde. Kwaye le nzuzo ivela ekusebenziseni kwazo izinto ezidityanisiweyo kwimveliso.
Ixabiso lesicelo sezinto ezidityanisiweyo
Ukusetyenziswa kwezinto ezidityanisiweyo kwiinqwelomoya zorhwebo kunembali ende. Iinqwelomoya ezinomzimba omxinwa ezifana ne-Airbus A320 sele zisebenzisa iindawo ezidityanisiweyo, ezifana namaphiko nemisila. Iinqwelomoya ezinomzimba obanzi, ezifana ne-Airbus A380, nazo zisebenzisa izinto ezidityanisiweyo, kunye ne-fuselage engaphezulu kwama-20% eyenziwe ngezinto ezidityanisiweyo. Kwiminyaka yakutshanje, ukusetyenziswa kwezinto ezidityanisiweyo kwiinqwelomoya zorhwebo kuye kwanda kakhulu kwaye kuye kwaba yintsika yezixhobo kwiinqwelomoya. Le nto ayimangalisi, kuba izinto ezidityanisiweyo zineempawu ezininzi eziluncedo.
Xa kuthelekiswa nezinto ezisemgangathweni ezifana ne-aluminium, izinto ezidityanisiweyo zinenzuzo yokuba zikhaphukhaphu. Ukongeza, izinto zangaphandle ezingqongileyo aziyi kubangela ukuguguleka kwezinto ezidityanisiweyo. Esi sesona sizathu siphambili sokuba ngaphezulu kwesiqingatha seenqwelo-moya ze-Airbus A350 kunye ne-Boeing 787 zenziwe ngezinto ezidityanisiweyo.
Ukusetyenziswa kwezinto ezidityanisiweyo kwi-787
Kwisakhiwo seBoeing 787, izinto ezidityanisiweyo zithatha i-50%, i-aluminium 20%, i-titanium 15%, intsimbi 10%, kunye ne-5% yezinye izinto. IBoeing inokuxhamla kwesi sakhiwo kwaye inciphise ubunzima obukhulu. Ekubeni izinto ezidityanisiweyo zenza uninzi lwesakhiwo, ubunzima beenqwelo-moya zabakhweli buncitshiswe ngomyinge we-20%. Ukongeza, isakhiwo esidityanisiweyo sinokulungiswa ukwenza nayiphi na imilo. Ke ngoko, iBoeing isebenzise iindawo ezininzi zesilinda ukwenza i-fuselage ye-787.
I-Boeing 787 isebenzisa izinto ezidityanisiweyo ngaphezu kwayo nayiphi na inqwelo moya yezorhwebo ye-Boeing yangaphambili. Ngokwahlukileyo koko, izinto ezidityanisiweyo ze-Boeing 777 zibize i-10% kuphela. I-Boeing ithe ukwanda kokusetyenziswa kwezinto ezidityanisiweyo kube nefuthe elibanzi kumjikelo wokwenziwa kweenqwelo moya zabakhweli. Ngokubanzi, kukho izinto ezahlukeneyo kumjikelo wokuveliswa kweenqwelo moya. Zombini i-Airbus kunye ne-Boeing ziyaqonda ukuba ukuze kubekho ukhuseleko lwexesha elide kunye neenzuzo zeendleko, inkqubo yokwenziwa kufuneka ilinganiswe ngononophelo.
I-Airbus inentembelo enkulu kwizinto ezidityanisiweyo, kwaye inomdla kakhulu kwiiplastiki eziqinisiweyo ze-carbon fiber (CFRP). I-Airbus ithe i-fuselage yenqwelo-moya edityanisiweyo inamandla kwaye ilula. Ngenxa yokuguguleka okunciphileyo, isakhiwo se-fuselage sinokuncitshiswa xa silungiswa ngexesha lenkonzo. Umzekelo, umsebenzi wokulungisa isakhiwo se-fuselage se-Airbus A350 uncitshiswe ngama-50%. Ukongeza, i-fuselage ye-Airbus A350 kufuneka ihlolwe kube kanye emva kweminyaka eli-12, ngelixa ixesha lokuhlola i-Airbus A380 liba kanye emva kweminyaka esi-8.
