Abstract

Retractable, foldable and deployable structures can vary their structural shape automatically from a compact, packaged configuration to an expanded, operational configuration. The first properly engineered deployable structures were used as stabilization booms on early spacecraft. Later on, more multifaceted structures were devised for solar arrays, communication reflectors and telescopes. In other field there have been a variety of developments including retractable roofs for stadimns, foldable components for cars, portable structures for temporary shelters and exhibition display. In this project, three main themes will be discussed: concepts, working principles and mechanics of deployable structures for a satellite dish and satellite dish reflector. The design structures of a deployable satellite dish will involve the structural analysis in both two dimensional and three dimensional analyses. Such analyses would include stressstrain analysis, joints analysis, and deflection analysis, by means of manual calculations and using engineering software. The deployable and retractable satellite structure designs will be developed for the usage of space oriented satellites and also earth bound satellites, whenever there is a need in the deployable design structure. The critical aspect in this development is to develop healthy structural concepts which provide for the capability to change configuration, in other word, structure which able to produce different working geometries and also able to move from one configuration to another.
