Résumé :

This paper discusses a new concept of the active spherical shell reflector made of polymer materials, which exhibits excellent areal density and stowability and paves the way to future lightweight large-aperture space telescopes for potential observation of various wavelengths. The shape control of a small-scale technology demonstrator is performed, and the design criteria of patterned electrodes is proposed. The stress-stiffening effect on the piezoelectric strain actuation is investigated and the influence of manufacturing errors on the structural dynamics is also considered to give a preliminary study on evaluating the morphing capability under complex environment in space.
