I-SiC/SiCinokumelana nokushisa okuhle kakhulu futhi izothatha indawo ye-superalloy ekusetshenzisweni kwe-aero-injini
I-high thrust-to-weight ratio umgomo wezinjini ezithuthukisiwe ze-aero. Kodwa-ke, ngokwenyuka kwesilinganiso se-thrust-to-weight, izinga lokushisa le-turbine inlet lilokhu likhuphuka, futhi uhlelo olukhona lwe-superalloy material lunzima ukuhlangabezana nezidingo zezinjini ezithuthukisiwe ze-aero. Isibonelo, izinga lokushisa le-turbine inlet yezinjini ezikhona ezine-thrust-to-weight ratio yezinga le-10 selifinyelele ku-1500 ℃, kanti izinga lokushisa eliphakathi kwezinjini ezine-thrust-to-weight ratio engu-12 ~ 15 lizodlula i-1800 ℃, kude kakhulu nezinga lokushisa lesevisi lama-superalloys kanye nezinhlanganisela ze-intermetallic.
Njengamanje, i-superalloy esekwe ku-nickel enokumelana nokushisa okungcono kakhulu ingafinyelela cishe ku-1100 ℃. Izinga lokushisa lesevisi ye-SiC/SiC linganyuswa libe ngu-1650 ℃, elithathwa njengento ekahle kakhulu yesakhiwo se-aero-injini eshisayo yokugcina.
E-Europe nase-United States nakwamanye amazwe athuthukile ezondiza,I-SiC/SiCkube ukusetshenziswa okusebenzayo kanye nokukhiqizwa kwenqwaba ezingxenyeni ezimile ze-aero-injini, okuhlanganisa i-M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 nezinye izinhlobo zezinjini ze-aero-zempi / zomphakathi; Ukusetshenziswa kwezingxenye ezijikelezayo kusesesigabeni sokuthuthuka nokuhlolwa. Ucwaningo oluyisisekelo eShayina luqale kancane, futhi kunegebe elikhulu phakathi kwalo kanye nobunjiniyela basebenzise ucwaningo emazweni angaphandle, kodwa futhi luphumelele.
NgoJanuwari 2022, uhlobo olusha lwe-ceramic matrix composite yinyuvesi esenyakatho-ntshonalanga ye-polytechnical esebenzisa izinto zasekhaya ukwakha idiski ye-turbine yendiza yendiza ephelele ukuphothula ukuhlolwa kokuqala kwendiza, futhi kungokokuqala ngqa ukuthi i-ceramic matrix composite rotor ifakwe indiza yomoya. inkundla yokuhlola, kodwa futhi ukukhuthaza izingxenye zenhlanganisela ye-ceramic matrix ku-aircraft engenamuntu (uav)/drone application enkulu.
