SiC/SiCmuaj kev tiv thaiv cua sov zoo heev thiab yuav hloov superalloy hauv daim ntawv thov ntawm aero-engine
Lub hom phiaj ntawm cov cav aero-engine siab heev yog kom muaj qhov sib piv ntawm lub zog thawb thiab qhov hnyav siab. Txawm li cas los xij, nrog rau qhov nce ntawm qhov sib piv ntawm lub zog thawb thiab qhov hnyav, qhov kub ntawm lub cav turbine nce ntxiv, thiab cov khoom siv superalloy uas twb muaj lawm nyuaj rau ua kom tau raws li qhov xav tau ntawm cov cav aero-engine siab heev. Piv txwv li, qhov kub ntawm lub cav turbine nkag ntawm cov cav uas twb muaj lawm nrog qhov sib piv ntawm lub zog thawb thiab qhov hnyav ntawm theem 10 tau mus txog 1500 ℃, thaum qhov kub nruab nrab ntawm cov cav uas muaj qhov sib piv ntawm lub zog thawb thiab qhov hnyav ntawm 12 ~ 15 yuav tshaj 1800 ℃, uas yog deb tshaj qhov kub ntawm cov superalloys thiab cov khoom sib xyaw ua ke.
Tam sim no, cov hlau nickel-based superalloy uas muaj qhov kub zoo tshaj plaws tsuas yog ncav cuag li 1100 ℃ xwb. Qhov kub ntawm SiC/SiC tuaj yeem nce mus txog 1650 ℃, uas yog suav hais tias yog cov khoom siv zoo tshaj plaws rau kev tsim cov qauv kub aero-engine.
Hauv Tebchaws Europe thiab Tebchaws Meskas thiab lwm lub tebchaws uas tsim kev lag luam dav hlau,SiC/SiCtau siv tau tiag tiag thiab tsim ntau yam khoom siv hauv cov khoom siv aero-engine, suav nrog M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 thiab lwm hom tub rog/civil aero-engine; Kev siv cov khoom sib hloov tseem nyob rau theem kev txhim kho thiab kev sim. Kev tshawb fawb yooj yim hauv Suav teb pib qeeb qeeb, thiab muaj qhov sib txawv loj ntawm nws thiab kev tshawb fawb engineering hauv cov teb chaws txawv teb chaws, tab sis nws kuj tau ua tiav.
Thaum Lub Ib Hlis Ntuj xyoo 2022, ib hom tshiab ntawm cov khoom siv ceramic matrix composite yog los ntawm Northwest Polytechnical University siv cov ntaub ntawv hauv tsev los tsim lub cav dav hlau turbine disc tag nrho ua tiav qhov kev sim ya dav hlau thawj zaug, nws kuj yog thawj zaug uas lub rotor ceramic matrix composite hauv tsev nruab nrog lub platform sim ya dav hlau, tab sis kuj txhawb cov khoom siv ceramic matrix composites ntawm lub tsheb tsis muaj neeg tsav (uav) / drone daim ntawv thov loj.
