Abstract
Space structures encounter various special environments in space. One of these environments is severe thermal condition. Difference of temperature of space structures during day-time and night-time is about 200 kelvin. These severe thermal conditions cause thermal deformation of the structures. In fact, we observed the signal level of radio wave from the LDR (Large Deployable Reflector) of the ETS-VIII (Engineering Test Satellite -VIII) changing during the Earth eclipse. This phenomenon may be caused by thermal deformation of the LDR. This thermal deformation is a key issue to maintain the accuracy of communication beams reflected by the space antenna. Analysis of thermal deformation of the LDR is carried out, and a new suppression scheme for thermal deformation is proposed in this paper.
