I-ESA ivivinya ngempumelelo i-thruster yesikhala esisha esinamandla omoya

Lapho nje i-ejensi yasemkhathini iqala iphrojekthi, ezigabeni zokuqala zephrojekthi, elinye lamaphuzu amahle okumele acaciswe kahle yilo kanye impilo ende uzoba nayo okufanayo. Yize lokhu kungabonakala kuyinto engaxazululwa ngokuhamba kwesikhathi, iqiniso ukuthi lesi silinganiso sibalulekile ngoba, ngokuya ngobude bephrojekthi, ezinye izinhlelo zokuphehla amandla noma ezinye kufanele zifakwe ukuze umthwalo kaphethiloli neminye imingcele, into ekugcineni eyekethise ukwakheka nobuciko bokuthi, lapho kufika isikhathi, iphenyo, ithunyelwe ...

Isibonelo esicacile sokuqonda lokhu kangcono kakhulu sitholakala ngokoqobo ezinkingeni i-NASA enazo nge-Kepler space telescope, izinkinga ebesikhuluma ngazo izolo ActualidadGadget futhi lokho ekugcineni kwaholela kuphrojekthi eyayinikeze imiphumela emihle kakhulu kepha leyo, ngaleso sikhathi, eyayilinganiselwa ukuthi ingahlala cishe iminyaka emithathu, isimilo esesikhule kancane kancane saze safika kulo mzuzu, lapho, cishe eminyakeni eyishumi kamuva, kuphele ngo qeda uKepler uphelelwe uphethiloli ukuwenza ungabi namsebenzi kuze kube phakade, ngaphandle kokuthi onjiniyela be-US space agency bathole isisombululo sesikhashana.

I-ESA ithuthukisa imoto entsha kagesi ekwazi ukusebenza kuma-molecule omoya

Ukuze kuzanywe ngqo ukunciphisa lezi zinhlobo zezinkinga, lezo ezihlobene nokusetshenziswa kukaphethiloli nezidingo zokugcina, i-ESA isebenze iminyaka eminingi ekwakhiweni uhlelo lokuqhutshwa kwenoveli. Ngemuva kwawo wonke lo msebenzi onzima, ekugcineni futhi njengoba kubikiwe, onjiniyela be-ESA bahlole ngempumelelo yabo i- motor entsha kagesi ekwazi ukugijima kuma-molecule omoya.

Njengoba sekubikiwe, ngokusobala futhi ngenxa yobuchwepheshe obusha obusetshenzisiwe kule njini entsha, uma isilungile, izosebenza ukuvumela iziphuphutheki, amaphenyo, imikhumbi ... ethulwa esikhaleni emishini ehlukene ukuthi ihlale isikhathi eside kakhulu . Inkinga enkulu ukuthi, ukusebenzisa lolu hlobo lwezimoto, kuyafana kumele itholakale ku-orbit ephansi yoMhlaba noma enye iplanethi, inqobo nje uma inomoya ukuze bakwazi ukusebenza.

Kuze kube manje injini isebenze kahle ekuhlolweni kwelabhorethri

Mayelana nokuhlolwa okwenziwe, njengoba kushiwo esitatimendeni esisemthethweni esikhishiwe, kusobala ukuthi sikhuluma ngakho motor ifakwe egumbini elingenalutho enekhono lokulingisa izimo ngokushoda komoya esikuthola emkhathini woMhlaba uma sesisendaweni ephakeme cishe ngamakhilomitha angama-200.

Ukusebenza kwenjini uqobo kuyinkimbinkimbi kakhulu kunalokho esingakucabanga yize, okungenani lapho kuchazwa, kungabonakala kulula kakhulu. Indlela lolu hlelo lwenoveli olusebenza ngayo lususelwa ekusetshenzisweni kwe- ama-molecule omoya. Ngokuzikhipha ngaphakathi kwemoto uqobo, lezi zikhokhiswa ngogesi futhi ngale ndlela ungakwazi sebenzisa njenge-injini ye-ion injini.

Lezi zivivinyo zikhombisile ukuthi injini yalolu hlobo kungenzeka hhayi ngemfundiso kuphela

Enye yezinzuzo ezinhle ukuthi le njini ingasetshenziswa kuphela kuma-satellite neziphenyo ezisezingeni eliphansi kangako ukuthi ingathembela ku ukunikezwa okungenamkhawulo kwama-molecule omoya okuzobanjwa lapho kudingeka. Njengoba ukwazi ukubona, sibhekene nesixazululo esingaphezu kokuthokozisayo sokuqinisekisa ukuthi izinjini ze-ion ezisetshenziswayo njengamanje ziyaphela uphethiloli ngokuhamba kwesikhathi, okuthile okusho ukuthi empeleni le mikhumbi ingahlala eminye iminyaka eminingi i-orbit.

Ukubuyela ezivivinyweni ezenziwe enjinini, kubonakala sengathi ziqale ngokuzenza zisebenze ngaphansi kwezimo ezijwayelekile, okungukuthi, ukushisa i-xenon, eyathathelwa indawo kancane kancane yinhlanganisela yomoya we-nitrogen nomoya-mpilo. Lapho sebekwazile ukuvula uhlelo besebenzisa umoya kuphela, bakwazile ukuqinisekisa ukuthi amandla kagesi asebenzisa i-propellant yasemkhathini kungenzeka ngokuphelele. Okwamanje isinyathelo esilandelayo kuzoba ukuqhubekisela phambili ukuthuthukisa nokucwengisisa i-powertrain entsha.
