ABSTRACT:
A mechanism for isostatic fitting of a fragile element, such as a mirror, to a support, generally carried on board a spacecraft, is provided. The mechanism includes three identical connecting devices circumferentially distributed around the optical axis of the mirror. Each device has a flexible blade or plate, whose longitudinal axis is preferably oriented in a direction tangential to a circle centered on the optical axis. The cross-section of the flexible blade decreases progressively from a first end fixed to the support to a second end fixed to the mirror, through a deformable member. The deformable member is adapted to flex in order to permit a relative rotation about a radially oriented axis. The fixtures to the support and the mirror are provided by rods operating only in tension and compression.
