Space disks - kūpono a wikiwiki loa

I kēia manawa, ʻo ka mea wikiwiki loa i hoʻokuʻu ʻia e ke kanaka ma ka lewa, ʻo ia ka Voyager probe, i hiki ke hoʻolalelale i 17 km / s me ka hoʻohana ʻana i nā mea hoʻolaha gravity mai Jupiter, Saturn, Uranus a me Neptune. He mau kaukani manawa lohi kēia ma mua o ka mālamalama, ʻehā makahiki a hiki i ka hōkū kokoke loa i ka Lā.

Hōʻike ka hoʻohālikelike ma luna nei i ka wā e pili ana i ka ʻenehana propulsion i ka huakaʻi lewa, he nui kā mākou e hana inā makemake mākou e hele i kahi ma waho o nā kino kokoke loa o ka ʻōnaehana solar. A he lōʻihi loa kēia mau huakaʻi kokoke. ʻO 1500 mau lā o ka lele ʻana i Mars a hoʻi, a me ka hoʻonohonoho ʻana i ka honua maikaʻi, ʻaʻole ia he mea hoʻoikaika nui.

Ma nā huakaʻi lōʻihi, ma kahi o nā kaʻa nāwaliwali loa, aia kekahi mau pilikia ʻē aʻe, no ka laʻana, me nā lako, nā kamaʻilio, nā kumuwaiwai ikehu. ʻAʻole paʻa nā panela solar i ka wā e mamao aku ai ka lā a i ʻole nā ​​hōkū ʻē aʻe. Hoʻohana ʻia nā reactor nuklea me ka piha piha no kekahi mau makahiki wale nō.

He aha nā mea hiki a me nā manaʻo no ka hoʻomohala ʻana i ka ʻenehana no ka hoʻonui a hāʻawi ʻana i nā wikiwiki kiʻekiʻe i kā mākou mokulele? E nānā kākou i nā hoʻonā i loaʻa a me nā mea i hiki ke hiki i ka ʻepekema a me ka ʻepekema, ʻoiai ʻoi aku ka manaʻo.

I kēia manawa: kemika a me ka ion rockets

I kēia manawa, hoʻohana mau ʻia ka propulsion kemika ma kahi ʻano nui, e like me ka wai hydrogen a me nā rockets oxygen. ʻO ka wikiwiki kiʻekiʻe e hiki ke hoʻokō ʻia e hoʻomaikaʻi iā lākou ma kahi o 10 km / s. Inā hiki iā mākou ke hana i ka hapa nui o nā hopena umekaumaha ma ka ʻōnaehana solar, me ka lā ponoʻī, hiki i kahi moku me kahi ʻenekini rocket kemika ke piʻi aku ma mua o 100 km/s. ʻO ka wikiwiki haʻahaʻa o Voyager ma muli o ka ʻoiaʻiʻo o kāna pahuhopu ʻaʻole e hoʻokō i ka wikiwiki kiʻekiʻe. ʻAʻole hoʻi ʻo ia i hoʻohana i ka "afterburner" me nā ʻenekini i ka wā o nā mea kōkua umekaumaha honua.

ʻO nā thrusters Ion nā ʻenekini rocket kahi i wikiwiki ai nā ion ma muli o ka pilina electromagnetic ka mea lawe. He ʻumi paha ʻoi aku ka maikaʻi ma mua o nā ʻenekini rocket kemikal. Hoʻomaka ka hana ma ka ʻenekini i ka waena o ke kenekulia i hala. I nā mana mua, ua hoʻohana ʻia ka uahu mercury no ka hoʻokele. I kēia manawa, hoʻohana nui ʻia ka xenon noble gas.

ʻO ka ikehu e hoʻokuʻu ana i ke kinoea mai ka ʻenekini mai kahi kumu waho (nā paneli lā, kahi reactor e hoʻoulu ai i ka uila). Huli nā ʻātoma kinoea i mau iona maikaʻi. A laila wikiwiki lākou ma lalo o ka mana o ka uila a i ʻole ka magnetic, hiki i ka wikiwiki a hiki i 36 km / s.

ʻO ka wikiwiki kiʻekiʻe o ka mea i hoʻokuʻu ʻia e alakaʻi i ka ikaika hoʻokuʻu kiʻekiʻe i kēlā me kēia hui nui o ka mea i hoʻokuʻu ʻia. Eia naʻe, ma muli o ka mana haʻahaʻa o ka ʻōnaehana hoʻolako, liʻiliʻi ka nui o ka mea lawe i hoʻokuʻu ʻia, e hōʻemi ana i ka pahu o ka rocket. ʻO kahi moku i lako me ia ʻenekini e neʻe me ka wikiwiki iki.

E ʻike ʻoe i ka hoʻomau o ka ʻatikala ma ka pukana o Mei o ka makasina

VASIMR ma ka mana piha
