高エネルギー物質研究会では,アンモニウムジニトラミド(ADN)を基剤とした高エネルギーイオン液体(ADN系EILs)を推進剤とした衛星用化学推進系の研究開発を進めている.ADN系EILsは固体エネルギー物質の混合のみで調製可能であり,低蒸気圧,高エネルギー密度という特性から,高性能かつ安全な推進剤となることが期待される.数年以内の軌道上実証を目指し,合成から運用までの一貫した研究開発を進めている.本年度は,小型連続反応器を用いたADNの合成,これまでに見出された手法に基づくEILs組成のデザイン,レーザーおよび電解を用いたEILsの新規点火方式の実現可能性評価,EILsの安全利用に向けた化学安定性と材料適合性試験を進め,実用化に向けた技術の高度化がなされた.今後はスラスタの試作および推進性能の実証を行い,化学推進系としての成立性を明らかにする., We have been conducting research and development on chemical propellants using high-energy ionic liquids based on ammonium dinitramide (ADN-based EILs) for micro chemical propulsion system. ADN-based EILs can be prepared only by mixing solid energetic materials, and are expected to be high-performance and safe propellants due to their characteristics of low vapor pressure and high energy density. To realize the on-orbit demonstration of propulsion systems using EILs within several years, we are advancing researches of component technologies, consistent research from synthesis to operation. This year, we have made advances in these technologies; synthesis of ADN using a flow reactor, the design of EILs, the feasibility evaluation of a new ignition method of EILs using laser and electrolysis, and the chemical stability test for safe use of EILs. In the future, we will make a prototype of the thruster and demonstrate the propulsion performance to clarify its feasibility as a chemical propulsion system., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA2130019001, レポート番号: JAXA-RR-21-002
