摘要

作为接替国际空间站(ISS)的新空间站，正在考虑建立月球轨道载人基地“门户”，并研究通过“门户”进行载人月球表面探测。要实现载人月面探测，需要克服月夜恶劣条件的新技术。作为这些技术之一，提出了将无线电力传输(WPT)应用于探测器等航天器。WPT系统有助于提高隔热性能，是减轻航天器电池重量的理想选择。此外，为了抑制涡流的产生，还开发了磁性传输多层绝缘(MT-MLI)。在MT-MLI的WPT实验中，线圈之间的功率传输效率达到90%以上。此外，热真空试验表明，WPT和MT-MLI的组合减少了热泄漏。

Proposal and Evaluation of High-Heat Insulation System for Spacecraft by Using WPT

As a new space station succeeding the International Space Station (ISS), a lunar orbit manned base, called “Gateway,” is considered and manned lunar surface exploration via the Gateway is also studied. To realize manned lunar surface exploration, new technologies are required to overcome the severe condition of the lunar night. As one of these technologies, applying wireless power transfer (WPT) to a spacecraft, such as a rover, is proposed. The WPT system contributes to the improvement of heat insulation performance and is ideal for reducing the weight of the battery of the spacecraft. In addition, magnetic transmissive multi-layer insulation (MT-MLI) is developed to suppress the generation of eddy currents. In WPT experiments with MT-MLI, the power transmission efficiency between coils is 90 % or more. Furthermore, thermal vacuum tests demonstrate that the combination of WPT and MT-MLI reduces thermal leakage.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
