Ibisubizo bya RF na Microwave bigezweho kuri LEO Satellite na Aerospace
Guha imbaraga amatsinda y'inyenyeri yo mu gisekuru gikurikira hamwe n'ibice byizewe cyane, byoroheje, kandi bifite ubushyuhe buhamye
Imiterere y'inganda n'ingingo z'ububabare
Itangira ry'igihe cy'Umwanya Mushya ryazanye iterambere ridasanzwe mu matsinda y'inyenyeri zo mu kirere zo mu gace ka Low Earth Orbit (LEO). Ariko,ibidukikije bigoye by'ikirereBifite imbogamizi zikomeye mu buhanga. Bitandukanye n'itumanaho ryo ku isi, indege n'ibikoresho byo mu kirere bikora mu buryo butari bwo, burangwa n'imirasire ikomeye y'ikirere, irangi rya ogisijeni ya atome, ndetse n'imbaraga zikomeye za mekanike mu gihe cyo gutangiza.
Ku bijyanye n'ibice bya RF na microwave bidakoresha ingufu, ibi bintu biremereye mu bidukikije bitegeka ko ibintu byose bigomba gukorwa neza. Abahanga bahora bahanganye n'imbogamizi z'ibikoresho. Ingingo z'ingenzi zituma ibintu birushaho kuba bibi mu kugabanya uburemere bwabyo.uburemere n'ingano y'ibikoreshobitabangamiye imikorere y'amashanyarazi. Buri garama y'inyongera ishyirwa mu kirere yongera cyane ibisabwa na lisansi n'ikiguzi cy'ubutumwa muri rusange.
Byongeye kandi, ibyogajuru bya LEO bizenguruka Isi hafi buri minota 90, bihinduka vuba hagati y'ubushyuhe bukabije bw'imirasire y'izuba n'umwijima ukonje w'igicucu cy'Isi. Ibi birema ahantu ibice bigomba kugumana ubusugire busesuye bw'umuvuduko n'ubuziranenge bw'imiterere nubwoihindagurika rikabije ry'ubushyuhe.
Ibintu by'ingenzi bibangamira ibidukikije
✦Imiterere yo gutangiza icuramye cyane:Ibice bigomba kwihanganira impanuka ikomeye y'amajwi n'iy'imashini mu gihe cyo kuzamuka kw'ingufu.
✦Gusohora imyuka ikoresheje umwuka:Ibikoresho ntibigomba kurekura ibintu bishobora guhumeka ku buso bw'urumuri cyangwa RF.
✦Umunaniro uterwa n'ubushyuhe:Kwaguka vuba no gucika intege bitera kuvunika gato mu ngingo zisoda n'imiterere y'umuraba.
Imbogamizi z'ingenzi muri RF y'indege
Imbibi zikabije za SWaP
Mu gishushanyo mbonera cya none cy’umutwaro w’ibikoresho bya satelite, SWaP (Ingano, Uburemere, n’Ingufu) ni cyo gipimo cy’ingenzi cyane. Gushyira umutwaro mu kirere birahenze cyane, akenshi bigatwara ibihumbi by’amadolari kuri kilo. Ibice bisanzwe bya RF, cyane cyane filters zifite ingufu nyinshi, multiplexers, na isolators, akenshi bikoreshwa mu muringa ukomeye cyangwa aluminiyumu nini kugira ngo bikomeze imikorere y’amashanyarazi na Q-factor.
Ikibazo kiri mu gukora ibi bice bidakora kugira ngo bihuze n'uburemere bukomeye bwa micro na nano-satellites bitabangamiye ubushobozi bwabyo bwo guhangana n'imbaraga nyinshi za RF. Gukoresha miniaturization akenshi bitera kwiyongera k'ubutaka bwo kwinjira no gukwirakwiza ubushyuhe, bigatuma habaho ikibazo gikomeye cy'ubuhanga gisaba ubuhanga bushya mu by'ibikoresho na simulation igezweho ya electromagnetic kugira ngo bikemuke.
Ihindagurika ry'ubushyuhe rikabije (-55°C kugeza +125°C)
Satelite muri LEO zihura n'ubushyuhe bukabije. Uko zizenguruka, zihura n'imirasire y'izuba itaziguye, bigatuma ubushyuhe bwo hejuru bwiyongera, hanyuma hagakurikiraho ubukonje bwinshi bw'izuba. Ibi bituma ubushyuhe bwo gukora bugomba kuba buri hagati ya -55°C na +125°C.
Ku byuma biyungurura amashanyarazi bya RF na resonators zo mu cyuho, ibi ni bibi cyane iyo bidacunzwe neza. Ibyuma birakura kandi bigatandukana bitewe n'impinduka z'ubushyuhe. Ndetse n'impinduka ntoya mu bipimo by'icyuma giyungurura amashanyarazi gishobora guhindura umurongo wacyo wo hagati, bigatera kwangirika kw'ibimenyetso, impanuka z'imiyoboro yegereye, cyangwa gutakaza burundu umurongo w'itumanaho. Kubungabunga umutekano w'amashanyarazi muri ubu bushyuhe bwa dogere 180 ni kimwe mu bibazo bikomeye mu buhanga bwa RF mu by'indege.
Ibisubizo byacu by'inyongera
Mu myaka myinshi ishize mu bushakashatsi no mu iterambere mu ikoranabuhanga rya RF/Microwave, Leader Microwave yateje imbere ubuhanga bwihariye bwo gukora ibintu byagenewe guhangana n’ibibazo bikomeye byo gushyira mu kirere.
Inzira zoroshye zo gupima no gupima aho amazi anyura
Dukoresha aloyi za aluminiyumu zigezweho n'ibikoresho byihariye bivanze kugira ngo dukore filter zacu zo mu rwego rwo hejuru. Dukoresheje uburyo bwo gutunganya neza CNC no kunoza imiterere y'imiterere, tuvanaho uburemere butari ngombwa ariko tugakomeza gukomera kw'imiterere.
Ibisubizo: Kugabanuka k'uburemere ku kigero kirenga 30% ugereranije n'imiterere gakondo, bigatuma ikiguzi cyo gutangiza gigabanuka.
Ubushyuhe Budahuye
Kugira ngo turwanye ubushyuhe buri hagati ya -55°C na +125°C, injeniyeri zacu zikoresha uburyo bwihariye bwo gupima ubushyuhe. Ibi birimo gukoresha Invar (icyuma cya nickel-iron gifite ubushobozi buke bwo kwagura ubushyuhe) hamwe n'imiterere y'ibyuma bibiri byikosora uko ubushyuhe bugenda buhinduka.
Ibisubizo: Guhagarara neza cyane ku murongo w'ingufu, bigatuma umurongo w'ingufu ugenda munsi ya 2ppm/°C, bigatuma ibimenyetso byawe biguma bifunze neza ku ntego.
Amasano yo mu kirere yizewe cyane
Kugabanya ikiguzi ntacyo bivuze niba sisitemu yananiwe mu kirere. Ibice byacu by’indege bikorerwa isesengura rikomeye ry’uburyo bwinshi bwo gukora, isuzuma ry’ubushyuhe (TVAC), no gusuzuma imitingito kugira ngo bikomeze kurangizwa no gukora neza mu gihe cyose cy’ubutumwa.
Ibisubizo: Kugabanya neza ikiguzi cyo gushyira ibintu kuri satelite mu kirere, ariko kandi bikanatuma habaho ubufatanye bw'itumanaho mu gihe kirekire mu kirere.
