Abstract
In this work the shape characteristics of a parabolic structure that consists of an initially flat circular membrane subject to solar radiation pressure in the space environment are examined. This problem arises in the analysis of space systems such as solar power collectors and solar sails. This paper presents parametric studies aimed at determining the power concentration capacity of a non-ideally reflecting flat circular membrane as a function of its radius size and thickness. The shape of the deformed membrane is close to parabolic. Both numerical simulations and analytical study show that the thin membrane subject solely to solar radiation pressure can concentrate the sunlight power several hundred times.
