项目摘要
Advanced utilization of solar energy will be an important technology for future space development. A solar concentrating system coupled with optical fibers was designed for high temperature material processing in space. Cassegrainian optics were used for the first-stage solar concentrator in order to fit the rim angle with the maximum angle for optical fibers used in this experiment. The strongly diverged solar rays at the exit of the optical fiber bundle are reconcentrated by Compound Parabolic Concentrators (CPCs). Using the system we can obtain the spatially fixed and stable high temperature point because of the flexibility of the optical fiber bundle. Its concentration ratio was measured for evaluate the optical performance of the CPC. It was revealed that the experimental value was nearly equal to the theoretical one. For simulating the space experiment on lunar surface, the temperature distributions in lunar regolith was analyzed by the finite element method coupled with raytracing method. It is shown that the CPC is useful to obtaining the high temperature for material processing on lunar surface.
太阳能的先进利用将是未来空间发展的一项重要技术。设计了一种用于空间高温材料加工的光纤耦合太阳能聚光系统。第一级太阳能聚光器采用卡塞格伦光学器件,以使边缘角与本实验中使用的光纤的最大角度相拟合。在光纤束出口处强烈发散的太阳光线被复合抛物面聚光器(CPC)重新聚集。利用光纤束的柔性,可以获得空间固定的稳定高温点。通过测量其浓度比来评价CPC的光学性能。结果表明,实验值与理论值基本一致。为模拟月球表面空间试验,采用有限元法结合射线追踪法对月壤温度场进行了数值模拟。结果表明,CPC可用于获得月球表面材料加工的高温。
