Paper Abstract

Status of the Feasibility Study of E-ELT, the ESO 42 m Extreme Large Telescope, with emphasis on the Dome architecture and erection. The Dome is a hemispherical shape concept servomechanism 86 m high, with an external diameter of 108 m and a 45 m wide Observing Slit. Such dimensions require the application of big structure technologies (like stadium, hangar etc), in order to comply with manufacturing, transport and assembly constrains. The mentioned technology must be fitted with mechanical and control system constrains required by this kind of servo-system. Mechanisms inside the Dome must be sufficiently light and stiff, and composite materials meet the above mentioned requirements. The management of the whole mass is extremely important for the services and power consumption. This paper describes how the above mentioned problems were handled during the E-ELT Dome Feed study.
