SiC/SiCinokumelana nobushushu okugqwesileyo kwaye iya kuthatha indawo ye-superalloy kwisicelo se-injini yomoya
Umlinganiselo ophakamileyo wokutyhalela kubunzima yinjongo yeenjini zomoya eziphucukileyo. Nangona kunjalo, ngokunyuka komlinganiselo we-thrust-to-weight, iqondo lokushisa lokungena kwi-iturbine lihlala lisanda, kwaye inkqubo ekhoyo ye-superalloy imathiriyeli kunzima ukuhlangabezana neemfuno zee-injini zomoya eziphucukileyo. Umzekelo, ubushushu be-injini ye-injini ye-injini esele ikhona kunye ne-thrust-to-weight ratio yenqanaba le-10 ifikelele kwi-1500 ℃, ngelixa i-avareji yobushushu be-injini ye-injini ene-thrust-to-weight ratio ye-12 ~ 15 iya kudlula i-1800 ℃. kude ngaphaya kobushushu benkonzo yee-superalloys kunye ne-intermetallic compounds.
Okwangoku, i-nickel-based superalloy enokumelana nobushushu kunokufikelela kuphela malunga ne-1100 ℃. Ubushushu benkonzo yeSiC/SiC bunganyuswa ukuya kwi-1650℃, ethathwa njengeyona nto ifanelekileyo ye-aero-injini eshushu yokwakhiwa kwesixhobo.
EYurophu nase-United States nakwamanye amazwe aphuhlileyo ngeenqwelomoya,SiC/SiCibe nokusetyenziswa okusebenzayo kunye nokuveliswa kobuninzi kwiindawo ezimileyo ze-aero-injini, kubandakanywa i-M53-2, i-M88, i-M88-2, i-F100, i-F119, i-EJ200, i-F414, i-F110, i-F136 kunye nezinye iintlobo ze-injini ye-aero-ejenti / yoluntu; Ukusetyenziswa kwamacandelo ajikelezayo kusekho kwinqanaba lophuhliso kunye novavanyo. Uphando olusisiseko e-China luqale kancinci, kwaye kukho umsantsa omkhulu phakathi kwalo kunye nobunjineli basebenzise uphando kumazwe angaphandle, kodwa luphumelele.
NgoJanuwari 2022, uhlobo olutsha lwe-ceramic matrix composite yiyunivesithi yasemntla-ntshona yepolytechnical isebenzisa izixhobo zasekhaya ukwakha idiskhi ye-injini ye-injini yeenqwelo-moya epheleleyo ekugqityweni ngempumelelo kovavanyo lokuqala lokubhabha, ikwalixesha lokuqala i-ceramic matrix composite rotor exhotyiswe ngenqwelomoya. iqonga lovavanyo, kodwa nokukhuthaza amacandelo eekhompositi ze-ceramic matrix kwinqwelo-moya engenabantu (uav)/i-drone yosetyenziso olukhulu.
