SiC/SiCmuaj kev tiv thaiv kub zoo heev thiab yuav hloov superalloy hauv kev siv aero-engine
High thrust-rau-hnyav piv yog lub hom phiaj ntawm advanced aero-engines. Txawm li cas los xij, nrog qhov nce ntawm qhov sib zog-rau-qhov hnyav, turbine inlet kub nce ntxiv, thiab cov khoom siv superalloy uas twb muaj lawm yog qhov nyuaj kom ua tau raws li cov kev xav tau ntawm cov tshuab aero-kho siab heev. Piv txwv li, turbine inlet kub ntawm cov cav uas twb muaj lawm nrog thrust-rau-qhov hnyav piv ntawm qib 10 tau mus txog 1500 ℃, thaum qhov nruab nrab inlet kub ntawm cov cav nrog thrust-rau-qhov hnyav piv ntawm 12 ~ 15 yuav tshaj 1800 ℃, uas yog deb dhau qhov kev pabcuam kub ntawm superalloys thiab intermetallic compounds.
Tam sim no, cov nickel-based superalloy nrog cov cua sov zoo tshaj plaws tuaj yeem ncav cuag li 1100 ℃. Qhov kev pabcuam kub ntawm SiC / SiC tuaj yeem nce mus rau 1650 ℃, uas yog suav tias yog qhov zoo tshaj plaws aero-engine kub kawg qauv khoom.
Hauv Tebchaws Europe thiab Tebchaws Meskas thiab lwm lub tebchaws tsim dav hlau,SiC/SiCtau siv tswv yim thiab ntau lawm hauv aero-engine chaw nres tsheb, suav nrog M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 thiab lwm hom tub rog / pej xeem aero-engines; Daim ntawv thov ntawm cov khoom sib hloov yog tseem nyob rau theem ntawm kev txhim kho thiab kev sim. Cov kev tshawb fawb hauv Suav teb tau pib maj mam, thiab muaj qhov sib txawv loj ntawm nws thiab engineering siv kev tshawb fawb nyob rau txawv teb chaws, tab sis nws kuj tau ua tiav.
Thaum Lub Ib Hlis Ntuj xyoo 2022, ib yam tshiab ntawm ceramic matrix composite yog los ntawm Northwestern polytechnical tsev kawm ntawv siv cov khoom siv hauv tsev los tsim lub cav cav turbine disc tag nrho ua tiav ntawm thawj lub davhlau sim, nws kuj yog thawj zaug hauv domestic ceramic matrix composite rotor nruab nrog huab cua ya. xeem platform, tab sis kuj txhawb cov ceramic matrix composites Cheebtsam ntawm unmanned aerial tsheb (uav) / drone loj-scale daim ntawv thov.
