New constructions of lightweight deployable reflectors

Creation of large size, lightweight, rigid and precision reflectors is the problem that still remains in the field of space antennas. In recent years, a voluminous work has been being conducted jointly by the European Space Agency, Munich Technical University and Georgian Technical University aiming at finding out a new structural design. The structures of the rings having a new design circular double pantograph, conical V-fold bars, unfolding springs and electrical motors, and of the flexible, geometrically unchangeable center have been elaborated and theoretically and experimentally studied within the scope of the work. The researches and tests revealed pros and cons of the new constructions. In their entirety, the structures are rigid, precision, lightweight and are capable of controlling and managing the transforming processes
