Paper Abstract

A variety of aerodynamic studies are ongoing to assist in the development of an integrated model for the Canadian Very Large Optical Telescope (VLOT). The purpose of these studies is to investigate the characteristics of wind loading on VLOT and to produce preliminary data for input into the VLOT integrated model. We describe these various aerodynamic studies, which include analytical and statistical approximations, computational fluid dynamics analyses and wind tunnel testing. Next, we present the methods developed for coupling the wind loads into the structural dynamics module within the VLOT integrated model. Preliminary results from the computational fluid dynamics and wind tunnel studies are presented. Finally, the future plans for expanded studies and characterization of primary mirror seeing and dome seeing are outlined.
