Az aut\u00f3z\u00e1s teljesen \u00faj form\u00e1t \u00f6lt\u00f6tt, amikor holland di\u00e1kok \u0171rtechnol\u00f3gi\u00e1t felhaszn\u00e1lva meg\u00e9p\u00edtett\u00e9k a Nuna-t, a 21. sz\u00e1zad t\u00f6k\u00e9letes aut\u00f3j\u00e1tst<\/sup> sz\u00e1zad.<\/p>\n<\/div>\n

A Nuna az els\u0151 helyen v\u00e9gzett a 2001-es World Solar Challenge versenyen, egy 3 010 km-es, Ausztr\u00e1li\u00e1n \u00e1t\u00edvel\u0151 versenyen, amelyen napenergi\u00e1val hajtott aut\u00f3k vettek r\u00e9szt. N\u00e9gy vil\u00e1grekordot d\u00f6nt\u00f6tt meg, 32 \u00f3ra 39 perc alatt teljes\u00edtette a t\u00e1vot, \u00e1tlagosan 91 km\/h sebess\u00e9ggel. Ezt k\u00f6vet\u0151en 2003-ban ism\u00e9t megnyerte a versenyt \u2013 ism\u00e9t minden rekordot megd\u00f6ntve.<\/p>\n

A \u00e1ramvonalas g\u00e9pnek sz\u00e1mos el\u0151nye volt. A l\u00e9gellen\u00e1ll\u00e1s cs\u00f6kkent\u00e9se \u00e9rdek\u00e9ben kialak\u00edtott k\u00fcls\u0151 burkolat \u0171rkorabeli m\u0171anyagokb\u00f3l k\u00e9sz\u00fclt, hogy k\u00f6nny\u0171, ugyanakkor er\u0151s legyen. A f\u0151testet Kevlarral meger\u0151s\u00edtett sz\u00e9nsz\u00e1lb\u00f3l k\u00e9sz\u00edtett\u00e9k, amely anyagot m\u0171holdak gy\u00e1rt\u00e1s\u00e1hoz is haszn\u00e1lnak.<\/p>\n

Az aut\u00f3 fel\u00fclet\u00e9t rendk\u00edv\u00fcl hat\u00e9kony gallium-arz\u00e9n napelemek bor\u00edtott\u00e1k, amelyeket eredetileg olyan m\u0171holdakhoz fejlesztettek ki, mint az ESA SMART-1 holdkutat\u00f3ja. A Nuna olyan kis eszk\u00f6z\u00f6ket is mag\u00e1val vitt, amelyek garant\u00e1lt\u00e1k az akkumul\u00e1tor \u00e9s a napelemek maxim\u00e1lis teljes\u00edtm\u00e9ny\u00e9t, m\u00e9g akkor is, ha az aut\u00f3 \u00e1rny\u00e9kban \u00e1llt, vagy felh\u0151s volt az id\u0151. Ezeket az eszk\u00f6z\u00f6ket sz\u00e1mos m\u0171holdon haszn\u00e1lj\u00e1k, p\u00e9ld\u00e1ul az ESA Rosetta \u00fcst\u00f6k\u00f6s-kutat\u00f3ja eset\u00e9ben is.<\/p>","protected":false},"excerpt":{"rendered":"
