Imirima yo gusaba ya SiC / SiC

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 bwinjiza bwa moteri zisanzwe zifite igipimo cyo guterera-uburemere bwurwego rwa 10 cyageze kuri 1500 ℃, mugihe impuzandengo yubushyuhe bwa moteri ya moteri ifite igipimo cya 12 ~ 15 kizarenga 1800 ℃, kikaba kirenze kure ubushyuhe bwa serivisi bwa superalloys hamwe n’ibintu bivangwa na intermetallic.

Kugeza ubu, nikel ishingiye kuri superalloy hamwe nubushyuhe bwiza irashobora kugera kuri 1100 gusa. Ubushyuhe bwa serivisi ya SiC / SiC burashobora 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 ibikoresho byo kugerageza indege, ariko kandi ikanateza imbere materique ceramic igizwe nibinyabiziga bitagira abapilote (uav) / drone nini.
