FICHE TECHNIQUE<\/strong> <\/p>\n\n\n\n

Donneur d\u2019ordre: <\/strong>European Southern Observatory (ESO)<\/p>\n\n\n\n

Entrepreneur g\u00e9n\u00e9ral:<\/strong>Ace Consortium, lead by Cimolai SpA<\/strong><\/em><\/p>\n\n\n\n

L\u2019ELT<\/strong> (Extremely Large Telescope) est un t\u00e9lescope optique\/infrarouge<\/strong> dot\u00e9 d\u2019un miroir primaire de 39 m\u00e8tres de diam\u00e8tre, situ\u00e9 sur le Cerro Amazones<\/strong>, dans les Andes chiliennes, \u00e0 environ 3 000 m\u00e8tres d\u2019altitude<\/strong>. Actuellement en cours de construction, il sera le plus grand t\u00e9lescope au monde pour les observations dans la lumi\u00e8re visible et infrarouge<\/strong>. Il sera exploit\u00e9 et entretenu par l\u2019Observatoire de Paranal de l\u2019ESO<\/strong>, situ\u00e9 \u00e0 environ 20 km.<\/p>\n\n\n\n

La conception, la production, le transport sur site, l\u2019assemblage et les essais de l\u2019ELT ont \u00e9t\u00e9 confi\u00e9s au Consortium ACe, dirig\u00e9 par Cimolai SpA<\/strong>.<\/p>\n\n\n\n

L\u2019ELT sera constitu\u00e9 d\u2019une structure m\u00e9tallique de 71 m\u00e8tres de diam\u00e8tre et de 62 m\u00e8tres de hauteur. Le t\u00e9lescope, qui int\u00e8gre des solutions technologiques extr\u00eamement pr\u00e9cises et de tr\u00e8s haut niveau, sera install\u00e9 \u00e0 l\u2019int\u00e9rieur d\u2019une structure rotative en acier appel\u00e9e d\u00f4me<\/strong>. D\u2019un poids d\u2019environ 6 000 tonnes, ce d\u00f4me sera dot\u00e9 d\u2019ouvertures coulissantes, avec un diam\u00e8tre de 92 m\u00e8tres et une hauteur de 80 m\u00e8tres, ainsi que d\u2019un \u00e9cran partiellement perm\u00e9able au vent \u2014 le windscreen<\/strong>. En outre, dans la partie inf\u00e9rieure, autour du d\u00f4me, la construction d\u2019un b\u00e2timent auxiliaire<\/strong> est pr\u00e9vue. Celui-ci abritera l\u2019ensemble des locaux techniques ainsi que l\u2019entr\u00e9e principale.<\/p>\n\n\n\n

Outre les parties en acier<\/strong>, dont le poids s\u2019\u00e9l\u00e8ve \u00e0 environ 13 500 tonnes<\/strong>, le projet comprend \u00e9galement les travaux de g\u00e9nie civil, les m\u00e9canismes, les installations techniques et les finitions.<\/p>\n\n\n\n

La structure principale du t\u00e9lescope compos\u00e9e d\u2019une structure en acier d\u2019environ 4 200 tonnes, atteindra une masse rotative de 4 700 tonnes une fois int\u00e9gr\u00e9e avec les miroirs et les instruments. Cette masse se d\u00e9placera avec une pr\u00e9cision microm\u00e9trique gr\u00e2ce \u00e0 un syst\u00e8me hydrostatique, \u00e0 des moteurs lin\u00e9aires sp\u00e9ciaux et \u00e0 des encodeurs \u00e0 tr\u00e8s haute r\u00e9solution. L\u2019ensemble sera install\u00e9 sur un syst\u00e8me d\u2019isolation sismique de nouvelle conception, qui garantira une rigidit\u00e9 et une stabilit\u00e9 \u00e9lev\u00e9es pendant les phases d\u2019observation, tout en assurant, en cas de s\u00e9isme, l\u2019amortissement n\u00e9cessaire \u00e0 la protection des miroirs et instruments extr\u00eamement d\u00e9licats.<\/p>\n<\/div>\n\n\n\n\n\n
