The combination of a solar array and a communication antenna can reduce the entire mass, physical size, and cost in space applications. Currently, related studies mainly focus on the combination of the two structures on the one flat plate structure (FPS). Compared with the FPS, a paraboloid structure has a lower surface density and higher conversion efficiency. Therefore, a novel space large deployable paraboloid structure with power and communication integration (SSPCI) is proposed and designed in detail, for spacecraft on a sun synchronous earth orbit; it consists of a cable mesh membrane reflector (CMMR), an energy conversion device (ECD), and a three-extensible-rod (TER) pointing mechanism. To achieve the goal of integrating power and communication, the TER pointing mechanism drives the CMMR/ECD to track the sun in the sunshine region or to turn to face the ground station/other target in the Earth’s shadow region. Then, through simulation analyses of the deploying process, static force at a limit orientation, and sun tracking process of the SSPCI, it is proved that the SSPCI is feasible and has satisfactory performance. Finally, deploying experiments of the folded hoop of the CMMR and sun tracking experiments of the TER pointing mechanism on the ground were carried out successfully, which proves that the folded hoop can be deployed successfully with fairly high deploying dependability, and the TER pointing mechanism is feasible for the SSPCI from the mechanism principle and the control mode in space applications indirectly. Moreover, the tracking accuracy of the TER pointing mechanism is estimated to be within ±0.4° although the machining precision of its components is not high.

具有电源和通信集成的新型空间大型可展开抛物面结构

太阳能电池阵列和通信天线的组合可以减少空间应用中的整体质量，物理尺寸和成本。当前，相关研究主要集中在一种平板结构（FPS）上两种结构的组合上。与FPS相比，抛物面结构具有较低的表面密度和较高的转换效率。因此，针对太阳同步地球轨道上的航天器，提出并详细设计了一种新型的具有电源和通信集成的空间大型可展开抛物面结构（SSPCI）。它由一个电缆网状膜反射器（CMMR），一个能量转换装置（ECD）和一个三伸杆（TER）指向机构组成。为了实现整合电力和通讯的目标，TER指向机制驱动CMMR / ECD跟踪阳光区域的太阳，或转身面对地球阴影区域的地面站/其他目标。然后，通过对SSPCI的展开过程，极限方向的静力和太阳跟踪过程的仿真分析，证明了SSPCI是可行的并且具有令人满意的性能。最后，成功进行了CMMR折叠式铁环的展开实验和TER指向机构在地面上的太阳跟踪实验，证明了折叠式铁环可以成功地部署，并且具有较高的展开可靠性，而TER指向机制是从空间原理上的机理原理和控制方式来看，SSPCI的可行性是间接的。此外，
