Ceramic/glass ceramic type mirror fixing device for satellite observation type spacecraft, has locking part compressing terminal part according to direction parallel to intermediary part, and fixation unit fixing locking part on structure

摘要

The device has a locking part (33) compressing a terminal part of a glass excrescence (11) according to direction parallel to an intermediary part of the excrescence. A fixation unit fixes the part (33) on an embarked structure. The unit (33) is made of invar type thermal dilatation material with low coefficient and has openings with a locking screw (77) to block the part (33) against the excrescence. Skids assure contact between the terminal and locking parts and are made of aluminum type high thermal dilatation coefficient material. Surfaces of the skids have a layer of gold type material.
