Paper Abstract

The long range observation system (LROS) is based on Ritchey—chretien telescope that was designed, built and tested by ELOP. The telescope is rxunted inside a sealed external structure with large entrance window. The concept adapted in the LROS design is to divide the mechanical structures into two major assemblies: — Internal optical bench that supports the sensitive optical elennts . This bench is based on a structure made of composite material. — External body that protects and seals the internal optical structure. This structure includes large entrance window and interface flanges that can be supported on mba, tripod or a pedestal. The key to this design was to properly select and size these two structures in order to achieve the nost rigid but light—weighted structhre . This paper describes the study that was made to specify design criteria and to analyse the design according to these criteria.
