- Summary, etc.
- <p>In recent years, growing demand of observation from orbit require the development of satellites with high resolution observational instruments. To realize high resolution observation, optical structure with light weight and low thermal expansion is important, which is needed for big mirror reflector with limited payload, and thermal stability of the instruments. In this work, we developed the designing and forming method for cylindrical advanced grid structure composed of Carbon Fiber Reinforced Plastics (CFRP) applying as the optical structure; it has light weight and low thermal expansion. In this paper, to reveal the thermal deformation behavior of the advanced grid structure, we analyzed some grid structure models of Finite Element Method (FEM), and showed that axial expansion of the advanced grid structure bear a linear relationship with ``structure ratio,'' which is the ratio of rib width to grid interval. In addition, we made a trial model of the advanced grid structure and measured axial expansion. As a result of measuring, axial expansion of the trial model was lower than 0.1μ ε/K, and we showed that the advanced grid structure can be applied as the optical structure with low thermal expansion. </p>
