Prospects of Increasing the Dimensional Stability and the Weight Efficiency of Mirror Space Antenna Reflectors Made of Composite Materials

Mirror space antenna reflectors should have low linear density and high dimensional stability. The information on the methods of designing reflectors made of composite materials is inconsistent. The need to design reflectors more advanced than the existing ones, prompts the development of original approaches to solving the problem. A method of designing mirror space antenna reflectors based on finite element simulation of the temperature and stress-strain state variants of composite structures for the given conditions of space flight is proposed. The feasibility of reducing the linear density and increasing the dimensional stability of mirror space antenna reflectors as compared to the existing designs is shown.
