Chofu Aerospace Center, Japan Aerospace Exploration Agency (JAXA)(CAC)), Chofu, Tokyo, Japanデブリ増加の問題を解決する有効な手段として、混雑する地球周囲低軌道からの既存デブリの除去が挙げられる. 低コストでのデブリ除去を実現するため、JAXAでは高効率推進系である導電性テザー(EDT)によるデオービット技術の研究開発を進めている. 将来のデブリ除去システム実証では、実際にデブリに接近し推進系を取り付けて軌道降下させるが、EDT要素技術実証フェーズに比べてEDTの大型化・大電流化が必要となる. 本稿ではデブリ除去に用いるEDTの原理および特徴を紹介し、また将来のデブリ除去システム実証に備えて、EDTシステムのキーとなる要素の特性およびデブリ除去システム実証におけるテザー伸展やEDT推進によるデオービットについての数値解析結果について論じる.The increase in the amount of orbital debris has been becoming a serious problem for human space activities. One effective strategy to suppress space debris growth is an active removal of already existing large debris in the crowded low earth orbits. Toward the realization of cost-effective active debris removal (ADR) in the lower earth orbits, the Japan Aerospace Exploration Agency (JAXA) has been conducting research and development of an electrodynamic tether (EDT) as a very promising candidate of propulsion for deorbiting in ADR. EDT can generate sufficient thrust for orbital transfers without the need for propellant by utilizing interactions between the Earth's magnetic field and currents through the tether. In order to remove large debris objects with the mass of about 1-3 tons in the crowded regions (altitude of 800-1000 km), EDT requires a tether length of 5-10 km and several ampere of current. This paper describes the fundamentals of the electrodynamic tether including its advantages and disadvantages for ADR. In addition, for the preparation of the ADR system demonstration, we will introduce the characteristics of the key EDT system components, and the results of the numerical simulations of tether deployment and deorbit by EDT thrust using our system.形態: カラー図版ありPhysical characteristics: Original contains color illustrations資料番号: AA1630052052レポート番号: JAXA-SP-16-011
