Emkhathini nasezintweni zezimoto, izinto zikagesi zivame ukusebenza emazingeni okushisa aphezulu, njengezinjini zezindiza, izinjini zezimoto, imikhumbi-mkhathi emishini eseduze nelanga, kanye nemishini enezinga eliphezulu lokushisa kumasathelayithi. Sebenzisa amadivaysi ajwayelekile e-Si noma e-GaAs, ngoba awasebenzi emazingeni okushisa aphakeme kakhulu, ngakho-ke lawa madivaysi kufanele abekwe endaweni yokushisa ephansi, kunezindlela ezimbili: enye iwukubeka lawa madivaysi kude nokushisa okuphezulu, bese ngokusebenzisa umkhondo nezixhumi ukuze uwaxhume kudivayisi okufanele ilawulwe; Okunye ukufaka le mishini ebhokisini lokupholisa bese uyibeka endaweni enezinga lokushisa eliphezulu. Ngokusobala, zombili lezi zindlela zengeza imishini eyengeziwe, ukwandisa ikhwalithi yesistimu, ukunciphisa isikhala esitholakalayo ohlelweni, futhi kwenze uhlelo lungathembeki kangako. Lezi zinkinga zingaqedwa ngokusebenzisa ngokuqondile amadivaysi asebenza emazingeni okushisa aphezulu. Amadivaysi e-SIC angasebenza ngokuqondile ku-3M — cail Y ngaphandle kokupholisa ezingeni lokushisa eliphezulu.
Izinto zikagesi ze-SiC nezinzwa zingafakwa ngaphakathi nangaphezulu kwezinjini zezindiza ezishisayo futhi zisasebenza ngaphansi kwalezi zimo zokusebenza ezidlulele, kunciphisa kakhulu ingqikithi yesistimu futhi kuthuthukise ukwethembeka. Uhlelo lokulawula okusatshalaliswa olusekelwe ku-SIC lungaqeda u-90% womkhondo nezixhumi ezisetshenziswa ezinhlelweni zokulawula izihlangu ze-elekthronikhi zendabuko. Lokhu kubalulekile ngoba izinkinga zomthofu nezixhumi ziphakathi kwezinkinga ezivame ukuhlangatshezwana nazo ngesikhathi sokungasebenzi ezindizeni zezentengiselwano zanamuhla.
Ngokokuhlola kwe-USAF, ukusetshenziswa kwezinto zikagesi ezithuthukisiwe ze-SiC ku-F-16 kuzonciphisa isisindo sendiza ngamakhulu amakhilogremu, kuthuthukise ukusebenza nokusebenza kahle kukaphethiloli, kukhuphule ukwethembeka kokusebenza, futhi kunciphise kakhulu izindleko zokuyilungisa kanye nesikhathi sokungasebenzi. Ngokufanayo, izinto zikagesi ze-SiC nezinzwa zingathuthukisa ukusebenza kwamajeli ezentengiselwano, futhi kubikwe inzuzo eyengeziwe yezomnotho ezigidini zamadola endizeni ngayinye.
Ngokufanayo, ukusetshenziswa kwezinzwa ze-elektroniki ze-SiC zokushisa okuphezulu kanye ne-electronics ezinjini zezimoto kuzovumela ukuqapha nokulawula ukusha okungcono, okuholela ekushiseni okuhlanzekile nokusebenza kahle. Ngaphezu kwalokho, isistimu yokulawula i-electronic injini ye-SiC isebenza kahle ngaphezu kuka-125 ° C, okunciphisa inani lomkhondo nezixhumi endaweni yenjini futhi ithuthukise ukwethembeka kwesikhathi eside kwesistimu yokulawula imoto.
Amasathelayithi ezentengiselwano anamuhla adinga ama-radiator ukuthi asuse ukushisa okukhiqizwa izinto zikagesi zomkhumbi-mkhathi, kanye nezihlangu zokuvikela izinto zikagesi zomkhumbi-mkhathi emisebeni yasemkhathini. Ukusetshenziswa kwe-SiC electronics kumkhumbi-mkhathi kunganciphisa inani lomkhondo nezixhumi kanye nosayizi nekhwalithi yezihlangu zemisebe ngoba i-SiC electronics ayikwazi ukusebenza kuphela emazingeni okushisa aphezulu, kodwa futhi ibe nokumelana okuqinile kwe-amplitude-radiation. Uma izindleko zokwethula isathelayithi ku-Earth orbit zikalwa ngobuningi, ukuncishiswa kwenqwaba kusetshenziswa i-SiC electronics kungathuthukisa umnotho kanye nokuncintisana kwemboni yesathelayithi.
Imikhumbi-mkhathi esebenzisa amadivaysi e-SiC abamba ukushisa okuphezulu ukumelana nemisebe ingase isetshenziselwe ukwenza imisebenzi eyinselele ezungeza isimiso sonozungezilanga. Esikhathini esizayo, lapho abantu benza imisebenzi ezungeze ilanga kanye nobuso bamaplanethi ohlelweni sonozungezilanga, izinto zikagesi ze-SiC ezinezinga eliphezulu lokushisa eliphezulu nezici zokumelana nemisebe zizodlala indima ebalulekile kumkhumbi-mkhathi osebenza eduze nelanga, ukusetshenziswa kwemishini kagesi ye-SiC kunganciphisa ukuvikelwa kwemikhumbi-mkhathi kanye nemishini yokuchitha ukushisa, Ngakho-ke amathuluzi amaningi esayensi angafakwa emotweni ngayinye.
