Bude to mo\u017en\u00e9 v\u010faka kombin\u00e1cii pr\u00fadov\u00fdch a raketov\u00fdch motorov. Stargazer vzlietne pomocou tradi\u010dn\u00fdch pr\u00fadov\u00fdch motorov a akon\u00e1hle bude dos\u0165 \u010faleko od miest, prepne sa na raketov\u00e9 motory, aby vyletel do v\u00fd\u0161ky 50 kilometrov a dosiahol nadzvukov\u00fa r\u00fdchlos\u0165. T\u00e1to nadmorsk\u00e1 v\u00fd\u0161ka je viac ako \u0161tyrikr\u00e1t vy\u0161\u0161ia, ne\u017e lietaj\u00fa tradi\u010dn\u00e9 pr\u00fadov\u00e9 dopravn\u00e9 lietadl\u00e1, a cestuj\u00facim poskytne v\u00fdh\u013ead na zemsk\u00fa krivku a temn\u00fa oblohu, ktor\u00e1 je u\u017e vlastne poh\u013eadom do vesm\u00edru.

D\u00f4vod, pre\u010do mus\u00ed lietadlo letie\u0165 a\u017e takto vysoko, spo\u010d\u00edva v odpore zemskej atmosf\u00e9ry.

Dosiahnutie tohto ambici\u00f3zneho cie\u013ea v\u0161ak bude mimoriadne n\u00e1ro\u010dnou \u00falohou a bude si vy\u017eadova\u0165, aby startup Venus staval na u\u017e osved\u010den\u00fdch technol\u00f3gi\u00e1ch, ale aj vyvinul nov\u00e9: napr\u00edklad \u201eprv\u00fd raketov\u00fd motor na svete s rotuj\u00facim detona\u010dn\u00fdm motorom na kvapaln\u00e9 palivo\u201c – RDRE.<\/p>\n

Dne\u0161n\u00e9 raketov\u00e9 motory toti\u017e horia podzvukovo, \u010do by pre Stargazer nesta\u010dilo.<\/p>\n

Raketov\u00e9 motory s\u00fa vo v\u0161eobecnosti preferovan\u00e9 aj preto, \u017ee pon\u00fakaj\u00fa ove\u013ea lep\u0161\u00ed v\u00fdkon vo vy\u0161\u0161\u00edch nadmorsk\u00fdch v\u00fd\u0161kach v porovnan\u00ed s pr\u00fadov\u00fdmi motormi, preto\u017ee nevy\u017eaduj\u00fa na svoju \u010dinnos\u0165 atmosf\u00e9rick\u00fd kysl\u00edk, ktor\u00fd je vo v\u00fd\u0161ke 50 kilometrov ove\u013ea red\u0161\u00ed ako pri povrchu.<\/p>\n

V okt\u00f3bri 2022 sa Venus stala prvou spolo\u010dnos\u0165ou na svete, ktor\u00e1 vytvorila \u201ekvapaln\u00e9 paliv\u00e1 skladovate\u013en\u00e9 pri izbovej teplote\u201c na prev\u00e1dzku v RDRE.<\/p>\n Foto: Venus Aerospace\n

Spolo\u010dnos\u0165 pre Business Insider potvrdila, \u017ee sa tie\u017e zaoberala obavami z mikrometeoritov v atmosf\u00e9re. Pouk\u00e1zala pritom na Blue Origin a Virgin Galactic ako pr\u00edklady \u201everejn\u00e9ho in\u017einierstva, ktor\u00e9 ukazuj\u00fa, ako by to zvl\u00e1dli\u201c.<\/p>\n

Startup u\u017e dnes informuje, \u017ee letenky nebude mo\u017en\u00e9 udr\u017ea\u0165 lacn\u00e9. Tvrd\u00ed, \u017ee \u0161t\u00fadie ukazuj\u00fa, \u017ee cestovn\u00e9 za hypersonick\u00e9 cestovanie bude minim\u00e1lne dvakr\u00e1t a\u017e p\u00e4\u0165kr\u00e1t vy\u0161\u0161ie ako cena letenky prvej triedy. Aktu\u00e1lne ceny leteniek v prvej triede u dopravcov ako Emirates a Singapore Airlines sa pohybuj\u00fa v desiatkach tis\u00edc dol\u00e1rov. V\u00fdskum Venus odhalil, \u017ee obchodn\u00ed cestuj\u00faci s\u00fa ochotn\u00ed zaplati\u0165 viac ako be\u017en\u00fa cenu letenky prvej triedy, ak dok\u00e1\u017eu skr\u00e1ti\u0165 lety na dlh\u00e9 vzdialenosti len na jednu hodinu.<\/p>\n

Ani to by ale nemuselo by\u0165 prek\u00e1\u017ekou v populariz\u00e1cii. Typick\u00fd l\u00edstok na Concorde st\u00e1l koncom 90. rokov 6000 dol\u00e1rov (jednosmerne). Naj\u010dastej\u0161\u00edm pasa\u017eierom Concordu je Fred Finn, ktor\u00fd letel na nadzvukovom lietadle 718-kr\u00e1t a a\u017e do odchodu lietadla do d\u00f4chodku v roku 2003 minul na tieto letenky vy\u0161e 2,5 mili\u00f3na dol\u00e1rov (v s\u00fa\u010dasnosti asi 4,4 mili\u00f3na dol\u00e1rov).<\/p>\n

Spolo\u010dnos\u0165\u00a0 Venus pritom uzn\u00e1va, \u017ee aj napriek niektor\u00fdm legislat\u00edvnym \u00faspechom m\u00e1 pred sebou e\u0161te ve\u013emi dlh\u00fa cestu, ktor\u00e1 bude obn\u00e1\u0161a\u0165 nielen propag\u00e1ciu technol\u00f3gie, ale v prvom rade jej d\u00f4sledn\u00e9 otestovanie a zabezpe\u010denie vysokej bezpe\u010dnosti. Venus pre Insider dod\u00e1va, \u017ee m\u00e1 v \u00famysle predstavi\u0165 Stargazer v 30. rokoch.<\/p>\n
