Ion cav - qhov chaw tshiab horizons

Tus txiv neej mus rau hauv qhov chaw los ntawm foob pob ua ntxaij xyaw nrog kua thiab khoom roj a. Tab sis lawv kuj hu ua rau hauv lo lus nug cov hauj lwm zoo ntawm qhov chaw sib ntaus. Yuav kom ib tug kuj me me spacecraft tsawg kawg yog ib tug "catch" rau lub ntiaj teb orbit, nws yog mounted foob pob ua ntxaij impressive loj nyob rau lub sab saum toj. Thiab lub missile nws tus kheej, nyob rau hauv qhov tseeb, qhov no yog ib tug ya tank, tus tsov ntxhuav feem ntawm tus luj ntawm uas yog tshwj tseg rau roj. Thaum tag nrho cov no yog siv li kom kawg drop, on board lub nkoj tseem scanty mov.

Nyob rau hauv thiaj li tsis mus poob rov qab mus rau lub ntiaj teb, lub International chaw chaw nres tsheb tseg seb puas tsimnyog tau nws orbit mem tes dav hlau xyaw. Roj rau lawv - txog 7.5 tons - ob peb zaug ib xyoos, delivering cia li ships. Tab sis nyob rau hauv txoj kev mus Mars, yog li refuelling yog tsis xav tau. Seb nws yog lub sij hawm hais goodbye rau outdated schemes thiab them sai sai mus rau ntau tshaj ion cav?

Nyob rau hauv thiaj li yuav ua rau nws ua hauj lwm, insane cov nqi ntawm cov roj yuav tsum yuav tsum tau. Tsuas yog roj thiab hluav taws xob. Hluav taws xob no yog tsim nyob rau hauv qhov chaw los ntawm cuab lub teeb tawg los ntawm lub hnub los ntawm solar panels. Lub deb ntawm lub teeb, lub tsawg zog, ces koj yuav tau siv ntau thiab nuclear reactors. Gas nkag mus rau hauv cov thawj combustion chamber, qhov twg nws yog bombarded los ntawm electrons thiab ionized. Cov uas ua txias ntshav yog xa mus rau flare li, thiab ces - nyob rau hauv ib tug sib nqus nozzle mus disperse. Ion engine throws nws tus kheej los ntawm hlawv ntshav nrog speeds luv pa foob pob ua ntxaij xyaw. Thiab lub spacecraft twg thiaj li raug yuav tsum tau boost.
Lub hauv paus ntsiab lus ntawm cov lag luam yog yooj yim li uas koj tau sau ion engine demo nrog lawv tus kheej txhais tes. Yog hais tias lub electrode yog nyob rau hauv daim ntawv ntawm pre-balancing ntsuas cua, mounted rau lub koob ntsis thiab siv cov high voltage rau tus ntse xaus ntawm lub electrode xiav lub teeb generated rhu lawv nrog electrons. Lawv expiry yuav tsim ib tug muaj zog tshuaj tiv thaiv kev quab yuam, lub electrode pib tig.

Alas, ion xyaw muaj ib tug thrust li tu siab heev hais tias lawv muaj peev xwm tsis nres lub spacecraft ntawm tus nto ntawm lub hli, tsis hais qhov pib ntawm hauv av. Qhov no yog feem ntau kom meej meej pom hais tias peb sib piv ob tug ships, taug kev mus rau Mars. Nkoj nrog kua xyaw yuav pib davhlau tom qab ib tug ob peb feeb ntawm khaus acceleration thiab siv ib tug me ntsis tsawg lub sij hawm nyob rau hauv lub inhibition ntawm cov liab ntiaj chaw. Nkoj nrog ion xyaw yuav leeb ob lub hlis ntawm maj mam unwinding lub kauv, thiab tib lub lag luam yog tos rau nws nyob rau hauv lub cheeb tsam ntawm Mars ...
Tsis tau ion engine tau pom nws daim ntawv thov: nws yog txawm peem rau nrog ib tug series ntawm unmanned spacecraft xa mus rau long-term reconnaissance hom phiaj rau lub nyob ze thiab nyob deb planets ntawm cov hnub ci zog, lub asteroid siv.

Ion engine - tib yam vaub kib uas overtakes lub swift-footed Achilles. Siv tag nrho cov roj nyob rau hauv feeb, kua txiv uas ntsiag to engine yuav puas mus ib txhis, thiab ib daim ntawm cov hlau. Ib tug ntshav yuav khiav lag luam rau xyoo. Nws yog tau hais tias lawv yuav muab nruab nrog rau cov thawj spacecraft, uas yog sub-lub teeb ceev mus rau Alpha Centauri - lub ze tshaj plaws lub hnub qub rau lub ntiaj teb. Nws yog assumed tias lub davhlau yuav noj xwb 15-20 xyoo.
