“四极型”防辐射航天器构架设想

采用"四极型"布置的主动静电场防辐射方法,减少使用厚重的防辐射材料,减轻发射质量。主舱体和金属防护球的外壳结构采用柔性材料,其支撑架能够通过机械结构灵活收缩膨胀。采用卷式薄膜太阳翼,展开前卷装在用于支撑金属防护球的外部支撑杆内壁中。设计结果表明,此航天器构架能够自由伸缩和膨胀,可提高空间利用率,从而满足一次发射的需求,并可长期使用,具有较好的经济效益。

Quadrupole Electrostatic Radiation Shielding for Spacecraft

The quadrupole active electrostatic shielding is adopted to reduce the launch mass. Flexible materials are used in the shell of both main cabin and metal protective balls to save launch space and satisfy the requirement of one-time launch. The supporting skeleton of flexible materials can retract and expand freely. Moreover, the rolling thin film solar arrays are used and before expanding they can be rolled in the external hollow rods which support the metal protective balls. It is shown that the spacecraft architecture can expand flexibly to improve space utilization, and it could satisfy the requirements of one-time launch and reusable to achieve great economic benefits.
