Paper Abstract

Design of an extremely large optical telescope poses many technical challenges. One of these challenges includes the design of an enclosure that meets the necessary functional requirements while minimizing the financial cost. This study describes the conceptual design of the Thirty Meter Telescope enclosure. Initially, four general enclosure styles were considered including calotte, dome-shutter, carousel and co-rotating enclosure styles. Progressively detailed comparative studies were completed to evaluate the structural, mechanical, aerodynamic, thermal and operational characteristics of the candidates, and the associated capital and operational costs. As a result, the calotte enclosure was selected as the preferred configuration to carry forward through the conceptual design phase. Continuing design and analysis have brought all of the major calotte enclosure subsystems to a conceptual design level.
