ABSTRACT:
A resiliently compliant, variable stiffness wire mesh structure, primarily for space applications, characterized by its lightweight construction, its compact stowage and deployment capability, and its ability to maintain its nominal shape under widely varying thermal conditions. The structure has a frame supporting a wire mesh including spring-like longitudinally compliant wires which are terminally secured to the frame to constitute primary structural elements of the mesh and are prestressed in a manner such that the compliant spring wires in different sections of the mesh have differing spring rates or stiffness. This non-uniform stiffness of the mesh is designed to maintain the mesh taut under widely varying thermal conditions and thereby avoid the formation of slack in the mesh wires which would allow out-of-plane displacement of the mesh. The described mesh structure is a wire mesh antenna reflector for space applications.
