Abstract:

Due theoretical, design and experimental studies related with the development of large deployable antenna reflectors have already been carried out for quite a long time, this area still remains of lively interest and has good application prospects. In the paper we describe the invention of new design of deployable ring structure for symmetric and asymmetric (with circular and elliptical apertures) radio telescopes. The novelty consists in that new engineering and technological effects we obtained by synthesis of two conical pantograph systems and whole rod structure consists cylindrical and sliding hinges only.
