Isantya senqwelo-moya yanamhlanje siye safikelela ngaphezu kwe-2,7 yesantya sesandi.Ukubhabha okukhawulezileyo okunjalo kuya kubangela ukuba inqwelo-moya ihlikihle emoyeni kwaye ikhuphe ubushushu obuninzi.Xa isantya sokubhabha sifikelela kumaxesha angama-2.2 kwisantya sesandi, i-alloy ye-aluminiyam ayikwazi ukumelana nayo.Kufuneka kusetyenziswe ingxubevange yetitanium ekwaziyo ukumelana nobushushu obuphezulu.Okulandelayo, iNgcali evela kwiSebe leTekhnoloji yeRSM iya kubelana ngesizathu sokuba iithagethi ze-titanium alloy zibalulekile kwintsimi ye-aviation!
Xa umlinganiselo wokutyhala kubunzima be-aeroengine yonyuswa ukusuka ku-4 ukuya ku-6 ukuya ku-8 ukuya kwi-10, kwaye iqondo lobushushu le-compressor lendawo yokuphuma liye lenyuka ngokuhambelanayo ukusuka kuma-200 ukuya kuma-300 ℃ ukuya kuma-500 ukuya kuma-600 ℃, idisk ephantsi yoxinzelelo lwecompressor kunye neblade eyenziwe ekuqaleni. i-aluminiyam kufuneka itshintshwe nge-titanium alloy.
Kwiminyaka yakutshanje, izazinzulu zenze inkqubela entsha kuphando lweepropathi ze-titanium alloys.I-alloy ye-titanium yokuqala eyenziwe nge-titanium, i-aluminiyam kunye ne-vanadium inobushushu obuphezulu bokusebenza obuyi-550 ℃ ~ 600 ℃, ngelixa i-alloy esanda kuveliswa ye-aluminiyam titanate (TiAl) inobushushu bokusebenza obuninzi obuyi-1040 ℃.
Ukusebenzisa i-titanium alloy endaweni yensimbi engenasici ukwenza i-high-pressure compressor disks kunye ne-blades kunokunciphisa ubunzima besakhiwo.Amafutha anokongiwa nge-4% rhoqo nge-10% yokunciphisa ubunzima benqwelomoya.Kwi-rocket, rhoqo ukucutha kwe-1kg kunokunyusa uluhlu nge-15km.
Kuya kubonakala ukuba izinto zokulungisa i-titanium alloy ziya kusetyenziswa ngakumbi nangakumbi kwi-aviation, kwaye abavelisi abakhulu be-titanium alloy kufuneka bazinikele kuphando kunye nophuhliso kunye nokuveliswa kwee-alloys eziphezulu ze-titanium ukuqinisekisa indawo kwimarike ye-titanium alloy.
