SCMeRe-Shape Control of Membrane Reflectors
Large space telescopes are constrained by system mass and available space in stowed configuration.With the use of Gossamer structures,made of membranes or thin shells of reflecting materials,ultra large,light-weight telescopes can be envisioned.This project addresses some of the scientific and technological challenges to make large space reflectors possible.To achieve this,the consortium consists of four groups with complementary expertises,respectively in active control of piezoelectric structures(Active Structures Laboratory-Université Libre de Bruxelles),deployable space structures and membrane wrinkling(Deployable Structures Laboratory –University of Cambridge),optics and reflector metrology(Centre Spatial de Liège)and numerical methods for highly nonlinear structures(Research Institute of Civil Engineering and Mechanics,University of Nantes).Research activities have initiated with a review of earth-borne adaptive optics and followed the setting of an experimental adaptive optics bench and the development of a simulator of an adaptive optics system.
