SiC/SiCili ndi kukana kwambiri kutentha ndipo idzalowa m'malo mwa superalloy pakugwiritsa ntchito injini ya aero
Chiyerekezo chokwera kwambiri cha thrust-to-weight ndicho cholinga cha ma aero-injini apamwamba. Komabe, pakuwonjezeka kwa chiŵerengero cha thrust-to-weight, kutentha kwa turbine inlet kukupitirirabe, ndipo makina omwe alipo a superalloy ndi ovuta kukwaniritsa zofunikira zamainjini apamwamba. Mwachitsanzo, turbine polowera kutentha kwa injini alipo ndi thrust-to-weight ratio 10 kufika 1500 ℃, pamene pafupifupi kutentha polowera injini ndi kukankha ndi kulemera chiŵerengero cha 12 ~ 15 adzakhala upambana 1800 ℃, amene ndi kutali ndi kutentha utumiki wa superalloys ndi intermetallic mankhwala.
Pakali pano, faifi yochokera ku superalloy yokhala ndi kutentha kwabwino kwambiri imatha kufika pafupifupi 1100 ℃. Kutentha kwautumiki wa SiC/SiC kumatha kuonjezedwa mpaka 1650 ℃, komwe kumawonedwa ngati chinthu choyenera kwambiri cha injini ya aero-injini yotentha kwambiri.
Ku Europe ndi United States ndi mayiko ena otukuka oyendetsa ndege,SiC/SiCyakhala ikugwiritsidwa ntchito komanso kupanga misa m'malo oyimilira aero-injini, kuphatikiza M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 ndi mitundu ina yamainjini ankhondo / wamba; Kugwiritsa ntchito magawo ozungulira akadali pagawo lachitukuko ndi mayeso. Kafukufuku woyambira ku China adayamba pang'onopang'ono, ndipo pali kusiyana kwakukulu pakati pake ndi uinjiniya adagwiritsa ntchito kafukufuku kumayiko akunja, koma wapindulanso.
Mu Januwale 2022, mtundu watsopano wa ceramic masanjidwewo gulu ndi kumpoto chakumadzulo polytechnical yunivesite ntchito zipangizo m'nyumba kumanga ndege injini chopangira choyatsira chimbale lonse bwino anamaliza mayeso ndege yoyamba, ndi nthawi yoyamba zoweta zadothi masanjidwewo rotor okonzeka ndi ndege ndege mayeso nsanja, komanso kulimbikitsa ceramic masanjidwewo composites zigawo zikuluzikulu pa galimoto yosaulutsidwa ndege / drone.
