SiC / SiCifite ubushyuhe bwiza cyane kandi izasimbuza superalloy mugukoresha aero-moteri
Ikigereranyo cyo hejuru-ku buremere ni intego ya moteri yateye imbere. Ariko, hamwe no kwiyongera kwingero-z-uburemere, ubushyuhe bwa turbine bwinjira bukomeza kwiyongera, kandi sisitemu yibikoresho ya superalloy iragoye kuzuza ibisabwa na moteri yateye imbere. Kurugero, ubushyuhe bwa turbine bwinjizwamo moteri zisanzwe zifite igipimo cyo guterera-uburemere kurwego rwa 10 kigeze kuri 1500 ℃, mugihe impuzandengo yubushyuhe bwa moteri ya moteri ifite igipimo cya 12 ~ 15 kizarenga 1800 ℃, aribyo kure cyane yubushyuhe bwa serivisi ya superalloys hamwe na intermetallic compound.
Kugeza ubu, nikel ishingiye kuri superalloy hamwe nubushyuhe bwiza irashobora kugera kuri 1100 gusa. Ubushyuhe bwa serivisi ya SiC / SiC bushobora kwiyongera kugera kuri 1650 ℃, bufatwa nkibikoresho byiza bya aero-moteri nziza cyane.
Mu Burayi no muri Amerika no mu bindi bihugu byateye imbere mu ndege,SiC / SiCyabaye ingirakamaro kandi itanga umusaruro mwinshi mubice bya moteri ya aero-moteri, harimo M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 nubundi bwoko bwa moteri ya gisirikari / sivile; Gukoresha ibice bizunguruka biracyari murwego rwiterambere no kugerageza. Ubushakashatsi bwibanze mu Bushinwa bwatangiye buhoro, kandi hari itandukaniro rinini hagati yacyo n’ubushakashatsi bwakoreshejwe mu buhanga mu bihugu by’amahanga, ariko kandi bumaze kugeraho.
Muri Mutarama 2022, ubwoko bushya bwa ceramic matrix composite ni muri kaminuza yuburengerazuba bwiburengerazuba bwa polytechnical ikoresha ibikoresho byo murugo mukubaka moteri yindege ya turbine disiki kurangiza neza ikizamini cya mbere cyindege, ni nubwa mbere ubwambere ceramic matrix composite rotor ifite indege. ikizamini cyo kugerageza, ariko kandi kugirango uteze imbere materique ceramic igizwe nibice kumodoka itagira abapilote (uav) / drone nini nini yo gusaba.
