ABSTRACT:
A wire mesh structure, primarily for space applications, characterized by its lightweight, its compact stowage and deployment capability, and its ability to maintain its shape under widely varying thermal conditions. The structure has a frame supporting a wire mesh including wires which are terminally secured to the frame and constitute the primary structural elements of the mesh. These structural wires are preformed to a spring-like configuration which renders the wires resiliently compliant with a low spring rate in the endwise direction and are stretched to produce a predetermined tension preload in the wires when the mesh is installed on the supporting frame. This preload retains the mesh in a taut condition under widely varying thermal conditions and thereby prevents the formation of slack in the mesh which would allow out-of-plane displacement of the mesh. The invention also encompasses a method of fabricating the mesh and the mesh structure and is described in relation to a wire mesh parabolic dish antenna.
