摘要： A collapsible conductive material includes a generally mesh-configured, collapsible surface, that defines the intended reflective geometry of an antenna, and a distribution of tensionable cords and ties, which attach the reflective mesh to an inflatable support structure. The antenna is fully deployed once the inflatable support structure is inflated to at least a minimum pressure necessary to place the attachment tie/cord arrangement in a tension that causes the reflective surface to acquire a prescribed (e.g., parabolic) geometry. Preferably, the inflation pressure is above the minimum value, so as to allow for pressure variations (drops) within the support structure.

摘要： A splined radial panel solar collector structure approximates compound curvature surfaces by a three-dimensional arrangement of compactly stowable flat reflective panel segments mounted on a collapsible, space-deployable support structure of linear components. The support framework is formed of an umbrella-like framework of radially-extending ribs, struts and cords which deploy away from a central hub to form a system of radial trusses. A semirigid reflective surface structure is divided into sections of radial panels which are supported and shaped by an arrangement of radially tensioned flexible tape members aligned with the ribs. Connecting ties between the tapes and the ribs cause the tapes to assume a catenary curve. The ribs and flexible tape members are bridged circumferentially by sets of cords and ties to which the panels are joined. These cord and tie pairs place the panels in bending to effect a "splined" approximation of a parabola in the radial direction. The panels are arranged in a side-by-side relationship so as to be foldable in the circumferential direction during stowage. The panels are also discontinuous in the radial direction along lines connecting adjacent rib hinges in order to allow the reflective surface to be folded at the hinge points during stowage. As a result, each gore is effectively subdivided into a number of radial sections determined by the number of hinges along each rib and associated tape member. Openings are provided between the ends and sides of the panel strips so as to permit relative movement during folding and deployment, and to allow the panels to expand and contract with temperature change.
摘要翻译：花键径向板太阳能收集器结构通过安装在可收缩的，可部署空间的线性部件支撑结构上的紧凑可收缩的平面反射板段的三维布置来近似复合曲率表面。支撑框架由径向延伸的肋，支柱和绳索的伞形框架形成，其从中心毂部分远离以形成径向桁架系统。半刚性反射表面结构被分成径向面板的部分，其通过与肋对准的径向张紧的柔性带构件的布置来支撑和成形。带子和肋骨之间的连接件使带子呈现一个悬链线。肋和柔性带构件通过一组电线和连接件周向桥接，面板连接到该电线和连接件上。这些绳索和连接对将面板弯曲以在径向上实现抛物线的“花键”近似。这些面板以并排的关系布置，以便在装载期间可沿圆周方向折叠。面板也沿着连接相邻的肋铰链的线沿径向不连续，以便在收起时允许反射表面在铰链点处折叠。结果，每个孔被有效地细分成由沿着每个肋和相关联的带构件的铰链的数量确定的多个径向部分。在板条的端部和侧面之间设置有开口，以便在折叠和展开期间允许相对移动，并且允许面板随温度变化而膨胀和收缩。

摘要： A space deployable antenna reflector surface is formed as a continuous laminate that is shaped to conform with a prescribed energy-focusing surface geometry. The laminate is formed of very thin layers of flexible material, such as very thin sheets of graphite epoxy, containing collapsible radial and perimeter stiffening regions or stiffeners. Due to its thinness, the reflector laminate is collapsible into a folded shape, that facilitates stowage in a restricted volume, such as aboard the space shuttle. The stiffening elements of the laminate antenna structure of the invention facilitate deploying and maintaining the reflector in its intended geometric shape, and collapsing the reflector laminate into a compact serpentine stowed configuration.
摘要翻译：可空间展开的天线反射器表面被形成为连续层压体，其被成形为符合规定的能量聚焦表面几何形状。层压板由非常薄的柔性材料层形成，例如非常薄的石墨环氧树脂片，其包含可折叠的径向和周边加强区域或加强件。由于其薄度，反射器层压板可折叠成折叠形状，其有助于存放在有限体积内，例如在航天飞机上。本发明的层压天线结构的加强元件有助于将反射器展开并保持其预期的几何形状，并将反射器层压板塌缩成紧凑的蛇形收起构型。
