The potential for placing large, ultralightweight precision reflectors in space is currently being investigated through use of membrane structures. Their capacity for reducing launch mass and stowed volume is being exploited. However, on-orbit performance will require an understanding of the effects of thermal loads on reflector surface Precision. Thermal load effects cut both ways, and selective heating of the reflector may someday be used to Effect desirable changes in the surface profile. Both theoretical and experimental analyses are provided of an Inflated membrane reflector with a thermal load acting on its surface.
