<\/p>\nO analiz\u0103 recent\u0103 publicat\u0103 de publica\u021bia Welt, bazat\u0103 pe cercet\u0103rile a doi oameni de \u0219tiin\u021b\u0103 de la Massachusetts Institute of Technology (MIT), ofer\u0103 detalii \u00eengrijor\u0103toare despre tehnologia din spatele rachetei de croazier\u0103 ruse\u0219ti \u201eBurevestnik\u201d. Calificat\u0103 drept o \u201earm\u0103-minune\u201d cu raz\u0103 de ac\u021biune teoretic nelimitat\u0103, aceasta prezint\u0103 riscuri majore de contaminare chiar \u00eenainte de a-\u0219i atinge \u021binta.<\/p>\n

Pentru a simplifica designul, proiectan\u021bii ru\u0219i ar fi renun\u021bat complet la structurile de izolare \u0219i la sistemele de r\u0103cire specifice centralelor nucleare civile.<\/p>\n
\t\t\tCum func\u021bioneaz\u0103 propulsia rachetei<\/p>\n
Conform exper\u021bilor cita\u021bi, rachetea folose\u0219te un motor cu reac\u021bie cu ciclu direct. Diferen\u021ba fundamental\u0103 fa\u021b\u0103 de un motor conven\u021bional const\u0103 \u00een sursa de c\u0103ldur\u0103: aerul care intr\u0103 \u00een turbin\u0103 nu este \u00eenc\u0103lzit prin arderea kerosenului, ci direct de energia degajat\u0103 de un reactor nuclear de mici dimensiuni.<\/p>\n
Datele tehnice analizate pe baza imaginilor \u0219i clipurilor video disponibile indic\u0103 urm\u0103toarele caracteristici:<\/p>\n
-Dimensiuni: lungime de aproximativ 9,5 metri \u0219i o anvergur\u0103 a aripilor de circa 5,6 metri.<\/p>\n
-Vitez\u0103: evolueaz\u0103 la viteze subsonice mari, similare rachetelor de croazier\u0103 clasice.<\/p>\n
-Putere: reactorul intern trebuie s\u0103 genereze 4,3 megawa\u021bi \u00een regim de croazier\u0103 \u0219i peste 15 megawa\u021bi \u00een timpul manevrelor sau al ascensiunii.<\/p>\n
\u201eAdev\u0103rata capabilitate a acestui sistem nu rezid\u0103 \u00een vitez\u0103, ci \u00een autonomie. Spre deosebire de rachetele conven\u021bionale, Burevestnik nu este limitat\u0103 de combustibil \u0219i poate r\u0103m\u00e2ne \u00een aer ore sau chiar zile \u00eentregi \u00eenainte de a lovi o \u021bint\u0103\u201d, noteaz\u0103 raportul.<\/p>\n
\t\t\tRiscurile de mediu \u0219i \u201ereactorul deschis\u201d<\/p>\n
Speciali\u0219tii catalogheaz\u0103 acest design drept unul iresponsabil. \u00cen lipsa unui schimb\u0103tor de c\u0103ldur\u0103 care s\u0103 izoleze fluxul de aer de miezul radioactiv, aerul exterior trece direct prin zona activ\u0103 a reactorului pentru a fi \u00eenc\u0103lzit \u0219i evacuat prin partea posterioar\u0103.<\/p>\n

Acest proces duce \u00een mod inevitabil la formarea de izotopi radioactivi care sunt elibera\u021bi direct \u00een atmosfer\u0103 \u00een timpul zborului. Chiar \u0219i \u00een eventualitatea \u00een care racheta nu ar purta o \u00eenc\u0103rc\u0103tur\u0103 militar\u0103 nuclear\u0103, pr\u0103bu\u0219irea sau utilizarea ei ar provoca o contaminare radioactiv\u0103 sever\u0103 a mediului \u00een zona de impact.<\/p>\n
Cele mai mari riscuri pe termen scurt r\u0103m\u00e2n \u00eens\u0103 legate de faza de testare, eventualele accidente logistice sau opera\u021biunile de recuperare a epavelor.<\/p>\n
Rusia a efectuat anterior un test al rachetei Burevestnik de pe arhipelagul Arctic Noua Zemlea. Potrivit surselor militare, racheta ar fi parcurs o distan\u021b\u0103 semnificativ\u0103 \u00een cadrul testului.<\/p>\n","protected":false},"excerpt":{"rendered":"O analiz\u0103 recent\u0103 publicat\u0103 de publica\u021bia Welt, bazat\u0103 pe cercet\u0103rile a doi oameni de \u0219tiin\u021b\u0103 de la Massachusetts…\n","protected":false},"author":2,"featured_media":213368,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[12],"tags":[32,33,31,416,36,37,27,74,34,35,25,59856,59857,41,40,38,39,45,26,28,29,30,71,72,73],"class_list":["post-213367","post","type-post","status-publish","format-standard","has-post-thumbnail","category-international","tag-breaking-news","tag-breakingnews","tag-cele-mai-populare-subiecte","tag-cercetatori","tag-featured-news","tag-featurednews","tag-headlines","tag-international","tag-latest-news","tag-latestnews","tag-news","tag-racheta-burevesnik","tag-reactor-nuclear-deschis","tag-ro","tag-romana","tag-romania","tag-romanian","tag-rusia","tag-stiri","tag-titluri","tag-top-stories","tag-topstories","tag-world","tag-world-news","tag-worldnews"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ro\/116800728209831185","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts\/213367","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/comments?post=213367"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts\/213367\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/media\/213368"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/media?parent=213367"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/categories?post=213367"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/tags?post=213367"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
