Ion injini - isikhala khathizwe entsha

I Umuntu uye emkhathini ngokusebenzisa rocket izinjini nge zokubasa liquid okuqinile. Kodwa wangabaza ukusebenza indiza emkhathini. Ukuze a elincane mkhathi okungenani "catch" I- orbit eMhlabeni, it is agibele amahhashi rocket usayizi umxhwele phezulu. Futhi lo missile uqobo, eqinisweni, lokhu ithangi ezindizayo, share sengonyama isisindo zazo kugcinelwe nophethiloli. Lapho bonke selisetshenzisiwe iconsi lokugcina, emkhunjini uhlala supply mancane.

Ukuze ukuba angaweli emuva Earth, -International Space Station njalo kuphakamisa yayo orbit ishayela jet izinjini. Okokhelekayo ngabo - angaba ngu-7.5 - izikhathi eziningana ngonyaka, ekuletheni imikhumbi ezenzakalelayo. Kodwa endleleni eya Mars, ngakho refueling is akulindelekile. Noma ngabe isikhathi ngithi goodbye kuya izikimu yisikhathi futhi banake okuthuthukile ion injini?

Ukuze-ke umsebenzi, amanani uyahlanya uphethiloli kuzodingeka. Kuphela igesi nogesi. Ugesi ikhiqizwa isikhala ukushayeka emisebeni ukukhanya okuvela elangeni akhishwa ama-solar panel. I kude ukukhanya, amandla kancane, ngakho kufanele usebenzise kakhudlwana futhi Kuneziteshi zamandla enuzi. Negesi ihlinzekwa ku esiyinhloko omlilo egumbini, lapho ukujikijelwa ngu-electron futhi ionized. I kwaphumela plasma abandayo ithunyelwa kukhuphukele emakhaleni ami, bese - ku umlomo wombhobho kazibuthe ukuhlakazeka. Ion injini uziphonsa unganqotshwa plasma nge ngesivinini ayitholakali ezivamile rocket izinjini. Futhi mkhathi Ufika kudingeka umfutho.
Umgomo we operation kunjalo elula ukuthi ungakwazi ukuqoqa ion injini demo ngezandla zabo. Uma electrode kuyinto ngesimo pre-sekulinganisa vane, ogibele ithiphu inaliti isicelo voltage okusezingeni eliphezulu emaceleni abukhali we electrode livela ilambu elikuhlaza elakhiwe ukubahlwitha ne-electron. kwesikhathi sabo izodala ababuthakathaka ukuphendula amandla, electrode iqala ukujikisa.

Maye, ion izinjini abe wagxila dabukisa ukuthi abayeki mkhathi ebusweni inyanga, ingasaphathwa kuqale phansi. Lokhu kubonakala ngokucacile kubonakala uma siqhathanisa imikhumbi emibili, baya Mars. Umkhumbi ne izinjini ketshezi uzoqala indiza emva kwamaminithi ambalwa ukusheshisa okukhulu ukuchitha isikhathi kancane kancane on the okusithiyayo of Iplanethi Ebomvu. Umkhumbi nge ion izinjini ukuphuthumisa izinyanga ezimbili kancane unwinding le Kuvunguza, futhi ngendlela efanayo ulinde kuye eduze Mars ...
Nokho injini ion ithole isicelo yayo: ifakwe uchungechunge mkhathi unmanned ethunyelwe eside kwesimo endaweni mission amaplanethi eduze futhi engangeneki sonozungezilanga, ibhande elisemkhathini.

Ion injini - ufudu efanayo fumana asheshe ezinezinyawo Achilles. Ukusebenzisa sonke fuel ngamaminithi, uketshezi kuba injini buthule iba engenamsebenzi phakade, futhi isiqeshana yensimbi. A-plasma ongasebenza iminyaka. Kungenzeka ukuthi uzobe ifakwe mkhathi kuqala, okuyinto sub-ukukhanya isivinini sokuhamba uya Alpha Centauri - inkanyezi eliseduze Earth. Kusolwa ukuthi indiza kuzothatha iminyaka 15-20 kuphela.
