Abstract

The effects caused by the exposure to LEO environment on the primary structure of a solar array are here presented and discussed in detail. The synergistic damaging components featuring LEO environment are high vacuum, thermal cycling, neutral gas, ultraviolet (UV) radiation and cold plasma: the combined effects due to these environmental elements are simulated by means of experimental "on ground" tests performed by means of the Space Environment Simulator (SAS) together with numerical tools provided by the Space Environment Information System (SPENVIS) developed by the European Space Agency, ESA. A "safe life" design for a solar array primary structure is developed, taking into consideration the combined damaging action of the LEO environment components and thus coupling results from both numerical and experimental simulation within the framework of a standard finite element method (FEM) based design. The expected durability of the solar array primary structure, made of laminated sandwich composite, is evaluated assuming that the loads exerted on the structure itself are essentially dependent on he thermo-elastic behaviour: the optical degradation of surface materials and the stiffness and strength degradation of structural elements are taken into account to assess the global structural durability of the solar array under operative conditions in LEO environment.
