Gukoresha ibikoresho bya SiC mubushyuhe bwo hejuru

Mu kirere no mu bikoresho by’imodoka, ibikoresho bya elegitoroniki bikunze gukora ku bushyuhe bwinshi, nka moteri yindege, moteri yimodoka, icyogajuru mu butumwa hafi yizuba, hamwe nubushyuhe bwo hejuru cyane muri satelite. Koresha ibikoresho bisanzwe bya Si cyangwa GaAs, kubera ko bidakora ku bushyuhe bwinshi cyane, bityo ibyo bikoresho bigomba gushyirwa mubushyuhe buke, hari uburyo bubiri: bumwe ni ugushyira ibyo bikoresho kure yubushyuhe bwo hejuru, hanyuma ukanyuramo kuyobora hamwe nabahuza kugirango babahuze kubikoresho bigomba kugenzurwa; Ibindi nugushira ibyo bikoresho mumasanduku ikonje hanyuma ukabishyira mubushyuhe bwo hejuru. Biragaragara, ubwo buryo bwombi bwongeramo ibikoresho byiyongera, kongera ubwiza bwa sisitemu, kugabanya umwanya uhari kuri sisitemu, no gutuma sisitemu itizera neza. Ibi bibazo birashobora gukurwaho ukoresheje ibikoresho bikora mubushyuhe bwinshi. Ibikoresho bya SIC birashobora gukoreshwa kuri 3M - cail Y idakonje mubushyuhe bwinshi.

Ibyuma bya elegitoroniki na sensor birashobora gushyirwaho imbere no hejuru ya moteri yindege zishyushye kandi bigikora muri ibi bihe bikabije, bikagabanya cyane ubwinshi bwa sisitemu no kuzamura ubwizerwe. SIC ishingiye kuri sisitemu yo kugenzura irashobora gukuraho 90% byuyobora hamwe nu muhuza ukoreshwa muri sisitemu gakondo yo kugenzura ingabo. Ibi ni ngombwa kuko ibibazo byo kuyobora no guhuza biri mubibazo bikunze kugaragara mugihe cyo kumanura indege zubucuruzi zubu.

Nk’uko isuzuma rya USAF ribigaragaza, gukoresha ibikoresho bya elegitoroniki bya SiC bigezweho muri F-16 bizagabanya ubwinshi bw’indege ku kilo amagana, bizamura imikorere n’imikorere ya lisansi, byongere ubwizerwe mu bikorwa, kandi bigabanye cyane amafaranga yo kubungabunga no gutaha. Muri ubwo buryo, ibikoresho bya elegitoroniki bya SiC na sensor birashobora kunoza imikorere yindege zubucuruzi, hamwe n’inyungu ziyongera mu bukungu muri miliyoni z’amadolari kuri buri ndege.

Mu buryo nk'ubwo, gukoresha SiC ubushyuhe bwo hejuru bwa elegitoroniki na elegitoronike muri moteri yimodoka bizafasha kugenzura neza no kugenzura umuriro, bikavamo isuku kandi neza. Byongeye kandi, sisitemu ya elegitoroniki yo kugenzura moteri ya SiC ikora neza hejuru ya 125 ° C, igabanya umubare wuyobora hamwe nu muhuza mugice cya moteri kandi ikanatezimbere igihe kirekire cyo kugenzura ibinyabiziga.

Satelite yubucuruzi yuyu munsi isaba imirasire kugirango ikwirakwize ubushyuhe butangwa na elegitoroniki y’icyogajuru, ninkinzo zo kurinda ibikoresho bya elegitoroniki ibyogajuru imirasire y’ikirere. Gukoresha ibikoresho bya elegitoroniki bya SiC mu cyogajuru birashobora kugabanya umubare w’ibiyobora hamwe n’umuhuza kimwe nubunini nubwiza bwingabo zikingira imirasire kuko ibikoresho bya elegitoroniki bya SiC ntibishobora gukora gusa mubushyuhe bwinshi, ariko kandi bifite imbaraga zo kurwanya amplitude-imirasire. Niba ikiguzi cyo kohereza icyogajuru muri orbit yisi gipimye mubwinshi, kugabanuka kwinshi ukoresheje ibikoresho bya elegitoroniki bya SiC bishobora kuzamura ubukungu no guhangana kurwego rwinganda.

Icyogajuru ukoresheje ibikoresho byo mu bwoko bwa SiC birwanya ubushyuhe bwo hejuru birashobora gukoreshwa mu gukora ubutumwa bugoye hafi y’izuba. Mu bihe biri imbere, iyo abantu bakora ubutumwa buzengurutse izuba hamwe nubuso bw’imibumbe iri mu zuba ry’izuba, ibikoresho bya elegitoroniki bya SiC bifite ubushyuhe buhanitse kandi biranga imishwarara bizagira uruhare runini mu byogajuru bikora hafi yizuba, gukoresha ibikoresho bya elegitoroniki ya SiC ibikoresho birashobora kugabanya kurinda icyogajuru nibikoresho byo gukwirakwiza ubushyuhe, Rero ibikoresho byinshi bya siyansi birashobora gushyirwaho muri buri kinyabiziga.
