Kwi-aerospace kunye nezixhobo zeemoto, i-electronics idla ngokusebenza kumaqondo obushushu aphezulu, njengeenjini zeenqwelo-moya, ii-injini zeenqwelo-moya, iziphekepheke ezikwimishini ekufutshane nelanga, kunye nezixhobo zobushushu obuphezulu kwiisathelayithi. Sebenzisa izixhobo eziqhelekileyo ze-Si okanye ze-GaAs, kuba azisebenzi kumaqondo aphezulu kakhulu, ngoko ke ezi zixhobo kufuneka zibekwe kwindawo yokushisa ephantsi, kukho iindlela ezimbini: enye kukubeka ezi zixhobo kude nobushushu obuphezulu, kwaye emva koko ikhokelela kunye nezihlanganisi ukuba zidibanise kwisixhobo esiza kulawulwa; Enye kukubeka ezi zixhobo kwibhokisi yokupholisa uze uzibeke kwindawo yobushushu obuphezulu. Ngokucacileyo, zombini ezi ndlela zongeza izixhobo ezongezelelweyo, ukwandisa umgangatho wenkqubo, ukunciphisa indawo ekhoyo kwinkqubo, kwaye yenza inkqubo ingathembeki. Ezi ngxaki zinokupheliswa ngokusebenzisa ngokuthe ngqo izixhobo ezisebenza kumaqondo okushisa aphezulu. Izixhobo ze-SIC zinokuqhutywa ngokuthe ngqo kwi-3M - i-cail Y ngaphandle kokupholisa kwiqondo lokushisa eliphezulu.
I-electronics ye-SiC kunye ne-sensors inokufakwa ngaphakathi nangaphezulu kweenjini zeenqwelomoya ezishushu kwaye zisasebenza phantsi kwezi meko zinzima zokusebenza, ukunciphisa kakhulu ubunzima benkqubo epheleleyo kunye nokuphucula ukuthembeka. Inkqubo yolawulo esasazwayo esekelwe kwi-SIC inokuphelisa i-90% yesikhokelo kunye nezihlanganisi ezisetyenziswa kwiinkqubo zolawulo lwekhaka lombane. Oku kubalulekile kuba iingxaki zokukhokela kunye nekhonkco ziphakathi kwezona ngxaki zixhaphakileyo kuhlangatyezwana nazo ngexesha lokuphumla kwiinqwelomoya zorhwebo zanamhlanje.
Ngokovavanyo lwe-USAF, ukusetyenziswa kwe-elektroniki ye-SiC ephezulu kwi-F-16 kuya kunciphisa ubunzima benqwelomoya ngamakhulu eekhilogram, kuphuculwe ukusebenza kunye nokusebenza kakuhle kwamafutha, ukwandisa ukuthembeka kokusebenza, kunye nokunciphisa kakhulu iindleko zokulondoloza kunye nexesha lokunciphisa. Ngokufanayo, i-electronics ye-SiC kunye ne-sensor inokuphucula ukusebenza kweejeli zorhwebo, kunye neenzuzo ezongezelelweyo zezoqoqosho ezichazwe kwizigidi zeedola ngenqwelomoya.
Ngokufanayo, ukusetyenziswa kwe-SiC yobushushu obuphezulu bezinto zombane ze-elektroniki kunye ne-elektroniki kwiinjini zeemoto kuya kwenza ukuba kube lula ukubeka iliso kunye nokulawula ukutsha, okukhokelela ekutshiseni okucocekileyo kunye nokusebenza kakuhle. Ngaphezu koko, inkqubo ye-injini ye-SiC yokulawula i-electronic system isebenza kakuhle ngaphezu kwe-125 ° C, eyanciphisa inani leekhokelo kunye nezixhumi kwi-injini ye-injini kunye nokuphucula ukuthembeka kwexesha elide lenkqubo yokulawula isithuthi.
Iisathelayithi zorhwebo zanamhlanje zifuna iiradiyetha ukuba zibususe ubushushu obuveliswa zizixhobo zombane zesiphekepheke, kunye nezikhuselo zokukhusela izixhobo zombane zesiphekepheke kwimitha yelanga. Ukusetyenziswa kombane we-SiC kwiziphekepheke kunokunciphisa inani leenkokeli kunye nezihlanganisi kunye nobukhulu kunye nomgangatho wezikhuselo zemitha kuba ii-elektroniki ze-SiC azinakusebenza kuphela kumaqondo obushushu aphezulu, kodwa zikwanazo noxhathiso oluluqilima lwe-amplitude-radiation. Ukuba ixabiso lokuphehlelela isathelayithi kwi-Earth orbit ilinganiswa ngobuninzi, ukuncitshiswa kobuninzi kusetyenziswa i-SiC electronics kunokuphucula uqoqosho kunye nokhuphiswano lweshishini lesathelayithi.
Iziphekepheke ezisebenzisa izixhobo ze-SiC ezikwaziyo ukumelana nobushushu obuphezulu zinokusetyenziselwa ukwenza imisebenzi enzima kakhulu kwiplanethi yelanga. Kwixesha elizayo, xa abantu benza imisebenzi ejikeleze ilanga kunye nomphezulu weeplanethi kwinkqubo yelanga, izixhobo zombane ze-SiC ezinobushushu obuphezulu kunye neempawu zokumelana nemitha ziya kudlala indima ephambili kwi-spacecraft esebenza kufuphi nelanga, ukusetyenziswa kwe-SiC electronic. izixhobo zinokunciphisa ukukhuselwa kwesiphekepheke kunye nezixhobo zokuchitha ubushushu, Ngoko ke izixhobo zenzululwazi ezingakumbi zinokufakwa kwisithuthi ngasinye.
