Abstract

The NNTT is being designed as an array of four telescopes, each 7.5 meters in primary diameter, on a common mounting, phased in the infrared, and able to produce 0.25 arcsecond images. Rapid changeover from combined beam to individual telescope operation is required. To accomplish this, a mechanical configuration employing exchangeable top-end optics modules has been designed. Early results of structural analysis are presented. Structural provisions for driving the telescope are discussed. To meet imaging goals, we conclude that careful structural design plus active position control of the optics is necessary and feasible.
