Egy ker\u00e9k \u00e9s motor n\u00e9lk\u00fcli aut\u00f3 alig \u00e9r valamit. Ugyan\u00edgy vannak bizonyos alkatr\u00e9szek, amelyeket be kell \u00e9p\u00edteni egy m\u0171holdba.<\/p>\n<\/div>\n

A legt\u00f6bb \u0171reszk\u00f6z \u00e1ramell\u00e1t\u00e1sa akkumul\u00e1torokt\u00f3l \u00e9s napelemekt\u0151l f\u00fcgg. A napelemek szil\u00edcium- vagy m\u00e1s anyagb\u00f3l k\u00e9sz\u00fclt, osty\u00e1hoz hasonl\u00f3 darabok, amelyek elektromos \u00e1ramot termelnek, amikor napf\u00e9ny \u00e9ri \u0151ket.<\/p>\n

Ha ezekb\u0151l a cell\u00e1kb\u00f3l t\u00f6bb ezer darabot nagy panelekbe kapcsolnak \u00f6ssze napelemekk\u00e9, azok egy jelent\u0151s m\u00e9ret\u0171 \u0171rhaj\u00f3t is k\u00e9pesek \u00e1rammal ell\u00e1tni. A cell\u00e1k emellett napf\u00e9ny hat\u00e1s\u00e1ra felt\u00f6ltik az akkumul\u00e1torokat. Amikor az \u0171rhaj\u00f3 \u00e1rny\u00e9kba ker\u00fcl, az akkumul\u00e1torok veszik \u00e1t az \u00e1ramell\u00e1t\u00e1st.<\/p>\n

Az \u0171rhaj\u00f3k t\u00f6bb antenn\u00e1val is rendelkeznek. Ezek \u00fagy m\u0171k\u00f6dnek, mint a f\u00fcl, \u00e9s biztos\u00edtj\u00e1k a kapcsolatot a F\u00f6lddel. Ezek k\u00f6z\u00fcl a legfontosabb egy ak\u00e1r 2 m \u00e1tm\u00e9r\u0151j\u0171 parabolaantenna, amely nagy mennyis\u00e9g\u0171 adatot \u00e9s inform\u00e1ci\u00f3t k\u00e9pes k\u00fcldeni \u00e9s fogadni.<\/p>\n

Az \u0171reszk\u00f6z \u201eagy\u00e1t\u201d a sz\u00e1m\u00edt\u00f3g\u00e9pes rendszere k\u00e9pezi. Az adatokat a sz\u00e1m\u00edt\u00f3g\u00e9p mem\u00f3ri\u00e1j\u00e1ban lehet t\u00e1rolni, vagy az antenn\u00e1k seg\u00edts\u00e9g\u00e9vel val\u00f3s id\u0151ben visszak\u00fcldeni a F\u00f6ldre.<\/p>\n

A sz\u00e1m\u00edt\u00f3g\u00e9p az \u0171rhaj\u00f3 m\u0171k\u00f6dtet\u00e9s\u00e9re vonatkoz\u00f3 utas\u00edt\u00e1sokat is t\u00e1rolja. Ez biztons\u00e1gi tartal\u00e9kot jelent arra az esetre, ha megszakadna a kapcsolat, vagy meghib\u00e1sod\u00e1s l\u00e9pne fel.<\/p>\n

Az \u0171rhaj\u00f3knak kis hajt\u00f3m\u0171vekre is sz\u00fcks\u00e9g\u00fck van az \u0171rben val\u00f3 navig\u00e1l\u00e1shoz. K\u00fcl\u00f6nb\u00f6z\u0151 t\u00edpus\u00fa hajt\u00f3m\u0171vek l\u00e9teznek.<\/p>\n

Az \u0171reszk\u00f6z\u00f6k a hajt\u00f3m\u0171vek bekapcsol\u00e1s\u00e1val fordulnak \u00e9s forognak. Ezek nagy sebess\u00e9ggel l\u00f6knek ki forr\u00f3 g\u00e1zokat az \u0171rbe. Egyes m\u0171holdak ionhajt\u00f3m\u0171vel rendelkeznek. Ezek er\u0151s elektromos mez\u0151 seg\u00edts\u00e9g\u00e9vel l\u00f6kik ki a g\u00e1zt az \u0171rbe.<\/p>","protected":false},"excerpt":{"rendered":"
