Paper Abstract

The new generation of Extremely Large Telescopes, may require the identification of new construction technologies, in order to improve the stiffness to weight ratio of the structure, to introduce higher damping while maintaining under control the construction and maintenance costs. The identification of new construction technologies and the consequent development of the materials used, may allow to obtain a leading technological instrument able to meet also the most extreme scientific requests, and able to adapt to the new requests that might be raised along the life of the telescope. The control of the weight of the structure is extremely important also for the dimensioning of the auxiliary structures such as drives, bearings, shafts, hard stops, counterweight, stow pins, hydrostatics support systems, etc., for energy management, and for the problems related to pre-assembly, disassembly in factory and erection on site. In this preliminary study we consider a light weight floating telescope structure made of composite materials and plastic foams.
