Abstract: Printed textiles and related manufacturing methods are provided. Textile materials can include laced mesh fabrics made of rigid components. The laced mesh structures are designed for space applications, including but not limited to adaptive and foldable reflectors, capturing systems, debris and micrometeorite shielding, shading systems, sample capturing, and various other applications. The laced mesh structures are used in the generation of tailored, unique radio-frequency antennas and receivers that allow for active tuning/receiving capabilities. The tailored structure can also include multi-material systems mixing dielectric and conductive layers for enhanced, tunable transmission. Laced mesh structures can also be used for enhanced thermal control of components, with the ability to tailor thermal conductivity and emissivity, to create thermal engineered components via the generation of localized or global thermal response (e.g. zone thermal control).

Abstract: A ballast member may be disposed within a vessel to reduce an active volume of the vessel through which the working fluid can circulate. For instance, a solar power system may include a solar receiver through which a working fluid can be circulated and at least one solar collector that is operative to direct solar energy toward the solar receiver to heat the working fluid. A tank is fluidly connected with the solar receivers such that the working fluid can be circulated through the tank. The tank includes an internal chamber and at least one ballast member within the internal chamber that reduces the active volume of the internal chamber.
